SN-51F Series Explosion-proof Impeller Flow Sensor

Product introduction

SN-51F series explosion-proof impeller flow sensor and an intelligent flow switch, is a compact flow sensor, with a small size, easy to set up and other advantages, built-in intelligent circuitry, you can arbitrarily set the flow upper and lower limits of the alarm value, you can remotely monitor the real-time flow conditions, the full range of parameters on-site arbitrary settings, and its impeller measuring medium through the flow through the sensor intelligent circuitry to process any programming. Hall-type pulse output, open collector PNP/NPN, strong driving ability
-Highly resistant to chemical corrosion characteristics
-Explosion-proof type easy to install
-Good stability, strong anti-interference ability
└Good reliability, maintenance-free
