DN200 Digital Magnetic Flow Meter Accuracy Carbon Steel Remote Type
1. Introduction
MLF electromagnetic flowmeter works according to Faraday's law of
electromagnetic induction, and is composed of sensors and
converters. Used to measure the conductivity of liquid or solid. In
general, its conductivity should be greater than 5μs/cm (tap water
and raw water conductivity is about 100 ~ 500μs/cm), and it can
also be used to measure acid, alkali, brine, pulp or pulp and other
media. However, these media cannot contain a large amount of
magnetic substances and bubbles.

3. Selection of Liner Material
| Liner Material | Main Performance | Application |
| PTFE | 1. Have the most stable chemical properties in plastic and
resistance to boiling hydrochlor and sulfuric acid, nitric acid
aqua regia, strong alkali, and all kinds of organic solvents, but
can not resist the corrosion of chlorine trifluoride, high
temperature nitrogen trifluoride, liquid fluorine, liquid oxygen
and ozone. 2. Low abrasion resistance. 3. Low negative pressure resistance | 1. -25~140ºC 2. Strong corrosion medium, like strong acid and alkali 3. Healthcare medium |
| CR | Oil proof, solvent resistance, oxidatite resistance and the
resistance to the erosion of common medium like acid, alkali, salt,
etc. | 1. <80ºC 2. Be able to measure sewage and mud |
| PU | 1. Very good abrasive resistance, flexibility. 2. Low acid and alkali resistance. | 1. <65ºC 2. Neutral strong abrasion resistance medium |
| Hard Rubber | 1. Good resistance to room temperature, hydrochloric acid, acetic
acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid,
sodium hydroxide, potassium hydroxide 2. Avoid strong oxidants | 1. <80ºC 2. General acid, alkali, salt solution |
| PFA | 1. Can be used for most corrosive medium like acides, alkalis, and
strong oxidant. 2. High material strength, resistance to aging, better than PTFE,
EFP in high temperature 3. Injection molding for higher negative pressure | 1. 40~180ºC 2. Strong corrosion medium, like strong acid and alkali 3. Healthcare mdium |
| FEP(F46) | 1. Hydrophobicity and non-viscous 2. Corrosion resistance is inferior to PFA 3. Negative pressure | 1. 40~180ºC 2. Strong corrosion medium, like strong acid and alkali 3. Healthcare mdium |
