How to improve the measurement precision of the electromagnetic flowmeter
by variable diameter we all know that electromagnetic flowmeter measurement principle is Faraday's law of electromagnetic induction, it is mainly used to measure volume flow of conducting liquid and slurry in the closed pipeline.
After many years of practical operation.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to improve the measuring accuracy of electromagnetic flow meter scale by reducing the article details.
How to improve the measurement precision of the electromagnetic flowmeter by variable diameter we all know that electromagnetic flowmeter measurement principle is Faraday's law of electromagnetic induction, it is mainly used to measure volume flow of conducting liquid and slurry in the closed pipeline.
After many years of practical operation and observation comparative analysis, we believe that in the field of water metering, electromagnetic flowmeter is superior to other measuring instrument.
In practice, often appear due to user nature of water tube flow velocity is low, and can't meet the requirements of electromagnetic flowmeter for velocity range, so this time need to variable diameter pipe processing.
Particular way is, pipes, pipe fittings and valve diameter according to the system integration after using the parameters is selected, select the sensor diameter is smaller than measure the diameter size of electromagnetic flowmeter, that is to say, the table of the measured pipe diameter electromagnetic flowmeter with diameter is not consistent, pipe diameter, table size small, reducer added before and after installing a connection sensors.
As a result the installation local pipeline improves the velocity of electromagnetic flowmeter, meet the requirements of the flowmeter for velocity range.
In variable diameter processing work, must pay attention to the reducer need to meet the requirement of taper.
Electromagnetic flowmeter of inlet and outlet of straight section length requirement, reducer, added before and after the sensor to be seen as part of a straight pipe, should be consistent with the product on the sensor before and after the section of divergent or convergent cone Angle is less than 15 & deg;
When the reducer can't satisfy the requirement of taper, must be custom-made extended divergent or reducing pipe.
Electromagnetic flow meter is used for measurement of water supply, due to its sensors have velocity requirements, but the velocity and the characteristics of wide range, designers can according to user's water consumption and the scene actual situation, make some flexible changes, it saves water meter set of investment, and the flowmeter can run in good working condition.
Electromagnetic flowmeter, by the way, the upstream side should be not less than 5 d pipe diameters of straight pipe, the downstream side should be not less than three times the pipe diameter of straight pipe.
If there are not fully open the gate or valve upstream, the length of the straight pipe upstream of the flowmeter should be increased to 10 times the pipe diameter.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
