flow switch is the product of two decades knowledge in thermal power station, fertilizer & chemical industries. Flow switch is the target type unit that works on the magnetic principle of attraction. As the flow causes the flapper to deflect the magnet moves closer to or further away from the switch causing the reed switch to actuate. Switching action is determined by flow & not by pressure. The unique features of reed switch technique is adapted unique design, magnetic switching and uncompromised quality have resulted in unparallel reliability.
