流量开关（Flow switch） Thermal conductivity FS-T thermal flow switch flow indicator is designed based on the principle of heat exchange, probe the built-in heating module and the heat sensing module, heat flow indicator and the measured velocity is closely related to, if not the medium flow pipe, heat heat received sense module is a fixed value, and when the fluid medium through the flow indicator probe, the heat sensing module receives heat and change the flow velocity of medium, the heat sensing module the temperature signal into electrical signal, then the signal processor output into a 4 ~ 20mA signal and the corresponding flow or set. The thermal flow indicator will be integrated flow probe and signal processor integration, six LED lights provide flow trend display, switching value can easily through the front panel of the potentiometer adjustment screw protection, and can provide a transistor, relay and analog output form. The Gems piston type flow switch works on a fluid passage inside the housing with a piston with a permanent magnet inside. When the piston is pushed by the pressure difference caused by the fluid flow, the magnetic piston will switch the sealing reed of the equipment (the sealing reed can be SPST or SPDT, which is related to the model of the product). The diameter of the piston determines the starting flow. When the flow is reduced, the stainless steel spring pushes the piston back. When the reed switch is started, it can be transmitted by remote warning or indication. Or you can integrate it into automatic control In system. Working principle： Thermal conductivity flowmeter is designed based on the principle of heat exchange. The probe is equipped with a heating module and a heat sensitive module. The heat of the indicator is closely related to the flow velocity of the fluid on the side. If there is no medium flow pipe, heat heat received sense module is a fixed value, and when the fluid medium flows through the flow indicator probe, sense recei
