Ideal for pump 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.
