Product Description

FS-402 Flow switches used in Tank-less water heater
Description:
    Tank-less Water Heater heats water instantly to any adjustable temperature, Cold water enters at the bottom and travels through a flow switch which activates the heating unit when the power switch is on. When incoming water exits the flow switch, it comes in contact with stainless steel heating elements which efficiently transfer energy to heat the water.
The flow switches is with compact structure, good quality, made of SUS304 material, with G1/2" mounting threads, the setting rating can be selected from 1.2 LPM to 2.0LPM and used in tank-less water heater.
The principle is that when cold water travels through the flow switches, the piston of flow switches in housing pipe is moved, the magnet sealed in piston operate the reed switches from open to close (or from close to open ), output a switches signal, the reed switches close or open the electric circuit.
    The flow switches is used in many industry equipment such as Compressors, Heat Exchangers, Turbines, Engine, Boilers, Chillers, Valves, Pumps, Regulators.
