More flow meter manufacturers choose model price quote you are welcome to inquire, here are the five main factors led directly to the electromagnetic flow meter scale measurement error of the article details.
Electromagnetic flowmeter is through the research and development of ferrari's principle of electromagnetic induction, so its advantage would be effective inheritance, but the downside is that will be affected by electromagnetic interference of the outside world, if there is no effective treatment when installation these external factors are easy to make the electromagnetic flow meter in the measurement error.
Below we will summarize the five main factors affecting electromagnetic flowmeter appear error 1, the measurement of liquid in the pipeline for full package appear this phenomenon is mainly due to the lack of back pressure in the piping or the flow sensor pipe under state caused by bad installation, the corresponding fault also should have different performance under the degree of tube (1), when a small amount of gas in a stratified flow in pipe or wavy flow distribution, the measurement results will appear inconsistent with is the result;
(2), when the fluid is living or plug flow, bubble flow, except do not tally with the actual measurement results will also because when bubbles through the instrument sensor instantaneous covered electrode surface, that cause the instrument's measurement data fluctuation;
(3), when the pipe fluid circulation sectional area increase, said fluid pipe under state also increases, also can appear instrument measurement data fluctuation;
(4), under state of pipe when the pipe is serious, serious to the liquid level under the electrode of flowmeter, the instrument will appear super full phenomenon, this kind of failure is mainly due to the user when the selection of its own flow range estimates are not allowed to cause;
2, measuring the liquid containing solid when measuring liquid powder, granule or other fiber is contained in solid general performance fault as follows (1), such as pipe flowmeter appear noise;
(2), the electrode surface;
(3), sediments or sedimentary cover of the insulation of the pipe inner conductive electrode performance or lining;
(4), meter liner wear and tear, or appear sediments leads to fluid circulation sectional area increase/decrease;
3, easy to be crystallized liquid some easy crystallization in at normal temperature, is the use of the electromagnetic flowmeter measurement, but the premise is pipe has good thermal resistance, but mostly is electromagnetic flowmeter sensor measuring tube is difficult to maintain a constant temperature, once due to lower temperature.
Liquid will be covered in case of crystallization in the surface of the pipe, instrument faults four grounding, electromagnetic flow meter part of material selection no cause for such failure, the electromagnetic flowmeter points during the production of our factory has been integrated in the instrument grounding loop, the users don't need to worry about after purchase of this kind of problem, as long as the instrument of the grounding line 5, the electrical conductivity of liquid is not up to par with the working principle of electromagnetic flowmeter ferrari's principle of electromagnetic induction, so in the measurement of liquid in the liquid conductivity must have certain requirements & ge;
5μ
S/cm, when the conductivity of the fluid is smaller than the limit but also can make the instrument measurement data fluctuate summary: from the above these faults can be concluded that most of the fault is in can effectively solve the selection and installation phase, so the user after the purchase of instrument, suggest try to extract some time to read the related installation operation, to avoid the incorrect malfunction should be installed, and can seriously damage the instrument.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
