Quick Details
Specifications
FGS thermal conductivity flow switch monitors the liquid flow in the pipeline in real time, provides switching output, and 6 LEDs display the fluid status in real time, which can realize the following monitoring functions: medium reduction/increase flow rate; medium presence/absence; medium flow/static. It is suitable for monitoring the fluid velocity and flow cutoff in the pipeline to prevent 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.
the working principle of FGS flow switch:
FGS thermal conductivity flow switch is designed based on the principle of heat exchange.
the probe has a built-in heating module and a heat-sensing module. the heat conduction of the flow switch is closely related to the flow rate of the medium.
during measurement, the heating module emits heat according to the working principle of the thermal conductivity flow switch. If there is no medium flowing in the pipe, the heat received by the thermal module is a fixed value; when there is a medium flowing, the heat received by the thermal module It will change with the flow rate of the medium, and the thermal module converts the temperature difference signal into an electrical signal, and then converts it into a corresponding standard analog signal or contact signal output through the processor, and the flow switch uses this signal to control the flow rate of the medium. Display and control.
Its characteristics:
the anti-fouling 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 fully waterproof shell design is suitable for a large range of pipe diameters, and the set point can be adjusted arbitrarily.
Effectively prevent entanglement.
FGS thermal flow switch can easily set the flow alarm node, unscrew the protective screw, and use the provided screwdriver to adjust the setting knob to set the flow alarm point. for the flow switch whose output form is P N P, N P N and relay, the meaning of its LED indication is as follows:
- Red light on Flow rate below set point (transistor not conducting/relay not operating)
- Yellow light on Flow rate equal to or higher than set point (transistor on/relay action)
- Yellow and green lights the extent to which the flow rate exceeds the set point (green lights 1, 2, 3 or 4 are on together with the yellow lights)
