What is an electromagnetic flow?

Electromagnetic flow, also known as Magmeter , is a tool that measures the flow rate of liquid - or solids suspended in a liquid - a tube. These flow meters are often used to clean waste water, food processing and medical industry. In general, they rely on the conductivity of the liquid, solution or sludge, which measures - because it passes through the magnetic field and generates an electrical signal - which can be used to measure the flow of volume.

because the substance must have electrical conductivity to be measured by an electromagnetic flow by meter. Other types include the flow of vortex and ultrasonic flow. However, the electromagnetic flow meter is often non -invasive and generally does not significantly limit the flow to measure it. These devices are also very easily designed, with almost without moving parts, so they require LE littud and often may not be replaced. He found that a substance that leads electricity and moves through the magnetic field is produced by an electrical signal. Further development led to the capacityinterpret this signal through various scientific calculations to determine the speed of flow.

There are several different configurations of electromagnetic meters. Sometimes they have electrodes that protrude into the pipeline through which they measure the measured substance. The coils on the outside of the pipe produce a magnetic field while the electrodes raise the generated electricity. Until the electrodes create a coating of the measured substance, they work well.

Another type of electromagnetic flow intestine is completely non -invasive on the tube. In this type, electrodes are only located on its outside and the coils still generate magnetic fields. One of the advantages is that the liquid it measures never teases electrodes. These flow meters can also be used on closed pipe systems , which are sometimes necessary to maintain cleanliness and hygiene.

When electromagnetic flow is used, they mustbe correctly grounded. Otherwise, it can pick up electrical interference, often referred to as noise , and the flow reading will not be accurate. This may be a special problem when the tubes are plastic because they usually produce static electricity. Various earthing configurations are used depending on the design of the flowmeter and pipeline.
