MEASURING PRINCIPLE
INSTALLATION
a. Installation in still water (deep well, pool, liquid tank)
b. installation in moving water
Method 1: When the medium fluctuates greatly, a steel pipe is inserted into the water channel, and the internal strength is about 4.5, and a small number of holes are formed at different heights on the opposite side of the water flow direction, so that the flowing water enters the pipe.
Method 2: When the medium fluctuates greatly, it is also possible to filter the sediment by adding a damping device and eliminate the adverse effects of dynamic pressure and waves to ensure measurement accuracy.
