Insertion Impeller Flow Sensor-SN51C

Product introduction

SN51C series insertion impeller flow sensor and an intelligent flow switch, is a compact flow sensor, with small size, easy to set up and other advantages, built-in intelligent circuitry, can be set arbitrarily flow upper and lower limits of the alarm value can be set remotely to monitor the real-time flow conditions, the full range of parameters on-site arbitrary setup, and its impeller measuring medium through the flow through the sensor intelligent circuitry to process arbitrary programming.
Hall-type pulse output, open collector PNP/NPN, strong driving ability.
-High chemical resistance
-IP65 protection class, suitable for harsh field environment.
-Plug-in type for easy installation
-Good stability, strong anti-interference ability
-Good reliability, maintenance-free
