Differential pressure flow meter scale signal distortion

Abstract: the reasons of the distortion of differential pressure flowmeter scale signal information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In the installation of differential pressure flowmeter standard specification, the lead of laying pipe installation and instrumentation generally simply referred to by the way, that there should be no transmission distortion of the differential pressure signal. In fact to really do not distortion of differential pressure signal transmission is very not easy. There is. More flow meter manufacturers choose model price quote you are welcome to inquire, differential pressure flowmeter is below the article details the cause of scale signal distortion. In the installation of differential pressure flowmeter standard specification, the lead of laying pipe installation and instrumentation generally simply referred to by the way, that there should be no transmission distortion of the differential pressure signal. In fact to really do not distortion of differential pressure signal transmission is very not easy. Has been: just parking in differential pressure type flowmeter, or conditional will be equipped with a differential pressure type flowmeter device on the pipeline of the valve is closed, and confirmed through the flowmeter flow rate has dropped to zero, from the point of specific flow meter readings, really zero value is not much. Zero drift of the most main reason for the distortion in the process of differential pressure transmission. The differential signal transmission distortion makes the differential pressure transmitter receives pour on differential pressure signal and differential pressure signal generated by the differential pressure type flowmeter is not equal, causing additional error. The differential signal distortion including steady-state value distortion and dynamic distortion. Under the condition of steady flow distortion exists only steady-state value, under the condition of the pulsating flow, there may be a steady-state value distortion and there will be a dynamic distortion. The region and the reasons of steady-state value distortion may cause: to guide the pressure pipe is not reasonable; Cut-off valve Settings; Condenser height unequal; Spacer liquid level height is not equal; Slope led pressure tubes was unreasonable; Tube medium density not equal; Three valve group effusion, etc. ( 1) Guide tube to unreasonable and set the error due to improper cut-off valve, zui easy to cause the differential pressure type steam flowmeter, shall be installed in accordance with the standard specification for installation. Velocity-equalizing tube differential pressure flow meter used to measure the possible precipitation of condensate of low pressure gas flow, the level set of needle type cut-off valve may lead to blockages in condensate to accumulate in the valve of gas circuit to produce differential pressure signal distortion. ( 2) Condenser height error caused by unequal, are two negative pressure pipe condenser should be symmetrical structure, installation height should be equal, which can potentially make two condenser in liquid level height are equal, because the level of a difference of 1 mm will be the introduction of 10 pa differential pressure distortion. But in the use of the site not only two condenser installation height of unequal situation often see it, and some even condenser inversion, didn't have the effect of condenser. Plus or minus of elbow flowmeter with an open mouth in the bend in the outer ring, another open in bend pipe inner circle, in a larger diameter, it is easy to cause highly unequal, due to the differential pressure signal of elbow flowmeter is original is very small, so the differential signal distortion from absolute numerical differential pressure is not too big, but the relative error caused by the flow measurement is considerable. ( 3) Spacer liquid level height error caused by unequal, pressure in the pipeline with isolator is to take advantage of spacer with differential pressure transmitter will be corrosive medium in isolation. Spacer just filling, through three valve group balancing valve can make the two isolated container liquid level height consistent. But run after a period of time due to the isolation liquid leakage or driving balance valve at run time, may lead to isolation fluid level height are not equal, to introduce additional differential pressure caused by the differential signal distortion. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
