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.

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.

1.6.1 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.

730 Bubbler Module
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.

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.

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
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).
3-1
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
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.
Bubble Line Carrier
3-2
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
3-3
730 Bubbler Module
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

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
studs. In an earthen channel, the plate can be held in place by
driving in stakes.
Sensor Mounting Plate
3.2.2 U-Channels
It is possible to mount the bubble line retainer in a U-channel
with a scissors ring base section. Attach the base section to the
channel wall with studs fired from a power-activated stud gun.
Consult the factory for more information, if you must mount the
bubble line in a U-channel.

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.
4-1
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.
