Digital Electromagnetic Water Flowmeter,
Magnetic Sewage Water Flow Meter Model: 4800
Our flow meter line :
Specification of Electromagnetic Flow meter
4800E Electromagnetic Flowmeter is fully comprehensive (all intelligence) which is developed in using the advanced technology from domestic and foreign countries and consisted of 4800-type water flow meter and 4800-type smart converter supporting.
It is widely used in water (tap water, industrial water, and sewage treatment) metallurgy, chemical, textile, food, paper, power, pharmaceutical and other industrial areas. It applies to measure (is fit for the measurement of ) the volume flow of conductive medium including the acid, alkali, salt solution, slurry, pulp, paper pulp, waste water.
I.Selection suitable Electromagnetic Flow meter
Do not have to choose the most expensive, choose the right is economical and durable
Electromagnetic Flowmeter form of the structure is divided into separate type and integrated two types. Selected sub-body is still the basic norms of a body that is: when the meter in cluttered environment conditions (such as high temperature fluid, the presence of explosive gases and intense sensation of occasions and have water may engulf the occasion, etc.) use, should be used in remote version structure. Under good environmental conditions using a body electromagnetic flowmeter.

1. Environment for installation should be dry and wind, avoid shining from sun, temperature of environment is not
more than 40 degC.
2. It should be far away from high magnetic place o electric equipment. Such as large transformer, welding
machines.
3. It is should be far away from the place including NH3, acid fog.
4. Pipe is installation should be filled with measuring medium. it cannot be empty.
5. The instrument should not be installed inside pipe with negative pressure avoiding lining shedding.
