Our PLCM open channel flow meter is an economical open channel flow meter， which measures level, flow rate and total volume of water flowing through weirs and flumes. The meter includes a non-contact ultrasonic level sensor to detect the water level and then calculates the flow rate and volume using the Manning equation and characteristics of the channel.
High detection accuracy, the flow meter measurement changes with 1mm, the accuracy of change in level is 1 mm;
Suitable for a variety of weirs and flumes, Parshall flumes (ISO), V-Notch weirs, Rectangular weirs(With or Without End Contractions) and custom Formula type weir;
Displays flow rate in L/S , M3/h or M3/min;
Excellent anti-interference capability;
Clear display with Graphical LCD(with backlight) ;
The cable length between probe and host up to 1000m;
The probe with leak-proof structure and IP68 protect grade;
Chemically resistant probe materials for maximum application flexibility;
Provided 4-20mA output and RS485 serial communication (MODBUS-RTU) output;
Provided programmable 6 relays at most for alarms;
Three button for programming or remote control for easy configuration and operation（opt.）;
It is well suited for applications ranging from flow into water treatment plants, storm and sanitary sewer systems, and effluent from water resource recovery, to industrial discharge and irrigation channels.
