The meter scale requirement for straight pipe before and after

Abstract: the flow meter scale requirement for straight pipe before and after the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. There are many types of flowmeter, the straight pipe are required meter mainly include electromagnetic flowmeter, vortex flowmeter, pig and orifice plate, etc. , most of them are the first five to the requirement of straight pipe after 3, 5 times of the corresponding diameter and 3 times. Now most of the electromagnetic flowmeter. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a meter scale requirement for straight pipe before and after the article details. There are many types of flowmeter, the straight pipe are required meter mainly include electromagnetic flowmeter, vortex flowmeter, pig and orifice plate, etc. , most of them are the first five to the requirement of straight pipe after 3, 5 times of the corresponding diameter and 3 times. Now most of the electromagnetic flowmeter using non-uniform electromagnetic field on the fluid flow velocity distribution of axial symmetry requirement is low, so the electromagnetic flowmeter can reduce appropriately, and vortex flowmeter, pig and hole threatening the fluid velocity distribution is strict, if can't meet the requirement of the straight pipe may cause you can't measure. Project construction of vortex flowmeter was not conducted according to the design requirements, and the straight pipe asked didn't reach, water linkage test time measurement is not only the question of error, the data are not allowed to be completely, then changed after straight pipe is no problem, believe should know the importance of straight pipe. If there are conditions suggest leave it long straight section. General orifice plate for the first 5 d after 10 d, also before 24 d after 7 d, zui is a straight pipe before 30 ~ 50 d as well; Before the turbine flowmeter for 15 d after 5 d; Vortex flowmeter is before 20 d after 5 d; No special requirements in quality. But general zui is a straight pipe section, length as long as possible. Effects on measurement accuracy and error we do not have no actual empirical data, if the measurement parameters are used to process control, the process can accept range of error is allowed, if it is used for measuring, such as water, gas, oil and so on should be reached its nominal accuracy, in addition to measuring instrument will be on the acceptance of the bureau of standard measurement, substandard would not pass. Need good good flowmeter the site environment and cooperation, to make flowmeter play out proper efficacy in industrial production, if because of some restrictions on the installation results in measuring, the meter will lose its significance. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
