advantage The measurement channel of the electromagnetic flowmeter is a smooth straight pipe with no obstructive flow detection element. It is not easy to block because it is suitable for measuring liquid-solid two-phase fluids containing solid particles such as pulp, coal water slurry, pulp, mud, and sewage. Shortcomings Electromagnetic flowmeters cannot measure liquids with very low electrical conductivity, such as petroleum products and organic solvents. Electromagnetic flowmeters cannot measure gases, steam, and liquids that contain large bubbles. General-purpose electromagnetic flowmeters cannot be used for higher temperature liquids because of the restrictions of lining materials and electrical insulating materials; some types of instruments are used for liquids below the room temperature, and damage the insulation due to condensation (or frost) on the outside of the measuring tube http: //.

The electromagnetic flowmeter does not generate pressure loss due to the detection of flow. The resistance of the instrument is only the resistance along the same length of the pipeline, and the energy saving effect is significant. It is most suitable for large-diameter water supply pipelines requiring low resistance loss.
The volumetric flow rate measured by the electromagnetic flowmeter is virtually unaffected by the slow changes in fluid density, viscosity, temperature, pressure, and conductivity.
Compared with most other flow meters, electromagnetic flowmeters require lower straight pipe sections.
Electromagnetic flowmeters have a large measuring range, usually 20:1 ~ 50: l, with a wide range of optional flow rates. The full-scale liquid flow rate can be selected within 0.5 to 10 m/s. Some models can expand and reduce the flow in the field as needed (for example, with a 4-digit potentiometer to set the meter constant) and do not have to be taken off-line for real-time flow calibration.
The range of the electromagnetic flowmeter is wider than other types of flowmeters, from a few millimeters to 3 meters.
Measurable positive and negative two-way flow, can also measure pulsating flow, as long as the pulsation frequency is much lower than the excitation frequency.
Instrument output is essentially linear.
The variety of materials that are easy to select with the fluid contact can be applied to corrosive fluids.
