FGS thermal diffusion flow switch can monitor the liquid flow in the pipeline in real time, provide switch output, and use 6 LEDs to display the fluid flow rate status in real time, which can realize the following monitoring functions: medium flow, reduce/increase flow rate; medium Presence/absence; medium flow/still; monitoring the fluid flow rate in the pipeline, monitoring the interruption of flow or preventing the idling of the pump. It is widely used in petrochemical, electric power, metallurgy, steel mills, papermaking, food processing, water treatment, battery factories and other industries.
Working principle of FGS flow switch:
FGS thermal conductivity flow switch is designed based on the principle of heat exchange.
The probe has built-in heating module and heat sensing module. The heat conduction of the flow switch is closely related to the flow rate of the medium,
During measurement, the heat is generated by the heating module according to the working principle of the thermal conductivity flow switch. If there is no medium flow in the pipeline, the heat received by the heat sensing module is a fixed value; When a medium flows, the heat received by the heat sensing module will change with the flow rate of the medium. The heat sensing module converts the temperature difference signal into an electrical signal, and then converts it into the corresponding standard analog signal or contact signal output through the processor. The flow switch displays and controls the flow rate of the medium through this signal.
Its characteristics:
The anti scaling coating of the probe can effectively prevent the adhesion of scale, rust and other dirt in the pipeline, and has stronger anti fouling ability.
The full waterproof shell design is applicable to a wide range of pipe diameters. The set point can be adjusted arbitrarily. The high-pressure type can withstand pressure up to 60MPa. The indicator light directly displays the flow change.Effectively prevent entanglement.
