Explosion-proof electronic turbine flow sensor SN-51E

PREV: Explosion-proof micro circular gear flow sensor SN-54E
NEXT: Flow, temperature, pressure integrated switch sensor-SN560

Product introduction

SN-51E 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, can be set arbitrarily flow upper and lower limits of the alarm value can be remotely monitored the real-time flow conditions, the full range of parameters on-site any setup, and its turbine measurement medium through the flow through the sensor intelligent circuitry to process the arbitrary programming.
-Protection level: 1P67
Explosion-proof marking bit ExedIICT6
-Applicable to the measurement of low-viscosity media, such as water, diesel, petrol.
-Increase the role of upper and lower limit alarm on the basis of the traditional turbine flowmeter.
