730 Bubbler Module  
Section 1 Introduction  
1.1 Introduction  
The 730 Bubbler Module is one of Teledyne Isco’s inter-  
changeable modules for the Avalanche and 6700 Series Sam-  
plers. The module uses a differential pressure transducer and a  
flow of bubbles to measure liquid levels up to ten feet. The  
bubbler is unaffected by wind, fluctuations in air or liquid tem-  
peratures, turbulence, steam, foam on the surface, corrosive  
chemicals, debris, oil, floating grease, or lightning.  
You can install the module only on a 6712 or 6700 controller. The  
bubble line can be used in nearly any location with a known  
level-to-flow relationship.

WARNING  
The module has not been approved for use in hazardous  
locations as defined by the National Electrical Code.  
Installation of this module in a hazardous location may  
cause fire or explosion resulting in death, personal injury,  
or property damage. Before installing any device in a  
dangerous location, review safety precautions in your  
sampler manual. Check applicable guidelines, codes and  
regulations of federal, state, city, and county agencies.

Section 1 Introduction  
1.2 Connecting to the  
Sampler  
To install the module:  
1. Turn the sampler off.  
2. Remove the connector cap in the module bay and move it  
aside.  
3. Slide the module into the bay.  
4. Push against the module to be sure the connector is fully  
seated.  
To remove the module:  
1. Turn the sampler off.  
2. Press the silver button on top of the module and pull the  
module from the bay.  
3. Replace the connector cap in the module bay.  
1.3 Installation Checklist  
1. Check the desiccant cartridge. Make sure the desiccant is  
active (blue in color) and remove the red cap.  
2. Install the module and turn the sampler on.  
3. Install the bubble line in the flow stream.  
4. Connect the bubbler line to the module.  
5. Program the sampler and calibrate the module’s level read-  
ing.  
6. Run the program.  
Note  
You should install the module before turning the controller on.  
When the controller is turned on, it looks for a module. The  
controller will not recognize a newly installed module if it is not  
seen during this power-up routine. If you install a module while  
the controller is already on, turn the controller off and then on  
again to reconfigure the controller to use with the module.  
1.4 Calibrating the  
Bubbler Module  
After the sampler, module, and bubble line have been installed at  
the site, calibrate the module by measuring the depth of the  
water and adjust the reading to match.  
It is possible to calibrate the module in a container of water. Use  
a bubble line of the same length as the one at the installation site  
to get an accurate and reliable calibration.  
1.5 Power Consumption  
The 730 Module consumes a considerable amount of power. A  
nickel–cadmium battery may not be sufficient to finish a sample  
routine. For example, the battery should be expected to complete  
three sampling routines of 24 samples, each sample 200 ml, at  
one sample per hour with a 10 foot suction line and a 5 foot head.  
But if the routine is changed to 24 samples, 4 samples per bottle,  
each sample 250 ml, at 15 minute intervals, with the same  
suction line and head height, the battery does not have the  
capacity to complete one routine. Teledyne Isco recommends  
using a lead–acid battery or a 913 or 923 power pack when using  
the 730 Bubbler Module.

Section 1 Introduction  
1.6 General Mounting  
Considerations for the  
Bubbler  
This section contains some general information regarding the  
installation of the 730 module. More detailed installation infor-  
mation can be found in Section 3 Installation Methods.  
1
1.6.1 Line Length  
A standard 25 foot (7.6 m) length of /8" (0.32 cm) ID vinyl line is  
shipped with the module. We recommend that you do not use  
lengths longer than 25 feet. Please consult with the factory if  
your installation requires a nonstandard setup.  
Cut the bubble line to the shortest usable length. This will min-  
imize friction head effects in the line and also will reduce the  
amount of line exposed to cuts, kinks, etc. This will also improve  
the response time to changing levels and make the purge more  
effective.  
The bubble line should be routed and secured so that it does not  
disturb the flow. Do not kink the tubing or restrict the airflow by  
over-tightening the mounting hardware.  
1.6.2 Attach the Bubble Line The vinyl bubble line attaches directly to the barbed fitting.  
to the Module  
Simply push the tubing over the fitting.  
Barbed Fitting  
Vinyl Bubble Line  
1.6.3 Bubble Line Position in The bubble line outlet does not need to be at the bottom of the  
the Stream  
stream. In fact, positioning the bubble line outlet above the  
bottom can be beneficial if the stream carries large amounts of  
solids or is subject to silting.  
The simplest installation method attaches the bubble line to the  
side of the flow stream with the bubble line outlet positioned  
below the lowest expected level.  
Recommended  
Bubble Outlet Depth  
B
To measure the liquid level down to the actual “zero” level of the  
primary device, Teledyne Isco recommends placing the bubble  
line outlet at least 1 to 2 inches (2.5 to 5.1 cm) below the  
primary device “zero” level to avoid measurement failures when  
the liquid level is even with the outlet. The module cannot accu-  
rately measure levels that are even with or below the bubble line  
outlet.  
Zero  
A
A. The recommended depth ranges from  
the bottom to 1 inch below the zero level.  
B. This position would be unable to  
measure low levels through the primary  
device.

Section 1 Introduction  
1.6.4 Bubble Line  
Extensions  
For some applications, a stainless steel tube may be easier to  
install in the flow stream than the plastic bubble line because of  
its relative rigidity. The vinyl bubble line attaches by simply  
slipping the vinyl tube over the end of the extension. Contact  
your Teledyne Isco representative about purchasing a stainless  
steel bubble line extension.  
A copper extension to the bubble line is advantageous in applica-  
tions where algae tends to grow in the bubble line. The copper  
salts released by the tubing are algicides that tend to inhibit the  
growth of algae. However, the copper tubing may not be com-  
patible with the flow stream. Attach the copper bubble line  
extensions to the bubble line in the same way as the stainless  
steel extensions.  
1.6.5 Installing the Bubble  
Line in a Primary  
Device  
Primary devices such as weirs or flumes will usually specify a  
head (level) measurement point. It is important to place the  
bubble line outlet at this point to convert levels to flow rates cor-  
rectly. For more details about locating the head measurement  
point, refer to the Isco Open Channel Flow Measurement  
Handbook, or to information provided by the primary device  
manufacturer.  
Flume Bubble Line Fittings – Because of the variety of  
primary measuring devices and installations, no comprehensive  
bubble line installation instructions are practical. However, there  
are valid general observations on bubble line installation that  
can be made. You can have most flumes specified to include a  
bubbler fitting. In new construction, this is highly recommended.  
It may even be possible to modify an existing installation to  
include a permanent bubbler fitting.  
Stilling Wells – If the primary device includes a stilling well,  
you should install the bubble line in the stilling well. However,  
not all stilling wells are suitable for bubble line installation. If  
the well is subject to silting or buildup of foreign material, you  
should probably avoid it and mount the bubble line in the flow  
stream proper.  
Open Channel Installation – Attach the bubble line to the  
side of the flow channel or flume. Make the attachment so it  
causes a minimum amount of disturbance to the flow stream. If  
possible, cut a groove in the side of the channel, place the bubble  
line in the groove, and then grout over the groove.  
Alternately, you can attach the bubble line to the side of the  
channel, and then grout over the line to form smooth, sloped  
lead-in and lead-out surfaces. However, you may simply attach  
the bubble line to the side of the channel or the upstream side of  
a weir.  
Note  
When installing the bubble line in a high-velocity flow stream  
(exceeding 5 ft/sec or 1.5 m/sec), please consult with the Tele-  
dyne Isco Customer Service Department for recommenda-  
tions.

options are available. If programmed for LEVEL ONLY the  
option will be LEVEL. If programmed for FLOW METER the  
options will be LEVEL and FLOW. For more information about  
programmed enables, refer to the sampler manual.  
When the sampler is configured for use with the module, a  
memory partition is reserved. The module readings are stored in  
this sampler memory partition. For more information on data  
storage and partition management, see the sampler manual.  
2.3.1 Recovering Module  
Data  
The stored module data can be collected or viewed as “reports.”  
Three of the sampler reports contain module information, and  
are shown in Figure 2-1. Refer to the Sampler Instruction  
Manual for collecting and reading the reports.  
Note  
An * (asterisk) appears next to the reading if the module was  
unable to take a reading. If an asterisk appears, the reading  
displayed is the last available reading.

730 Bubbler Module  
Section 2 Programming the Module  
2.4 Operation of the  
Bubbler System  
When measuring flow rate, the module is used with a primary  
measuring device (typically a weir or a flume) or other open  
channel flow arrangement where a known relationship exists  
between level and flow rate (refer to Table 2-1 Flow Conversion  
Types). The level measuring device is a bubbler which measures  
the liquid level in the flow stream. The level reading is converted  
into a properly scaled flow rate value.  
The module contains microprocessor-controlled circuitry to cal-  
culate level from the signals produced by the pressure trans-  
ducer, and communicate with the 6712 controller.  
The module’s bubbler system works as follows: A small com-  
pressor pumps air into a reservoir. This air is slowly released by  
an orifice into a bubble line. The other end of this tube is sub-  
merged in the flow stream. Inside the module, the bubble line  
also connects to one side of a differential pressure transducer. As  
air is released slowly into the bubble line by the orifice, pressure  
builds inside the line to force the air out of the line into the flow  
stream. When there is enough pressure to counteract the hydro-  
static pressure of the flow stream, a bubble will be forced from  
the end of the line. The amount of pressure required to force the  
bubble from the end of the line is directly dependent on the  
hydrostatic pressure of the flow stream over the end of the  
bubble line.  
The pressure transducer inside the module senses this pressure  
and converts it into an electrical signal that the module converts  
into level. The 6712 controller then calculates flow rate and total  
flow from the level measurement and lookup tables for the  
primary device you are using.  
The module produces the pressurized air supply, regulates the  
rate of air to the bubbler tube, measures the pressure in the  
bubbler tube, purges the air line, compensates for drift, and other  
functions.  
2.4.1 Purges  
Periodically, the module releases a high pressure, unregulated  
burst of air directly into the bubble line. This is done to clear the  
line and prevent any buildup of debris at the bubble line outlet.  
2.4.2 Automatic Drift  
Compensation  
The module measures the output of the pressure transducer at  
zero pressure. When the module is first turned on, and every 15  
minutes after that, the processor actuates the automatic drift  
compensation valve, which connects the input port of the  
pressure transducer to the reference port. With the two ports  
connected, it then measures the output offset.  
The module stores this offset reading in memory and uses it in  
level calculations. The repetition of this process causes any  
pressure transducer or amplifier drift to cancel out, eliminating  
the most significant cause of drift, especially when operating at  
low water levels.

2.5 Alternative Flow  
Because of the characteristics of bubbler flow measurement,  
there may be some installations where the bubbler method is  
either unreliable or inaccurate. In these instances, it is worth-  
while to consider using an alternate method of flow mea-  
surement.  
Measurement Systems  
In addition to the 730 Module, Teledyne Isco offers three other  
types of plug-and-play flow modules in the 700 Series: the 720  
Submerged Probe Module, the 710 Ultrasonic Module, and the  
750 Area-Velocity Module.  
Information about these flow modules is available from the  
factory. Call for more information or visit our Web site at  
www.isco.com.

730 Bubbler Module  
Section 3 Installation Methods  
The bubble line may be installed in many different channel  
types, which are summarized here. For more detailed infor-  
mation about mounting options, consult your Isco Mounting  
Rings Installation and Operation Guide. See Figure 3-4 for  
examples of the mounting methods described in this section.  
3.1 Installation in Round  
Pipes  
Teledyne Isco offers four systems for installing bubble line in  
round pipes:  
• Flow Metering Inserts  
• Isco Spring Rings  
(for pipe diameters of 15 inches or less)  
• Scissors Rings  
(for pipe diameters from 16 to 80 inches)  
• Street Level Installation System  
3.1.1 Flow Metering Inserts  
Flow metering inserts are available for use with the module that  
you can temporarily install inside round pipe sewers and flow  
streams to create a primary device inside the pipe. These inserts  
are available to fit 6", 8", 10", and 12" pipes and install from  
street level.  
The inserts create a restriction in the flow stream and may cause  
clogging. Where this could be a problem, we suggest using one of  
the other three installation systems instead.  
Because the flow metering inserts are installed from street level,  
it is not possible to measure the level. Instead, you must set the  
level to zero before installing the flow metering insert in the pipe.  
Set the level to zero using the following instructions:  
1. Install the module in the Sampler and remove the red  
cap from the desiccant cartridge.  
2. Assemble the flow metering insert to the length that will  
be installed.  
3. Attach the bubble line to the module. The inside of the  
bubble line must be dry and unobstructed.  
4. Turn on the sampler and wait 2 to 3 minutes to allow the  
bubbler’s air system to stabilize.  
5. Select Program from the sampler’s main menu and step  
through the screens until the “Current Level” screen  
appears. (Detailed programming instructions appear in the  
sampler manual.)  
6. Adjust the level to read zero (0.00 feet or meters).

730 Bubbler Module  
Section 3 Installation Methods  
You may exit the programming after setting the current  
level to zero. When you install the flow metering insert, the  
bubbler module will then provide liquid level readings  
based on this zero level.  
7. Proceed with installing the insert into the pipe.  
3.1.2 Spring Rings  
Consult your Isco Mounting Rings instruction manual for  
detailed hardware information.  
Stainless steel spring rings simplify probe installation in 6 to 15  
inch round pipes. Teledyne Isco offers five diameter sizes: 6, 8,  
10, 12, and 15 inches (15.2, 20.3, 25.4, 30.5, and 38 cm). A typical  
spring ring is shown in Figure 3-1.  
This self-expanding device compresses to slide into a pipe. When  
released, the ring secures itself against the wall with an inherent  
outward force.  
Figure 3-1 Spring Ring (6 to 15 inches)  
Preparing the Spring Ring:  
First attach the bubble line to the bubbler carrier assembly  
(contact your Teledyne Isco representative to purchase the  
bubbler carrier). Then fit the carrier onto the mounting tabs of  
the ring, making sure the tabs completely engage the slots in the  
carrier. This method of attaching the bubble line to the ring  
allows for easy removal in case service is needed later.

730 Bubbler Module  
Section 3 Installation Methods  
Route the vinyl bubble line away from the carrier and along the  
spring ring’s edge with holes. Secure the line in position by  
placing plastic ties through the holes and then locking them  
around the line. To prevent debris from collecting, attach the line  
so that it offers as little resistance to the flow as possible. Avoid  
loops or slack sections. Attach it neatly and closely to the spring  
ring.  
Installing the Spring Ring:  
Plastic  
Ties  
After the bubble line and carrier have been attached to the  
spring ring, the actual installation procedure is fairly simple.  
First, lower the spring ring assembly into the area of the pipe.  
Next, grasp the spring ring and compress it into a tight circle.  
Then push the ring up into the pipe the desired distance.  
When you have the ring positioned, release the ring, allowing it  
to expand outward. It may be necessary to rotate the ring to  
position the bubble line outlet in the bottom center of the pipe.  
This completes the installation.  
Spring Ring Preparation  
Under conditions of high velocity (greater than five feet per  
second or 1.5 meters per second), the spring ring may not have  
sufficient outward force to keep it tight against the pipe. The flow  
could lift the ring off the bottom of the pipe, or even carry it  
downstream.  
This problem is more prevalent in the larger diameter pipes (10,  
12, and 15 inch) and in pipes with a smooth inner surface  
(plastic, for example). If any of these conditions are present, or if  
movement of the spring ring is detected or suspected, you must  
anchor the ring in place. You can do this by shooting studs  
through the ring into the pipe or by other appropriate means. In  
some cases, it may be sufficient to increase the outward force of  
the ring by bending it into a less rounded shape.  
3.1.3 Scissors Rings  
Consult your Isco Mounting Rings instruction manual for  
detailed hardware information.  
For pipes larger than 15" in diameter, Teledyne Isco offers the  
adjustable Scissors Ring (also known as the Universal Mounting  
Ring). This device consists of two or more metal strips that lock  
together with tabs to form a single assembly. There is a base  
section where the sensors are mounted, one or more extension  
sections (usually), and a scissors section at the top that expands  
the entire assembly and tightens it inside the pipe. The scissors  
mechanism includes a long screw that increases the width as it is  
tightened.  
The assembled rings fit pipe diameters from 16" to 80". Secure  
5
the unit in place by tightening the scissors mechanism with a /8"  
socket wrench or other suitable tool. Ring sections are .040" thick  
half-hard 301 stainless steel sheet. All other parts are also  
stainless steel, except for the plastic cable ties in the hardware  
kit.  
Each extension, 1, 2, 3, and 4, adds 9.0", 21.5", 31.5", or 41.5",  
respectively, to the circumference of the ring. Used alone, the  
base section fits pipe that is approximately 16" to 18" in

Section 3 Installation Methods  
diameter. The 9.0" (the smallest) extension exists so that in  
larger pipe sizes, where large variations in circumference can  
occur, you can use one or two of these extensions to take up or  
remove slack, to bring the scissors mechanism into a position  
where it can be effectively tightened.  
Mounting ring kits are available for different pipe sizes. A kit is  
also available for partial pipe applications (see your Isco  
Mounting Rings Installation and Operation Guide). For a listing  
of part numbers and ordering information, see Appendix A.  
To prevent debris from catching on the cable, it is important to  
attach the cable to the mounting ring so it offers as little resis-  
tance to the flow as possible. Attach the sensor cable to the down-  
stream edge of the ring, using the self-locking plastic ties  
supplied with the ring. Place the ties through the holes in the  
edge of the mounting ring and then lock them around the cable.

3.1.4 Street Level  
Installation System  
The Street Level Installation System provides a way to install  
the probe in a round pipe without entering a manhole. This  
system uses multi-section poles and expansion rings that fit 6, 8,  
10, 12, and 15 inch round pipes in manholes as deep as 15 feet.  
The system includes an instruction manual.  
3.2 Other Installation  
Methods  
Teledyne Isco’s mounting hardware can be installed or adapted  
for use in many channels. The paragraphs below list additional  
bubble line installation methods.  
3.2.1 Rectangular,  
Trapezoidal, and  
Earthen Channels  
Teledyne Isco offers the Sensor Mounting Plate for these  
channels. The stainless steel plate has tabs to mount up to three  
sensors. The bubble line carrier also attaches to the tabs (see  
figure in the left margin). It is secured in concrete channels by  
driving studs into the channel bottom and bolting the plate to the

730 Bubbler Module  
Section 4 Maintenance  
The 730 Bubbler Module has no user serviceable parts. It is com-  
pletely sealed to protect the internal components. If you think  
the module requires repair, contact Teledyne Isco’s Customer  
Service Department.  
4.1 Desiccant  
Reactivation  
A cartridge on the side of the module dries the air inside the  
module and probe reference line. It contains a silica gel desiccant  
with a color indicator that changes from blue to pink, or yellow to  
green, when saturated. Pink or green desiccant cannot remove  
moisture and must be replaced or reactivated.  
A saturated desiccator will let moisture into the bubbler system,  
which can cause several undesireable effects, including:  
·
The moisture may block internal tubing and cause  
reading errors.  
·
The air in many installations contains fumes that  
will form acids in the presence of moisture. These  
acids may corrode internal components.  
·
At temperatures near or below freezing, there could  
be permanent damage if ice forms inside the air  
pump.  
To reactivate the desiccant, pour the desiccant out of the car-  
tridge into a heat-resistant container. Never heat the plastic car-  
tridge; it will melt. Heat the silica gel in a vented convection oven  
at 212° to 350° F (100° to 175° C) for two to three hours, or until  
the blue or yellow color returns. Allow the desiccant to cool and  
then refill the cartridge.  
CAUTION  
Desiccant may produce irritating fumes when heated. Observe  
the following precautions:  
• Use a vented oven in a well-ventilated room.  
• Do not remain in the room while the regeneration is taking  
place.  
• Use the recommended temperature. Avoid heating the desic-  
cant at higher than recommended temperatures.  
The desiccant’s ability to remove moisture may lessen with each  
saturation/reactivation cycle, resulting in a need for more fre-  
quent service. After several cycles, the desiccant may no longer  
be effective as it saturates too quickly. At this point, replace the  
desiccant.

730 Bubbler Module  
Section 4 Maintenance  
The filters in the end caps keep small pieces of the desiccant  
material from falling out of the cartridge. When the filters  
become soiled, clean with dish soap and water, then allow to dry.  
4.2 Hydrophobic Filter  
The hydrophobic filter prevents  
water from entering the module.  
Any amount of water will plug  
the filter. If the filter becomes  
Fitting  
plugged replace it.  
To remove the filter, turn it coun-  
terclockwise while making sure  
the black fitting does not rotate.  
Hydrophobic Filter  
Replacement hydrophobic filters,  
Isco P/N 60-2005-003, are  
available from Teledyne Isco.  
4.3 Bubble Line  
Maintenance  
Periodically inspect the bubble line to make sure that it has not  
become kinked or damaged in any way. If you find damage to the  
bubble line, replace it. A leaking or obstructed line will cause  
inaccurate level readings and lower battery life. (The pump must  
run more frequently.) If you need to replace the bubble line,  
install a new line the same way you installed the original. Gen-  
erally, the new line should be the same length as the old.  
If you replace the bubble line or if you change the outlet either by  
cutting off the tip or by installing a bubble line extension, you  
must recalibrate the level.  
Inspect the outlet of the bubble line regularly for any signs of  
clogging. Sediment or debris from the flow stream and algae can  
all clog the line. If the line is blocked, you can either clean it out,  
or simply cut off the tip.  
If algae growth is a problem, consider using a copper bubble line  
extension. The copper salts formed on a copper line will prevent  
algae growth.  
4.4 Repairing The Module The module has no user-serviceable parts. Its case is completely  
sealed to protect the internal components. To repair the unit, the  
case must be broken open and replaced. If you think your module  
requires repair, contact Teledyne Isco’s Customer Service  
Department for information on returning it to the factory.  
4.5 Flash Memory and  
Software Upgrades  
The module has Flash memory to store its software. With Flash  
technology, you can upgrade your module’s software without  
sending it back to the factory or replacing a chip.  
To update the module software, install the module in a 6712  
sampler. Then connect the sampler power source and turn the  
sampler on. Connect the sampler to a computer and follow the  
instructions received with your Flash Update program.
