Pump Station Controller
The new hybrid PSL 5.0 Pump Station Level Controller from Greyline Instruments (Massena, NY) features redundant level sensing. It includes a non-contacting ultrasonic sensor and users can also connect a loop-powered pressure sensor for redundant sensing in applications with foam or grease. The PSL 5.0 will recalibrate the pressure sensor automatically and switch back and forth from ultrasonic level to the pressure sensor as required. An automatic pump run time logging and reporting system helps operators to plan pump maintenance and identify “lazy” pumps before they fail. It includes an isolated 4-20mA output and 6 programmable control relays for pump control, pump alternation, and level alarms. Intrinsically safe sensors and a built-in data logger are optional.
