Integrated Type Electromagnetic Flow Meter SS Material with Liner
Material of Rubber / PTFE / PFA / FEP / F46
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. Quick Details
MLF electromagnetic flowmeter is explosion-proof design.
Function of low conductivity measurement.
There are nine language 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 Material | Main 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 | Resistant to the corrosion of oxidizing acid, such as nitric acid
and mixed acid. The mixture of chromic acid and sulfuric acid,
oxidized salts, such as Fe3+, Q3+, and other oxidants, such as the
mixture of hypochlorite solution and seawater at higher than normal
temperature. |
| Ti | It is resistant to corrosion by sea water, various chlorides,
hypochlorites, oxidizing acids (including fuming nitric acid),
organic acids or alkalis, but not resistant to corrosion by pure
reducing acids (such as sulfuric acid and hydrochloric acid).
However, if the acid contains oxidants (such as nitric acid, Fe3+,
Q3+), the corrosion resistance will be reduced. |
| Ta | Good 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-Ir | Have 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 Carbide | For pulp and sewage, good resistance to solid particle
interference. |
