Paddle flow switch is also called the booster pump flow switch, it adopts magnetron device sensing on-off to control the water pump.

This type paddle flow switch is mainly applicable to household water pressurization of the low pressure region. In particular, the start of shower and the automatic cycle of solar water heater.

Operating principle:

Open water equipment, water flow in the piping, the flow impulse sensing door along the shaft rotation rotating as the flow direction of water flow, magnetic control device together with the shaft rotation, rotate to a certain position, the trigger sensing element switch and it is turned on, domestic pipeline booster pump to be started.

When water flow is closed, the sensing door drives the shaft and magnetic control device rotating to certain position. If the induction fail in sensing, the switch off, and then the booster pump stops running.
