FW Murphy Control Systems for Alternative Fuel Fueling Stations CNG-92200H Revised 08-00 00-02-0149.
F WMurphy has been in the business of providing quality controls to the engine, pump, and compressor market since 1939. Most of the controls in use today were pioneered by Murphy to meet the needs expressed by OEM’s, packagers and users.
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.
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.
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.
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.
