The application of electromagnetic flow meters in the water industry

The characteristics of electromagnetic flowmeters in the water industry are very significant, especially in sewage treatment and other fields. The performance is particularly outstanding. The following is a summary of the characteristics, advantages, and disadvantages of electromagnetic flowmeters.

Features:

Strong adaptability: The electromagnetic flowmeter can measure difficult-to-measure fluids such as dirty flow and corrosive flow, solving the problems of other flowmeters in sewage treatment and other fields.

Accurate measurement: The measurement channel is a smooth straight tube, which is not easily blocked and is suitable for measuring liquid-solid two-phase fluids containing solid particles, such as pulp, mud, sewage, etc.

Small pressure loss: The electromagnetic flowmeter will not produce the pressure loss caused by flow detection during measurement, which has an energy-saving effect.

Small influencing factors: The measured volume flow rate is actually not significantly affected by changes in fluid density, viscosity, temperature, pressure and conductivity.

Wide caliber range: The electromagnetic flowmeter has a wide caliber range and a large flow range.

Advantages:

High adaptability: can be applied to the measurement of corrosive fluids.

Easy maintenance: The electromagnetic flowmeter has a simple structure, easy maintenance and long service life.

Disadvantages:

Limitations: It cannot measure liquids with very low conductivity, such as petroleum products, gases, steam and liquids containing large bubbles.

Temperature limitation: cannot be used for higher temperature measurements.

Application fields:

Electromagnetic flowmeters have a wide range of applications. Large-diameter instruments are often used in water supply and drainage projects, while small and medium-diameter instruments are often used in high-demand or difficult-to-measure situations, such as blast furnace tuyeres in the steel industry. Cooling water control, measurement of pulp liquid and black liquor in the paper industry, strong corrosive liquid in the chemical industry, ore pulp in the non-ferrous metallurgical industry, etc. Small-diameter and micro-diameter electromagnetic flowmeters are often used in places with hygienic requirements such as the pharmaceutical industry, food industry, and biochemistry.
