The flow switch can be installed in every position far from elbows or throttlings, with arrow on flow direction. If pipe is vertical, recalibrate range to balance paddle weight. If the device is downwards mounted, take care to slags and apply it in a straight pipe that is far from filters, valves, etc., with length at least 5 times the diameter of pipe upstream and downstream the unit.
