If the medium contains solid particles, the flow rate should be less than conventional 3m / s, to prevent excessive friction lining and the electrodes; for viscous fluids, optionally greater than the flow rate of 2m / s, the larger the flow rate on the electrode attachment helps automatic elimination of stick hysteresis effects thereof, will 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 : velocity (m / h) Range Q electromagnetic flowmeter should be greater than the expected maximum flow value, whereas the normal flow values ??are slightly larger than the 50% of full scale flow 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 liquid medium and the suspension of the solid flow of traffic. This is because the instrument measuring the inside of the tube member without obstructing the flow in contact with the fluid to be measured is the lining of the measuring tube and the electrode, the material may be selected according to the nature of the fluid to be measured. For example, polytrifluoroethylene or PTFE lined, measure a variety of acids, bases, salts and other corrosive media; wear-resistant rubber lined, it is particularly suitable for the measurement of solid particles with wear large pulp, grout and other phase fluids and a variety of liquid and pulp with a fiber suspension body. 3) The electromagnetic flowmeter is a volumetric flow measurement instruments in the measurement process, it is not the temperature of the measured medium, viscosity, density electrical conductivity (in a certain range) effects. Therefore, the electromagnetic flowmeter of water just after the calibration, the heart can be used to measure the flow rate of other conductive liquid. 4) The output of electromagnetic flowmeter and the average velocity is proportional only measured media, but with symmetrical distribution under flow conditions (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 be run. 5) The electromagnetic flowmeter no mechanical inertia, responsive, can measure the instantaneous pulsating flow, but also measure the flow of both positive and negative directions. 6) Industrial diameter range of the electromagnetic flowmeter is extremely wide, 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 use and development of electromagnetic flowmeters. Electromagnetic flowmeters are still major problems exist as follows: a) can not be used to measure the gas, vapor and a liquid containing a large amount of gas. b) can not be used to measure very low conductivity liquid medium, such as petroleum products or organic solvents and other media, the current electromagnetic flowmeters still powerless. c) general industrial use electromagnetic flowmeter measuring tube lining material and due to limitations of electrical insulating materials, and can not be used to measure temperature medium; as without special treatment, can not be used to measure the cryogenic medium to prevent the measuring tube condensation (frost) damage to the insulation. d) Electromagnetic Flowmeter susceptible to external electromagnetic interference.
