Overview
The waterway that flows in a non full pipe state is called an open channel. The application of open channel flow meters includes urban water supply channels, cooling water intake and drainage channels for thermal power plants, sewage treatment inflow and discharge channels, industrial and mining wastewater discharge channels, as well as water conservancy engineering and agricultural irrigation channels. Our company specializes in producing various specifications of Bacher troughs for use with open channel flow meters.

Structural schematic diagram explanation
Symbol description: b is the width of the throat, B1 is the width of the inlet channel, B2 is the width of the outlet channel, L is the length of the throat, L1 is the contraction section, L2 is the diffusion section. The construction and use conditions of the weir groove are: B>=b, h/p<2.5, h>0.03m, p>0.1m. The circular position is the schematic diagram of the installation position of the probe
Installation precautions
The size of j is related to the installation of the channel, please make the decision according to the on-site situation.
2. The centerline of the Bacher trough 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.
4. There should be a straight section upstream of the Bacher trough that is greater than 5 times the width of the channel, so that the water flow can enter the Bacher trough smoothly. There is no lateral deviation or the impact force formed by the slope of the channel.
5. 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.
