High Accuracy Electromagnetic Flow Meter Low Conductivity Measurement


1. Introduction

MLF electromagnetic flowmeter is based on Faraday's law of electromagnetic induction and consists of sensors and converters. Used to measure the conductivity of a liquid or solid. Generally, its conductivity should be greater than 5μS/cm (the conductivity of tap water, raw water is about 100~500μS/cm). it can also be used to measure various media such as acid, alkali, brine, pulp or pulp and other medium. But these medium can not contain a large number of magnetic substances and bubbles.

MLF electromagnetic flowmeter is an instrument to measure liquid fluidity. Widely used in metallurgy, chemical, paper, environmental protection, petroleum, textile, food, urban management, water plants and other industries of flow measurement.


2. Features

MLF electromagnetic flowmeter is explosion-proof design.

Function of low conductivity measurement.

There are nine languages(Chinese, English, Korean, Polish, Turkish, French and Portuguese languages) options to meet the needs of different customers.

It has the function of self-regulation and self-examination.

Different outputs are optional: Hart,RS485 Profibus,4-20mA, frequency, pulse.

4. Selection of Electrode Materials

Electrode MaterialMain Performance
316L

Good corrosion resistance to nitric acid, less than 5% corrosion of sulfuric acid, acetic acid, alkaline liquid, sulfite, seawater and acetic acid under certain pressure at room temperature, and can be widely used in petrochemical urea, vinylon and so on

Hb

Good resistance to hydrochloric acid with concentration lower than boiling point and corrosion of non-oxidizing acid, alkali, sulfuric acid, phosphoric acid, hydrofluoric acid and organic acid.

Hc

Corrosion of oxidizing acids, such as nitric acid, mixed acids. A mixture of chromic acid and sulfuric acid, oxidized salts, such as Fe3,Q3, and some other oxidants, such as a mixture of hypochlorite solution and seawater above normal temperature.

TiResistance the corrosion of seawater, various chlorides, hypochlorite, oxidizing acid(including fuming nitric acid), and organic acid or alkali, but don't be resistance to the corrosion of pure reducint acid(like sulfuric acid, hydrochloric acid). But if acid includes oxidants(like nitric acid, Fe3+, Q3+), the corrosion resistance will decrease.
TaGood corrosion resistance similar to glass. Resistance to the corrosion of chemical medium(including hydrochloric acid and fumiing sulfuric acid), but can not be used for sodium hydromide fluid.
Pt-IrHave good corrosion resistance of all acid, and can be resistance to the corrosion of alkali, all salt except aqua regia, ammonium slat and few other medium
Tungsten CarbideFor pulp and sewage, good resistance to solid particle interference.
