Product Description

PNP NPN relay oil and water thermal flow switch  

1.Overview

Flow switch is a kind of measurement instrument which could real-time monitor the liquid and air flow in the pipeline, and output signal at the same time.This product adopts all metal case, no moving parts, the switch quantity can be continuously adjustable, pressure loss is small, compact structure, a plurality of LED real time display of flow state and the state of the switch. Easy installation, suitable for a variety of diameter of product requirements, can be used to monitor the fluid in the pipeline flow, stop idling protection monitoring or prevent pump. Widely used in the hydro-power industry, industrial hydraulics of flow monitoring.
