IP65 IP67 IP68 Battery Operated Electromagnetic Flow Meter Explosion Proof Long Life Time
1. Introduction
The MLF electromagnetic flow meter 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. In general, its conductivity should be greater than 5μs/cm (tap water, raw water conductivity of about 100 to 500μs/cm), can also be used to measure acids, alkali, brine, pulp or pulp and other media. However, these media must not contain large amounts of magnetic substances and bubbles.
MLF electromagnetic flow meter is an instrument for measuring liquid flow. Widely used in metallurgy, chemical, paper, environmental protection, petroleum, textiles, food, urban management, water plants and other industries flow metering.

1 Maintenance and repair.
A) the sensor installation site should meet the requirements of Section 4, please keep the shell clean and tidy.
B) the transmitter should be placed in a clean, ventilated and dry place.
C) it needs to be checked every two years, and for high-precision users, the instrument needs to be submitted for review.
2 Transportation and storage.
A) the equipment must be packed before transportation and handled carefully during loading and unloading.
B) the storage place must be dry and ventilated to avoid the erosion of corrosive gases and the ambient temperature should not be too low or too high.
C) the storage time should not exceed three years.
3. Out-of-the-box inspection.
