Description
Applacation:
The LSS-10Q ultrasonic open channel flowmeter is used in conjunction with the water measuring weir to measure the flow of water in the open channel. It is mainly used to measure the flow of sewage plants, sewage outlets of enterprise liquid units, and urban sewers. Because this instrument uses ultrasonic waves to pass through the air, it measures in a non-contact way.
Features:
1. To select the type of weir and flume for measuring water, it is necessary to consider the size of the flow in the channel, the flow state of the water in the channel, and whether it can form free flow.
2. When the flow rate is less than 40L/s, a right-angle triangular weir should generally be selected; if the flow rate is greater than 40L/s, a Parshall flume should generally be selected; if the flow rate is greater than 40L/s, and the water level drop in the channel is large, a rectangular weir can be selected.
3. If conditions permit, it is best to choose Parshall trough. The water level-flow relationship of the Parshall flume is calibrated by experiments, and the requirements for upstream traveling flume conditions are relatively weak.
