Errors caused by non-axisymmetric flow

The velocity distribution of the electromagnetic flowmeter symmetrically distributes the tube axis, generating the total fluid flow of the electrodes in 1 uniform electric forces, the flowmeter's liquid flowmeter's average fluid velocity distribution of the amplitude magnetic field rate, but not the ratio. The axis of symmetry, that is, the particles of the moving object, each of the different positions of the electrode shape of the induction electromotive force depends on the electrode electrode, at the particle velocity is greater, closer, the induction electromotive force larger scale, the resulting is different, therefore, you need to ensure fluid flow of the symmetrical axis. Will cause an error, such as the distribution of non axisymmetric pipe flows. Electromagnetic flowmeter options to ensure straight tube requirements to minimize errors.

Electromagnetic flow meter and vortex flow meter What are the differences

图片
        As a professional supplier of flow meter, it is very important to use the flow meter users, talk about two kinds of widely used two flow meters. The first is the electromagnetic flow meter, the second is the vortex flow meter. This is what we often use most of the two flow meters. What is the difference between them before? I will tell you from the following points: 1. Electromagnetic flow meter and vortex flow meter principle is different.    According to the principle of flange electromagnetic induction, a pair of test electrodes are installed on the wall of the tube which is 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, the conductive liquid cuts the magnetic field lines to generate the induced potential. The sensing potential is detected by two sensing electrodes. The value is proportional to the flow rate. The value is E = B * V * D * ...

Precautions for the installation of electromagnetic flowmeter

图片
     The electromagnetic flowmeter is an instrument for measuring the volume flow of the conductive fluid through the electromotive force induced by the applied magnetic field according to "Faraday electromagnetic induction principle". It consists of two parts, the sensor and the converter. It is suitable for measuring the flow of conductive liquid and slurry in closed pipes, such as clean water, sewage, various acid and alkali salt solutions, mud, pulp, pulp and food liquids.With the development of industrial technology, the advancement of agricultural science and technology.Due to its own advantages and characteristics, the use of electromagnetic flowmeter has been increasing every year.  At the same time as the amount of use is increased, the following items must be noted in the installation of the electromagnetic flowmeter:      The electromagnetic flowmeter should be installed in the correct position.     1. Installation method (as...
