Turbine flow and temperature integrated sensor-SN52B

Product introduction

SN52B series electronic turbine 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 parameters on-site arbitrary setup, and its turbine measurement medium through the flow through the sensor intelligent circuitry processed by arbitrary programming.
-Protection level: 1P65
Suitable for measuring low-viscosity media, such as water, diesel, gasoline.
-In the traditional turbine flowmeter based on the addition of the upper and lower limits of the alarm function.
