Hot Flow Switch Safety Measure Liquid Temperature To Determine Flow Rate Changes


Measuring Principle Of Hot Flow Switch


Thermal flow switches are designed based on the principle that the temperature change of the probe produces a difference. A heating element and two thermal sensors are built into the probe, which are in contact with the medium. When the thermal flow switch is working, the heating element emits constant heat. When there is no medium flowing in the pipeline, the heat received by the thermal sensor is a constant value. When there is a medium flowing, the heat received by the thermal sensor will follow. The flow rate of the medium changes, and the thermal sensor converts the temperature difference signal into an electrical signal. When the flow rate reaches a certain set point, the thermal flow switch outputs a switch signal.

Overview Of Hot Flow Switch


Thermal flow switches can be used to monitor the flow rate of fluid in a pipeline, monitor interruptions, or prevent idling of pumps. Thermal flow switches are widely used in various industries where it is necessary to monitor the fluid flow rate in the pipeline or protect important equipment when the liquid flow fails, such as protecting water pumps, monitoring lubricating oil circuits, refrigeration and heating circuits, monitoring pipeline ruptures, monitoring leaks, etc. .


The thermal flow switch measures the temperature of the liquid to determine the change in flow rate. When the liquid flows through the end of the sensor, the temperature decrease is proportional to the flow rate. When the flow rate change reaches the user set point, the switch state will change to display traffic situation.
