2 Inch Flowmeter Water Magnetic Electromagnetic Flow Meter For Acid
Alkali
Electromagnetic flowmeters (EMF) have been used for continuous flow
measurement in industrial applications for many years. They are
ideally suitable for liquids with an electrical conductivity
greater than 5 μS/cm. In addition to water and waste water, other
contaminated liquids are typical areas of application.
The underlying measuring principle of the EMFs is based on
Faraday's law of induction. The coils of the flowmeter generate a
magnetic field orthogonal to the flow direction. According to
Faraday's law of induction, a conductive liquid passing through the
magnetic field induces a current between the two electrodes, which
can be used to measure the voltage. The higher the flow velocity,
the higher the induced voltage. This voltage signal is converted
into a standard signal (e.g. 4 - 20 mA or P) by the integrated
electronics.
Electromagnetic Flow Meters, simply known as mag flow meter is a
volumetric flow meter which is ideally used for waste water
applications and other applications that experience low pressure
drop and with appropriate liquid conductivity required.
The device doesn’t have any moving parts and cannot work with
hydrocarbons and distilled water. Mag flow meters are also easy to
maintain.
Features
1. There are no flowing and blocked flow parts in the pipeline of
the 50mm water oil electromagnetic flow meter, and there is almost
no additional pressure loss in the measurement.
2. The measurement result of the 50mm water oil electromagnetic
flow meter has nothing to do with physical parameters, such as flow
distribution, fluid pressure, temperature, density and viscosity.
3. The electromagnetic flowmeter uses a fast, high-precision 16-bit
embedded processor to enhance the measurement stability.
4. The 50mm water oil electromagnetic flow meter has
anti-interference and high reliability, and the measurement range
is up to 150: 1.
5. The flowmeter adopts ultra-low EMI switch, and the power supply
voltage range is wide.
