SINGLE INTELLIGENT PUMP CONTROL PANEL FOR SEWAGE LIFTING PUMP, WITH THREE PHASE, AC380V/50HZ
Model L931-S
Model L931-S is specially designed for sewage pumping system, by adopting level transmitter with 0.5-4.5V analog signal, pump user can easily set the different liquid depth for sewage pump operation and observe the dynamic liquid depth in the sump or sewage tank.
Typical usage scenarios include:
-Chemical, petroleum, pharmaceutical, mining, paper making industry
-Cement plant, steel plant, power plant, coal processing industry
-Municipal waste water treatment plants
-Drainage system
-Municipal engineering
-Construction site
Application & Control characteristic:
Connecting 0.5-4.5V level transmitter to replace liquid probe, float switch
Pump start and stop according to different depth value setting
