Measure flow from outside a pipe. Designed for "difficult liquids" that would damage regular flow meters - wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. There is no obstruction to flow and no pressure drop. The non-intrusive, clamp-on ultrasonic sensor fits any pipe 1/2" (12.5 mm) Inside Diameter or larger.
Designed for pump stations, wet wells and tank level control, the Greyline PSL5.0 includes 6 control relays for pump control, alternation, level alarms, dialers or fault alarms. It features a non-contacting ultrasonic level sensor plus redundant sensing with connection of any 4-20mA level sensor. The PSL5.0 automatically stores relay run time reports for pump performance.
The SLT5.0 continuously measures, displays, and transmits level in tanks and pumping stations, or monitors and totalizes Open Channel flow through any flume or weir. Includes a non-contacting ultrasonic sensor which is rated Intrinsically safe, 4-20mA output, backlit LCD display, control relays and many optional components like 2-million point datalogger.
