Product Overview

OVERVIEW

 New 

FSH-10 economical electronic flow switch



Widely applicable to pipelinesSwitch,CloggedCut-off alarm, pump idling alarmWait for many occasions


FSH-10 economical electronic flow switch is usedIt is designed based on the principle of difference caused by temperature changes of the probe.. economicalLow cost, can be used forpipes of different sizes, Measurable low flow rate, Liquids, gasesall measurable, and other features.Low installation requirements, high pressure resistant,Resistant to slight corrosion,Suitable for variousPipe no-flow protection, leak alarm, dry-run pump alarm or control.




Features

FEATURES

FSH-10 economical electronic flow switchIs to useProbeTemperature changes produceDifferenceDesigned based on the principle. A heating sensor and two thermal sensors are built into the probe and are in contact with the medium. When the thermal flow switch is working, the heating sensor emits constant heat. When there is no medium flowing in the pipe, the heat received by the thermal sensor is a constant value. When there is medium flowing,Feeling hotThe heat received by the sensor will change with the flow rate of the medium. The thermal sensor converts the temperature difference signal into an electrical signal.Flow rateWhen reaching a certain set point, the thermal flow switch outputs a switching signal.

 Application Areas:

■ FSH-10 economical electronic flow switch is mainly used to monitor the flow rate of fluid in pipelines, monitor flow interruptions or prevent idling of pumps. Thermal flow switches are widely used in various industries where it is necessary to monitor the flow rate of fluids in pipelines or protect important equipment when liquid flow fails, such as protecting water pumps, monitoring lubricating oil circuits, refrigeration and heating circuits, monitoring pipeline ruptures, monitoring leaks, etc.
