E-mag Micro-flow Magnetic Flow Meter

E-mag Micro-flow Magnetic Flow Meter

Kaifeng Instrument E-mag series electromagnetic flow meters (or magnetic flow meters) are comprised of a converter and sensor. Then sensor is placed inline, and the converter picks up the voltage signals generated by the fluid passing through the sens…

Product Overviews

An all-welded structure provides a hermetic seal that protects against moisture and other contaminants. The sealed housing ensures maximum sensor reliability by protecting all internal components and wiring from even the most aggressive environments.

 With 5-section correction calculation, the E-mag C converter provides highly accurate and stable measurements in even the most critical applications. The size of the sensor can be as small as 3mm to 15mm to match the pipe size of the small flow applications.

Features And Functions

● Small and compact design of the sensor for small size pipe line measurements

● A fully welded sensor housing provides a hermetic seal, ensure reliability in the harshest environments with an all-welded sensor housing

● Minimize maintenance and repair with an obstructionless design featuring no moving parts

● Robust, fully welded construction designed to withstand sustained vibration

● Easy-to-read LCD display with backlight is visible in low light environments and in direct sunlight

● Intuitive configuration and accessibility with an easy-to-use Local Operator Interface
