Manufacturer of sanitary clamp electromagnetic flowmeter
The sanitary clamp electromagnetic flowmeter is used for flow measurement based on Faraday’s law of electromagnetic induction. The advantages of electromagnetic flowmeter are minimal pressure loss and a wide range of measurable flow rates. The ratio of maximum flow rate to minimum flow rate is generally above 20:1, suitable for a wide range of industrial pipe diameters. The output signal is linear with the measured flow rate, with high accuracy, and can measure liquids with conductivity ≥ 5 μ s/cm.

Working principle of sanitary clamp electromagnetic flowmeter
According to Faraday’s principle of electromagnetic induction, a pair of detection electrodes are installed on the tube wall perpendicular to the axis of the measuring tube and the magnetic field lines. When the conductive liquid moves along the axis of the measuring tube, it cuts the magnetic field lines and generates an induced potential. This induced potential is detected by the two detection electrodes, and the value is proportional to the flow rate. Its value is:
E=KBVD
In the formula:
E – Induced potential;
K – coefficient related to magnetic field distribution and axial length;
B – Magnetic induction intensity;
V – average flow velocity of conductive liquid;
D – electrode spacing; (Measuring the inner diameter of the tube)
The sensor uses the induced potential E as a flow signal, which is transmitted to the converter. After amplification, transformation, filtering, and a series of digital processing, the instantaneous and cumulative flow rates are displayed on a backlit dot matrix LCD. The converter has 4-20mA output, alarm output and frequency output, and is equipped with communication interfaces such as RS-485, and supports HART and MODBUS protocols.
Advantages of sanitary clamp electromagnetic flowmeter products
- The use of new sanitary lining materials prevents the accumulation of residual measuring media in the measuring tube;
- The measuring tube has unobstructed moving parts, no pressure loss, and low requirements for straight pipe sections;
- The sensor adopts a new generation of specialized lining technology and uses a special mirror polished PFA lining;
- The intelligent converter can simultaneously display measurement data such as volumetric flow rate percentage, instantaneous flow rate, and cumulative flow rate;
- Adopting a quick connection solution, the electromagnetic flowmeter is easy to disassemble, maintain, and clean. The intelligent converter uses a LCD backlit LED display, which can read clearly even in strong light or at night.
