Precautions for installation and maintenance of water flow indicator

Release time:


1. The water flow indicator must be installed on the pipe diameter with the length of the front and rear straight pipe sections not less than 5 times. The blade installation direction should be consistent with the arrow direction and the water flow direction.
2. The water flow indicator should be installed horizontally with the pipeline, and it should be ensured that the blades do not collide with the inner wall of the pipeline.
3. When the saddle type water flow indicator is installed and inserted into the pipeline, the sensing blade should be rolled into a cylindrical shape. The removal should also be pulled out in this way.
4. The water flow indicator should be checked once every six months after installation.
