Electromagnetic Flowmeter NM200 series

Product Overview

The NM200 series electromagnetic flowmeter is a major flow meter consisting of a sensor and a converter. It operates based on Faraday’s law of electromagnetic induction and is used to measure conductive liquids or two-phase media. Its conductivity is generally required to be greater than 5 uS/cm (the original conductivity of tap water is about 100-500uS/cm). It can be used to measure various acid, alkali, salt solutions, pulp, slurry and other media, but the media should not contain a lot of ferromagnetic substances and a large number of bubbles.

Applicable fields

Widely used in industrial sectors and cities such as petroleum, chemical, metallurgical, textile, papermaking, environmental protection, food, etc
Fluid measurement in fields such as political management and water conservancy construction.

Product Features

Measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
-The sensor with unobstructed flow components, no pressure loss, and low requirements for straight pipe sections can be equipped with a grounding electrode to achieve good instrument grounding;
-It has the function of measuring positive/negative bidirectional flow;
-The converter adopts a liquid crystal backlight display, which makes it easy to read under direct sunlight or in a dark room. The converter can simultaneously display the volume flow percentage, actual flow rate, and cumulative flow rate;
-Installed on the pipe, the display screen rotates ≤ 90 ° with the standard (type) to improve the visibility of the integrated flowmeter;
The converter has functions such as self diagnostic alarm output, empty load detection alarm output, flow upper and lower limit alarm output, and two-stage flow value output.
