The ULFM series Ultrasonic Open Channel Flow Meter 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 ULFM series Open Channel Flow meter can be widely applied to the environmental protection, water treatment, irrigation, chemical, and other industries. We are open channel flow meter manufactures to provide robust and cheap open channel flow meter.
