Ultrasonic Open Drain/Channel Flowmeter River Water Flow Meter 4-20mA RS485(Optional) Liquid Sensor Non-Contact Transmitter

Product Introduction:

The ultrasonic open channel flow meter with weir and flume which used together for measured the flow in the open channels. Mainly application is the outfall of sewage plant and the sewage of enterprises, city sewer and irrigation channels.

The instrument produced by our company uses ultrasonic waves through the air, non-contact method to measure. Compare with contact instrument, it has higher reliability and durability in the condition of sticky dirt.

Product working principle:

The direct measurement of this series is liquid height of channel and flume. For flow measurement in open channels, installation of weir and flume on the channel, it makes the flow change into level. After measured the level in the weir and flume, then calculate the flow according to corresponding connection of level- flow.

Flow measurement accuracy

Standard weir tank is 1 to 5% (weir tank and channels meet the national standardrequirement)

Non-standard weir tank is 10 to 30 percent.
