Magnetic Flow Meter: How It Works
The sanitary electromagnetic flowmeter is a flow measurement instrument specifically designed for industries with high hygiene requirements, such as food, pharmaceuticals, and beverages. It operates based on Faraday’s law of electromagnetic induction, calculating the flow rate by utilizing the electromotive force (EMF) generated when a conductive medium cuts magnetic field lines.
According to Faraday’s principle of electromagnetic induction, a pair of detection electrodes are installed on the pipe wall perpendicular to the axis of the measuring pipe and the magnetic field lines. When the conductive liquid moves along the axis of the measuring pipe, it cuts the magnetic field lines, generating an induced EMF. This induced EMF is detected by the two electrodes, and its value is directly proportional to the flow velocity. Its value is:
Where: E = B.V.D.K
E – Induced EMF;
K – Coefficient related to magnetic field distribution and axial length;
B – Magnetic induction intensity;
V – Average flow velocity of the conductive liquid;
D – Electrode spacing (inner diameter of the measuring pipe)
The sensor transmits the induced EMF E as a flow signal to the converter. After amplification, conversion, filtering, and other signal processing, the instantaneous flow rate and cumulative flow rate are displayed on a backlit dot-matrix LCD. The converter has 4-20mA output, alarm output and frequency output, and is equipped with RS-485 and other communication interfaces, and supports HART and MODBUS protocols.
A minimum straight pipe section of 5D length is required before the flow meter and a minimum straight pipe section of 3D length is required after it, where D is the inner diameter of the flow meter. For ease of installation and disassembly, a pipe expansion joint can be installed after the flow meter.
When an electromagnetic flow meter is operating, the liquid’s conductivity should be higher than 5 μS/cm. Below this value, the induced electromotive force is too small, the signal-to-noise ratio decreases, and this may lead to measurement instability or increased error.
For some high-performance electromagnetic flow meters, the conductivity can be reduced to 1 μS/cm or lower, but the specific value depends on the flow meter’s design and the manufacturer’s specifications.
Common conductive liquids (such as water, brine, and acid/alkali solutions) generally meet the conductivity requirements. Pure water or deionized water has lower conductivity (0.055~10 S/cm) and may require a high-sensitivity electromagnetic flow meter.
If the liquid’s inherent conductivity is insufficient, an appropriate amount of conductive agent (such as salt or acid/alkali solution) can be added to improve it, but care must be taken to ensure this does not affect process requirements.
For low-conductivity or non-conductive liquids, other types of flow meters can be selected, such as ultrasonic flow meters or mass flow meters.
Electromagnetic flow meters are a common type of flow meter, but they have limitations in certain situations. For example, they cannot be used with non-conductive liquids, in high-temperature and high-pressure environments, in liquids containing air bubbles or particles, or in high-viscosity liquids.
Furthermore, liquids with a volumetric gas content exceeding 5% and liquids with magnetic properties are also unsuitable for measurement using electromagnetic flow meters. In specific situations, it is necessary to select a suitable flow meter and take appropriate measures to ensure measurement accuracy and reliability.
Electromagnetic flow meters are typically classified into several accuracy levels, including:
0.2 level: Measurement error within ±0.2%, suitable for applications requiring extremely high accuracy.
0.5 level: Measurement error ±0.5%, suitable for high-precision applications in industries such as chemical and pharmaceutical manufacturing.
1.0 level: Measurement error ±1%, suitable for general industrial applications, meeting most routine flow monitoring needs.
Yes, you can calibrate an electromagnetic flow meter yourself. Calibration of an electromagnetic flow meter requires following certain standards and procedures to ensure the reliability and accuracy of the measurement results.
On-site calibration of an electromagnetic flow meter should be performed according to the following steps:
Verify that the calibration environment meets requirements, including temperature, pressure, and medium conditions.
Inspect all equipment connections before calibration to ensure they are secure and leak-free.
Select appropriate calibration equipment and tools, such as flow calibrators and standard flow meters.
Gradually adjust the flow rate according to the specified procedure, recording the flow meter’s indicated values.
Calculate the flow meter’s error and perform necessary adjustments.
After calibration, organize data, perform error analysis, and prepare the calibration report.
