Digital Electromagnetic Flowmeter Water Flow Meter Price
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.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.
1MLF 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.
3. Quick Details
MLF electromagnetic flowmeter is explosion-proof design.
Function of low conductivity measurement.
