Product Description

Product description
Thermal flow switch,based on the thermal principle, contains two resistors in a closed probe, one of which is heated as a detection resistor, and the other is not heated as a reference resistor. When the medium is flow, the heat on the heating resistor is taken away, the resistance value is changed, and the difference between the two resistances is used as the basis for judging the flow rate.The probe adopts anti-scaling coating, which can effectively prevent the adhesion of scale, rust and other dirt in the pipeline, with stronger anti-fouling ability and more stable work.

Main Features
This series of thermal conductivity type flow switches can monitor the liquid flow in the pipeline in real time. One model is used
for a variety of pipe diameter requirements, provides switch output, and uses 6 LEDs to display the fluid flow rate status in real time,
which is widely used It is used in petrochemical, electric power, metallurgy, steel mills, food processing, water treatment, battery factories and other industries. Gas-liquid dual-purpose type, can be used
in pneumatic and hydraulic systems,
can be used for circulating water,
cutting fluid and lubricating oil cut-off monitoring, and pump idling protection.
