Brief Introduction of Integrated Electromagnetic Flowmeter Products;




Intelligent electromagnetic flowmeter is an electromagnetic induction type flow meter with nominal diameter ranging from 10 to 3000. It is a series of electromagnetic flowmeter products integrating intelligence, small size, light weight, multifunction, high precision and high reliability.  It consists of sensor and intelligent converter.


The intelligent electromagnetic flowmeter is suitable for measuring liquid-solid two-phase fluid containing solid particles or fibers due to its smooth straight pipe with a measurement channel that is an open flow detection piece and is not easy to block.  At the same time, the electromagnetic flowmeter does not generate pressure loss caused by flow detection, and the resistance of the meter is only the resistance along the pipeline of the same length, so that the energy-saving effect is remarkable, and the electromagnetic flowmeter is most suitable for large-diameter water supply pipelines requiring low resistance loss;  The volume flow measured by electromagnetic flowmeter is not affected obviously by the changes of fluid density, viscosity, temperature, pressure and conductivity (as long as it is above a certain threshold value).  Compared with most other flow meters, the front straight pipe section requires less.  Electromagnetic flowmeter has a large measuring range, usually 20: 1 ~ 50: 1, with a wide optional flow range.  Its caliber range is wider than that of other types of flow meters, ranging from a few millimeters to 3 meters.  It can measure both positive and negative bidirectional flow rate and pulsating flow rate as long as the pulsating frequency is much lower than the excitation frequency.  The instrument output is linear in nature;  It is easy to select the material variety of the contact piece with the fluid, and can be applied to corrosive fluids and other advantages.
