Slurry Electromagnetic Flow Meter

规格型号：

INTRODUCTION

Magnetic flow meter is ideal for conductive liquids. It is composed of a sensor and an intelligent conversion part. Water flowmeter can measure the volume flow of various conductive liquids. The measured media include acid, alkali, salt and paper pulp, mud, waste water, sea water, and solid-liquid liquids. In addition, the sensor adopts an integral sealed structure, and the measuring tube and the shell are integrated, which is moisture-proof and waterproof, and is suitable for underground or humid environment installation.

FEATURES

◆ Measurements are not affected by fluid density, viscosity, temperature, pressure and conductivit.

◆ No obstacles in the measuring tube, no pressure loss, low requirements for straight pipe section.

◆ The LCD backlight type converter can be easily displayed and read in the sun or in a dark room.

◆ Flow meter with bidirectional measurement system, built-in three totalizers: positive total, reverse total and total difference.

◆ It has various forms of output: current 4-20mA, pulse, rs-485, HART.

◆ The converter has self-diagnosis alarm output, no-load detection alarm output, flow upper and lower limit alarm, batch control (need to be customized)

and other alarm output functions.
