Electromagnetic Flow Meter for Textile Industry / City
Administration / Water Works / Environment Protection
1. Introduction
The MLF electromagnetic flowmeter works according to Faraday's law
of electromagnetic induction and consists of a sensor and a
converter. Used to measure the conductivity of liquids or solids.
Under normal circumstances, its conductivity should be greater than
5μS/cm (the conductivity of tap water and raw water is about
100-500μS/cm), and it can also be used to measure acids, alkali,
brine, pulp or pulp and other media. But these media cannot contain
a lot of magnetic substances and bubbles.
MLF electromagnetic flowmeter is an instrument for measuring liquid
fluidity. It is widely used in flow measurement in metallurgy,
chemical industry, paper making, environmental protection,
petroleum, textile, food, urban management, water plant and other
industries.
2. Quick Details
MLF electromagnetic flowmeter is explosion-proof design.
Function of low conductivity measurement.
There are nine language options to meet the needs of different
customers.
It has the function of self-regulation and self-examination.
Different outputs are optional: Hart,RS485 Profibus,4-20mA,
frequency, pulse.

5. Instrument Testing & Maintenance
Electromagnetic flow converter has self-diagnosis function. In
addition to the power and hardware circuit fault, The system also
give alarm to other faults in general usage. These information are
given accordingly prompts in the lower right of the screen.
1 Maintenance and repair
a) The sensor installation site should meet the requirements of
Section 4, please keep the housing tidy;
b) The transmitter should be placed in a clean, ventilated and dry
place;
c) It needs to be inspected every two years. For high-precision
users, the instrument needs to be submitted for review.
2 Transportation and storage
a) The instrument must be packaged before transportation, and be
handled with care when loading and unloading.
b) The storage place must be dry and ventilated to avoid corrosive
gases, 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, be careful not
to damage the instrument
b) Check the contents carefully according to the packing list.
