Ideal for sewage pump stations, lift stations, wet wells and tank level control with a non-contacting ultrasonic sensor mounted above the liquid. The new Greyline PSL Level Controller has 6 independently programmable control relays for pump or valve control, level alarms, dialers, temperature alarm and echo-loss alarm.

Mount the sensor in the tank or wet well and install the watertight electronics in the control room or any location within 500 ft / 150 m. Use the simple, built-in calibrator to set up measurement range and relay set points. Or use the free "PSL Remote" Windows software to calibrate from your PC by RS232 connection, or through modems over a regular phone line.

PSL Relay/Pump run time data is stored automatically by the instrument. Retrieve reports directly through the PSL display, or through its RS232 output. The PSL Remote Windows software program displays a pump run time graph and will output data to a spreadsheet file or directly to a Microsoft Excel spreadsheet with DDE.

For hazardous locations, the ultrasonic sensor is rated Intrinsically Safe with an optional safety barrier. The standard PVC Sensor (optional Teflon) is rated for measurement ranges up to 32 ft / 10 m, or use the optional PVC Sensor rated for 50 ft / 15.6 m measurement range.
