Fueling Stations  
Standard Control Systems for  
CNG Fueling Stations  
Designed for the small fueling facility...monitoring  
and controlling electric motor driven compressor.  
LEVEL I  
LEVEL I is an entry level controller system  
designed for the small fueling facility requiring  
only basic start and stop of the compressor  
and monitoring basic shutdown functions. It  
monitors and controls the electric motor  
driven compressor and the system loading and  
unloading devices.  
The LEVEL I controller is an extremely  
powerful system, yet user friendly. Its design  
incorporates the high technology Murphy  
SELECTRONIC® Micro-Controller™ series.  
Features:  
Automatic start and stop control  
Operating parameters field adjustable  
without reprogramming  
Includes hourmeter  
Extremely user friendly  
Operates load/unload devices  
Compatible with stand alone  
priority/sequential controls (see below)  
NEMA 4, 7, and 9 enclosure  
Additional Controls  
Stand Alone Priority and  
Sequential Controller  
The Murphy SELECTRONIC®  
Priority/Sequential Controller  
will monitor the Cascade or  
other high pressure storage  
banks and control the electric  
sequencing valves. The Priority  
Valves will sequence at operator  
selectable levels to fill the  
storage on fast fill packages. It  
will also monitor the vehicle  
dispenser flow rate and  
pressure, and will control the  
Sequential Valves and Shut-off  
Valves to maximize filling the  
vehicle in the minimum amount  
of time.

Suitable for larger stations with  
simplex or duplex compressor(s).  
LEVEL II  
LEVEL II is a mid-range system  
designed for the larger stations  
with more shutdown inputs  
being monitored than the LEVEL I  
control system. The LEVEL II  
system performs all the functions  
of the LEVEL I, plus is available  
for both single or dual electric  
motor or engine drive  
applications. A SELECTRONIC®  
Micro-Controller™ monitors  
control functions and displays  
status and faults in a two line  
alphanumeric LCD display. By  
selecting the appropriate Murphy  
SELECTRONIC® Micro-Controller™  
for the specified hazardous area  
classification (Div. 1 or Div. 2),  
non-explosion-proof end devices  
can be used. The LEVEL II  
Features:

LEVEL II Div. 2 Control System  
Monitor and control the entire fueling system  
including the Priority/Sequential valve operations.  
Communications modem on-board.  
LEVEL III  
LEVEL III is a comprehensive system  
designed to monitor and control the  
entire fueling system. It is available  
for both simplex or duplex electric  
motor or engine driven systems.  
The Murphy SELECTRONIC® Micro-  
Controller™ sequentially controls the  
compressor operations. It also controls  
the priority valves to maintain  
adequate storage pressure and the  
sequential valves which ensure  
maximum fill in minimum time.  
A built-in temperature compensator  
assures optimum fills.  
Features:  
PLC capabilities:  
Monitor 20 analog inputs  
120 VAC control circuit for customer  
supplied motor contactor  
Reliable microprocessor based  
control circuitry  
Available for areas rated NEC Class  
I, Division 1 or Division 2, Group  
D, and non-hazardous locations

Custom Valve Panels  
Priority/Sequential Valve Panels  
Murphy offers Priority/Sequential  
Valve Panels complete with  
Murphy Pressure Transmitters for  
use with the LEVEL III control  
system or the Murphy Stand-  
Alone Priority/Sequential  
Controller. These panels were  
designed to fail close valves for  
optimum operation. These  
panels can be provided on a plate  
or in a free standing NEMA 3  
weatherproof enclosure.  
Valve Panel for 2 fast fill drops, 1 slow fill  
header, and 3 bank cascade storage.  
Valve Panel for 4 fast fill drops, 1 slow  
fill header, and 3 bank cascade storage.
