ultrasonic open channel flow meter for parshall flume/rectangular weir/triangular weir
open channel ultraosnic flow meter
Description
Ultrasonic open channel flow meter with a weir tank with the use of measuring the flow of water in the open
channel. Mainly used to measure the waste water treatment plant, sewage outfall enterprises, the city sewer
and water conservancy in the flow channels.
As the Company through the air using ultrasonic instruments to non-contact measurement method. Therefore,
under dirt, corrosive liquid condition, than contact type instrument, with higher reliability and durability.
