Tips for installing air flow switch

The flow switch needs to be installed on the straight section of the pipe or air duct
It is necessary to ensure that there are long enough straight pipes before and after the installation position of the flow switch. The length of the normal straight pipe should be greater than 10 times the diameter of the pipe.
Avoid installing or wiring flow switches near elbows, other fittings, valves, drains, narrow or wide pipe sections, and any other features that may cause significant fluctuations in flow through the area.
