If the medium contains solid particles, the flow rate should be less than usual 3m / s, to prevent excessive friction lining and electrode; for viscous fluid, the flow rate can select more than 2m / s, the larger the flow rate on the electrode attachment helps to automatically eliminate the sticky Lag substrates, help improve the measurement accuracy. Q has been determined in the range of conditions, to determine the size of the meter diameter D of the velocity V of the above range, the value is calculated by the following formula: Q = πD2V / 4 Q: flow rate (m / h) D: pipe diameter V : flow rate (m / h) Range Q electromagnetic flowmeter flow should be greater than the maximum expected value, and the normal flow value slightly larger than the 50% full scale of the meter is appropriate.

So it will not cause any additional pressure loss when the fluid passes through the meter, is one of the lowest energy consumption flow meter flowmeter. 2) Dirty measurable medium, corrosive media and suspension of liquid-solid two-phase flow. This is because the instrument in the measuring pipe unimpeded flow of parts, in contact with the fluid to be measured is measured pipe-lining and the electrode, and its material may be selected according to the nature of the measured fluid. For example, do polytrifluoroethylene or Teflon-lined, measure a variety of acid, alkali, salt and other corrosive media; do wear-resistant rubber lining, it is particularly suitable for measuring with solid particles, wear larger pulp, cement mortar phase fluids with fiber and a variety of liquid and pulp suspension body. 3) electromagnetic flowmeter is a volumetric flow measurement instruments, in the measurement process, it is not measured medium temperature, viscosity, density conductivity (in a certain range) effects. Therefore, the electromagnetic flowmeter calibrated simply with the water, the heart can be used to measure the flow rate of other conductive liquid. 4) output electromagnetic flowmeter and the average velocity is proportional to the measured only medium with the flow state under symmetric distribution (laminar or turbulent) irrelevant. So span a very wide range of the electromagnetic flowmeter, the measurement range of up to 100: 1, and some even up to 1000: 1 flow range can run. 5) electromagnetic flowmeter no mechanical inertia, responsive, you can measure the instantaneous flow pulsation, but also measure the flow of both positive and negative directions. 6) Industrial caliber electromagnetic flowmeter very wide range, from a few millimeters up to several meters, and the country has a diameter up to 3m of actual flow calibration equipment, laid the foundation for the application and development of electromagnetic flowmeter. The main deficiency of ethanol flowmeters that are still present are: a) can not be used to measure gases, vapors and liquids containing a large amount of gas. b) can not be used to measure the conductivity of low liquid medium, such as petroleum products or organic solvents, and other media, the current electromagnetic flowmeter powerless. c) Due to general industrial use electromagnetic flowmeter measuring tube lining material and limitations of electrical insulating materials, can not be used to measure the temperature medium; without the special treatment, it can not be used to measure temperature medium to prevent condensation measuring tube (frost) damage to the insulation. d) electromagnetic flowmeter susceptible to external electromagnetic interference.
