Open Channel Flowmeter Series UDC
|
|
|
|
The UDC series is a remote version ultrasonic open channel flow meters (O.C.M.). It consists of two elements, a wall mounted host, which has a display and an integral keypad for programming, and a probe, which must be mounted directly above the surface to be monitored. Both of the host and the probe are plastic leak-proof structure.
|
|
|
The UDC series (O.C.M.) can be widely applied to the environmental protection, water treatment, irrigation, chemical, and other industries.
BENEFITS
l High detection accuracy, the flow meter measurement changes with 1mm, the accuracy of change in level is 1 mm;
l Suitable for a variety of weirs and flumes, Parshall flumes (ISO), Right-angle triangle weir, Rectangular weir;
l Displays flow rate in L/S or M3/h;
l Excellent anti-interference capability;
l Clear display with enhanced 14 digit two line backlit LCD;
l The cable length between probe and host up to 1000m;
l The probe with leak-proof structure and IP68 protect grade;
l Chemically resistant probe materials for maximum application flexibility;
l Provided 4-20mA output and RS485 serial communication (MODBUS-RTU) output;
l Provided programmable 6 relays at most for alarms, and The pulse output for cumulative flow rate.
l Three button for programming or remote control for easy configuration and operation ( opt.);
UDC series Remote ultrasonic level meter, the use of imported host shell, compact and easy to install, commonly functional, economical and practical is preferred.
