The concept of an Electromagnetic Flowmeter (EMF) has been around for decades. Its early applications were used to measure blood flow rates. Now, this technology is being used to measure flow rates of many liquids, including air, liquids in tanks, and liquids in piping systems. Here are some of the benefits of EMF flowmeters.
Electrically insulating metering tubes, typically stainless steel, are used in electrolyte flowmeters. The choice of liner material depends on the type of liquid and the type of the electrolyte. Electrolytes range from slurries to molasses to chemically aggressive mixtures to molten metal. The electrolyte's conductivity threshold can be as low as five micro-Siemens/cm, although some manufacturers claim to be even lower. Electrolytes are affected by the flow of the fluid and the density of the fluid.
Electromagnetic Flowmeters can detect the flow of a variety of liquids, including thick fluids, viscous fluids, and multiphase liquids. They are also excellent at measuring the flow rate of abrasive or dirty fluids. Magnetic flowmeters are easy to install and maintain and are also compatible with many pipe sizes. These versatile devices are perfect for a wide variety of applications, including pulp, food, and grout.
The primary difference between these meters and other magnetic flowmeters is the lack of complexity. Unlike their magnetic counterparts, magnetic flow meters are made up of only two basic components: the transmitter and sensor. This ensures that magnetic measurements are precise to the millimeters' accuracy. They can measure liquid flows in either direction, although reversing the direction changes the polarity of the signal. In this case, however, the magnetic intensity of the flow signal falls to zero.
