The influence of China's electromagnetic flowmeter technology in the market position

A new type of flow measuring instrument that has developed rapidly with the development of electronic technology. An electromagnetic flowmeter is an instrument that applies the principle of electromagnetic induction to measure the flow of a conductive fluid based on the electromotive force induced by the conductive fluid through an applied magnetic field. The following small series is mainly for everyone to introduce.

1. Measurements are not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
2. There is no obstructed flow component in the measuring tube, no pressure loss, and the requirements of the straight pipe section are low. Unique adaptability to slurry measurement;
3. Reasonable selection of sensor lining and electrode materials, that is, good corrosion resistance and wear resistance;
4. The converter adopts novel excitation mode, low power consumption, stable zero point and high precision. The flow range can reach 150:1;
5. The converter can be integrated with the sensor or separated;
6. The converter adopts 16-bit high-performance microprocessor, 2x16LCD display, convenient parameter setting and reliable programming;
7. The flowmeter is a two-way measuring system with three totalizers: positive total, reverse total and total difference; can display positive and negative flow, and has multiple outputs: current, pulse, digital communication , HART;
8, the converter uses surface mount technology (SMT), with self-test and self-diagnosis function;

9. Measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. The sensor induced voltage signal has a linear relationship with the average flow velocity, so the measurement accuracy is high.

In summary, it has a series of excellent features that can solve the problems that other flowmeters are not easy to apply, such as the measurement of dirty flow and corrosion flow. Wide range of applications, large-diameter instruments are used in water supply and drainage projects; small and medium-sized calibers are often used in high-demand or difficult-to-measure applications.
