Installation location precautions


The installation location is chosen according to the following requirements, ensuring

the stable and continuous operation of instruments.
Atmosphere temperature: avoid large temperature change and sunshine, if some thermal

radiation in the installation location, the thermal insulation and ventilation should be applied.
Air condition: avoid strongly corrosion and explosive gas in the installation location
(non-explode-resistant instrument).

Change adapter direction


It is not recommended to change the adapter direction by users, if it is necessary to

change, pleasecontact service center.

?


Product application scope


The insert-type electromagnetic flow-meter is composed of sensors and adapter, using

for measuring conductive liquid. During measurement, conductivity is required to be

more than 5μ s/cm, and water, sewage, acid and alkali and so on could be measured.

Sensor structure


The sensor is composed of measurement detector, installation flange and wire box

(separate type)
Adapter
Flange
Base
and so on. The sensor outline is in cylinder shape with installation flange, inside which

the excitation winding used for exciting, magnet-conductive winding and two electrodes

of magnet-conductive core, contacting liquid, are installed.

Lining material | Main Performance | Applied Scope |
PTFE | # # Have the most stable chemical properties in plastics, and resist 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, liquid fluorine, liquid oxygen and ozone. # Low abrasion resistance 3.Low negative pressure resistance | 1. -25℃－140℃ 2. Strong corrosion medium, like strong acid and alkali. 3.Healthcare medium |
CR | Oil proof, solvent resistance, oxidatite resistance and the resist the erosion of common medium like acid, alkali, salt, etc | 1.<80℃ 2.be able to measure sewage and mud |
PU | # # Very good abrasive resistance, flexibility 2. Low acid and alkali resistance | 1. <65℃ 2. Neutral strong abrasion resistance medium |
Hard Rubber | # # Good resistance to room temperature, hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide # Avoid strong oxidants | 1.<80℃ 2.General acid, alkali, salt solution |
PFA | # # can be used for most corrosive medium like acids, alkalis, and strong oxidant. # 2.high material strength, resistance to aging, better than PTFE,EFP in high temperature # Injection molding for higher negative pressure | 1.40－180℃ # # strong corrosion medium, like strong acid and alkali # Healthcare medium |
FEP(F46) | # # hydrophobicity and non-viscous # Corrosion resistance is inferior to PFA # Negative pressure | 1.40－180℃ # # strong corrosion medium, like strong acid and alkali # Healthcare medium ? |
