                               High Accuracy Battery Operated Electromagnetic Flow Meter To Measure Liquid

1.Working Principle

The principle of the sensor is based on Faraday’s law of electromagnetic induction.It is installed a pair of detection electrodes on the pipe wall,where the measurement pipe axis and magnetic field lines are vertical. When the conductive liquid cuts magnetic field lines and produces induced electromagnetic force.Which can be measured by the two electrodes on the meter pipe.The result can be calculated by formula: Induced electromotive force,(flow signal)E=KBDV

E——Induced electromotive force,V；

K——meter constant；

B——Magnetic flux density,T；

D——Internal diameter of measuring pipe,m；

V——Average velocity of pipe section,m/s.

MLF Series Electromagnetic Flow Meter

Assume the volume of liquid as qv(m3/s),qv=πD2V/4),so in the formula E=(4kB/πD)qv=kqv,K is meter constant,K=4kB/πD.

Actually, the electromagnetic flow meter consists of two parts, transmitter and sensor, the measuring electrodes inspect the electromotive force, and transmit to the converter, the converter provides excitation current.E is usually called a flow signal, after processing the flow signal by converter, output 4~20 mA/pulse(or frequency) signal which is proportional to the flow rate, then the flow rate recording,adjusting can be achieved.

2. Quick Details

MLF electromagnetic flowmeter is explosion-proof design.

Function of low conductivity measurement.

There are nine languages 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. Maintance

The electromagnetic flowmeter has a self-diagnostic function. In addition to power supply and hardware circuit failures, the system also alarms other failures in general use. These messages will give corresponding prompts in the lower right corner 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.
