Brief Introduction

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.

product usage

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.

Product introduction and advantages

1.Open channel ultrasonic flow meter is designed to measure the fluid velocity and flow of liquid of river, channel, lake and opened water areas. The transducers are a non-contacting, clamp-on type, which will provide benefits of non- fouling operation and easy installation.

2.It employs a patent balanced lower voltage multi-pulse igniting circuit which increases the anti-interference ability magnificently so that the flow meter will work properly even in demanding industrial environments such as those with power frequency transverter working nearby.Optimization of the intelligent adaptive signal processing, the user without any adjustment circuit.

3.Other outstanding features is the signal receiving circuits feature self-adapting performance so as to ensure that the user can easily operate the instrument without any adjustment.
