The Water Flow Meter 4 20ma Output is a kind of flow meter for sewage water, belonging to the magnetic inductive flow meter. The electromagnetic flowmeter has no moving parts and no flow blocking parts, which will not cause pressure loss, and will not cause problems such as wear and blockage. The flow meter for sewage water is a volume flow measuring instrument, which is not affected by the temperature, viscosity, density, and conductivity (within a certain range) of the measured medium during the measurement process. The electromagnetic flowmeter has a wide range, up to 1:100. In addition, the electromagnetic flowmeter is only proportional to the average flow velocity of the measured medium, and has nothing to do with the axisymmetric flow state (laminar flow or turbulent flow). The electromagnetic flowmeter has no mechanical inertia, sensitive response, can measure instantaneous pulsating flow, and has good linearity, so the measurement signal can be directly converted into a standard signal output by a converter. The LD-T type can indicate on the spot, and the LD type can transmit over a long distance.
Electromagnetic flowmeters are divided into display methods: separate electromagnetic flowmeters and integrated electromagnetic flowmeters. Series nominal diameter DN10 ~ DN2000, such as DN50 flow meter.
A split type electromagnetic flowmeter is an inductive instrument that measures the volume flow of a conductive medium in the pipe according to Faraday's law of electromagnetic induction. It adopts single-chip embedded technology to realize digital excitation. At the same time, the CAN field bus is used on the electromagnetic flowmeter, which is the first in China. The technology has reached the domestic leading level. Split type electromagnetic flowmeter can output 4~20mA current signal for recording, adjustment, and control while satisfying on-site display. It has been widely used in the chemical industry, environmental protection, metallurgy, medicine, papermaking, water supply and drainage, and other industrial technologies and management department. In addition to measuring the flow of general conductive liquids, the split electromagnetic flowmeter can also measure the volume flow of liquid-solid two-phase flow, high-viscosity liquid flow, salt, strong acid, and strong alkali liquid.
The integrated electromagnetic flowmeter is formulated according to Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive fluids. Due to its unique characteristics, it has been widely used in the measurement of various conductive liquids in industry. It is mainly used in the chemical industry, papermaking, food, textile, metallurgy, environmental protection, water supply and drainage, and other industries. It can realize system control by matching with the computer.

Water Flow Meter 4 20ma Output Working Principle
The working principle of the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductor moves in a magnetic field, an induced electromotive force will be generated at both ends of the conductor perpendicular to the direction of the magnetic field and the direction of motion. The magnitude of the electromotive force is proportional to the speed of the conductor and the magnetic induction of the magnetic field.
How to choose the electromagnetic flowmeter correctly?
What kind of electromagnetic flowmeter to choose should be determined according to the physical and chemical properties of the measured fluid medium. From the working principle of the electromagnetic flowmeter, it can be seen that the fluid that can be used to measure the flow of the electromagnetic flowmeter must be conductive. Strictly speaking, except for high-temperature fluids, any fluid with a conductivity greater than 20us/cm can use the corresponding electromagnetic flow rate. The flow meter is used to measure the flow rate, because the non-conductive gas, steam, oil, acetone, and other substances cannot use the electromagnetic flow meter to measure the flow rate.
