The measurement channel of an electromagnetic flowmeter is a smooth straight pipe without any flow-obstructing elements; since it is not prone to blockage, it is suitable for measuring two-phase fluid mixtures containing solid particles or fibers, such as pulp, coal water slurry, mineral slurry, mud, and sewage. Electromagnetic flowmeters do not generate pressure losses resulting from the measurement of flow rate; the resistance of such instruments corresponds to the frictional loss in a pipe of the same length. They offer significant energy savings, making them ideal for water supply pipelines where low resistance losses are required. The volumetric flow rate measured by an electromagnetic flowmeter is, in fact, not significantly affected by changes in fluid density, viscosity, temperature, pressure, and conductivity (as long as they remain above a certain threshold). Compared to most other flow meters, the requirement for a straight pipe section ahead is lower. Electromagnetic flowmeters cannot measure liquids with very low conductivity, such as petroleum products and organic solvents, nor can they measure gases, vapors, or liquids containing many large bubbles. Due to the limitations of the lining material and electrical insulation material, general-purpose electromagnetic flowmeters cannot be used with liquids at high temperatures ； Some models of instruments are used for liquids below room temperature, and the insulation is damaged due to condensation (or frost) on the outside of the measuring tube. Solids-containing fluids such as drilling mud, drilling cement slurry, and pulp are actually non-Newtonian fluids. Since the solids flow together with the carrier fluid, there is sliding between them and a difference in speeds; therefore, instruments calibrated for single-phase fluids will introduce additional errors when used with solid-liquid two-phase flows. There is a limit to the lower threshold for flow rate measurement, and the operating pressure is restricted. In practical applications, large-diameter electromagnetic flowmeters are commonly used in water supply and drainage projects. Small-diameter pipes are commonly used for measuring difficult-to-measure fluids such as those with identical densities, as well as in applications with high requirements; for example, in measuring pulp and black liquor in the papermaking industry, slurry in the non-ferrous metallurgy industry, coal slurry in coal processing plants, highly corrosive liquids in the chemical industry. They are also used for controlling and monitoring leaks in the cooling water systems of blast furnaces in the steel industry, as well as for measuring and controlling the flow rate of coal transported over long distances through pipelines. Small-diameter and ultra-small-diameter systems are commonly used in industries such as the pharmaceutical industry, food industry, and bioengineering, where hygiene standards are important.
