The PSL 5.0 Pump Station Level Controller from Greyline Instruments is designed for sewage lift stations, wet wells and storage tanks. It includes a noncontacting ultrasonic sensor. A loop-powered pressure sensor can also be connected for redundant sensing in applications with foam or grease. It will continuously recalibrate the pressure sensor and automatically switch back and forth from ultrasonic to the pressure sensor as required. An automatic pump runtime logging and reporting system helps operators to plan pump maintenance and identify lazy pumps before they fail. 888/473-9546; www.greyline.com.
