Installation Precautions
1) Please ensure that the measuring pipe is full of water level, otherwise it will cause measurement errors.
2)Can be installed horizontally or vertically.
3) When installing the flow sensor, please keep an appropriate length of straight pipe before and after the flow sensor to prevent eddy currents. (The upstream distance must exceed 10 times DN; the downstream distance must exceed 3 times DN)
4) Please install an appropriate filter in front of the flow sensor to prevent foreign matter from damaging the rotor.
5) Do not flush the pipeline after the flow sensor is installed, otherwise the ceramic shaft may be damaged.
