Electromagnetic Flow Meter for Water Flow Rate Measurement with 1 Inch / 3 Inch And So On
1. Introduction
The MLF electromagnetic flowmeter works according to Faraday's law of electromagnetic induction and consists of a sensor and a transducer. Used to measure the conductivity of a liquid or solid. In general, its conductivity should be greater than 5μS/cm (tap water, raw water conductivity of about 100 ~ 500μS/cm), can also be used to measure acid, alkali, salt water, pulp or pulp and other media. However, these media should not contain large amounts of magnetic material and air bubbles.
MLF electromagnetic flowmeter is a kind of instrument to measure liquid fluidity. Widely used in metallurgy, chemical industry, paper making, environmental protection, petroleum, textile, food, urban management, water plant and other industries flow measurement.
2. Fetures

5. Instrument detection and maintenance
Electromagnetic flowmeter has self-diagnosis function. In addition to power supply and hardware circuit faults, the system also alarms other faults in general use. These messages give corresponding tips in the lower right corner of the screen.
1 Maintenance and repair
A) the sensor installation site shall meet the requirements of section 4, and please keep the housing clean and tidy;
B) The transmitter shall be placed in a clean, ventilated and dry place;
C) it needs to be checked every two years. for high-precision users, the instrument needs to be submitted for review.
2 transportation and storage
A) the instrument must be packed before transportation and handled with care.
B) The storage place must be dry and ventilated to avoid corrosive gas erosion, and the ambient temperature should not be too low or too high;
C) the storage time should not exceed three years.
3. Unpacking inspection
A) the package cannot be opened with a heavy hammer, so be careful not to damage the instrument.
B) carefully check the contents according to the packing list.
