Open Channel ultrasonic flow meter is designed to measure the fluid velocity and flow of liquid of river, channel, lake or other opened water areas.
The ULFM 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 ULFM series OCM can be widely applied to the environmental protection, water treatment, irrigation, chemical, and other industries.
