Overview

The electromagnetic flow meter consists of two parts: an electromagnetic flow sensor and an electromagnetic flow converter. It is used for measuring the instantaneous flow rate and volumetric flow rate of conductive liquids and slurry.

Electromagnetic flowmeters can be categorized into two types: split-type and integrated-type. In split-type electromagnetic flowmeters, the sensor and converter are separate structures, with the sensor mounted on the pipeline and the converter installable within 200 meters from the sensor. Integrated-type electromagnetic flowmeters integrate the converter onto the sensor, forming a single unit. Once the converter is powered with 24VDC or 220V50Hz, it supplies a low-frequency tri-state constant excitation current to the sensor via the excitation cable. As the conductive fluid passes through the sensor, the flow signal generated is transmitted to the converter via the signal cable, where it is processed to display instantaneous and cumulative flow rates. The converter also outputs a standard 4-20mADC, 0-2KHz signal and can communicate with a supervisory computer via the 485 interface.
