1-9 Basher Open Channel Flow ChannelDetailed product description：

The 1-9 Bachel open channel flow channel from tank 1-9 can be used in conjunction with any national standard model of open channel to convert the flow rate inside the channel into the level of liquid. Measure the flow rate of water in an open channel. The flow rate of irrigation channels, sewage ditches, and urban sewers.

Precautions
The centerline should coincide with the centerline of the channel to prevent water flow from deviating into the Bacher trough.  
After the Bacher trough is filled with water, the flow state of the water should be free flowing. The submergence degree of the Bacher trough should be less than the specified critical submergence degree.  
There should be a straight section upstream that is greater than 5 times the width of the channel, so that the water flow can smoothly enter the Bacher trough. There is no lateral deviation or the impact force formed by the slope of the channel.  
The Bacher groove should be securely installed on the channel. The connection with the side walls and bottom of the channel should be tight and not leak water. Make all the water flow through the measuring part of the Bacher trough. The measuring part of the Bacher trough is the throat section inside the trough.
