1. Detection of flows of at least 1.5L ~ 2.0L / min, and allows flows of up to 20L / min.
2. Product designed without springs, but with the force of magnet repulsion: it is safe and reliable.
3. It can be applied to control electric water heater of rapid heating, which can detect water supply, cut off and turn off the water. The effect of energy saving is remarkable.
4, Can operate more than 10 million times, with long life and reliability.

Operating principle:
5. ATTENTION: DO NOT TRY TO CONTROL A MOTOR, PUMP, SOLENOID, BALLAST OR ANY INDUCTIVE LOAD DIRECTLY! -- If you need to control inductive or higher power loads, you must use a current carrying relay, contactor or TRIAC. A direct connection can cause
The water flow switch is a very important component in the instant electric water heater. When the water inlet flows more than 1.75L / min, the circuit turns on and the electric water heater starts to heat up, when the water inlet stops, the water heater stops working.

The disadvantage of the traditional spring water flow switch (mechanical switch) is that a large flow is required to activate the switch.

The magnetic floating water flow switch controls the on / off of the blade switch through the magnet to perform passive contactless work, which is safe and reliable.

Application of the product:

Electric water heater of instant heating type, electric water heater of heat storage type, can perform water supply and electric power supply, water supply detection.

Its structure and operating principle is based on a magnetic ring on a piston. When it is working, the water pressure pushes the piston. When the internal magnetic ring of the piston is pushed to the Reed switch position, the reed switch generates a Dry-contact signal. These switches have a stable performance and are widely used in various types of equipment.
