Precession swirl vortex flowmeter For the majority of users who use the precession vortex flowmeter for the first time, I believe that you will encounter more or less problems when using the product. In order to better use the product, we will give you a brief introduction to the precession. Vortex flowmeter needs attention:
1, first of all, we must pay attention to the instrument selection (for example, in the case of precession vortex flowmeter, followed by the choice of instrument specifications and supporting components is essential. To this end, the selection process should grasp two basic principles; That is, one must ensure the accuracy of use, and the other must ensure production safety.To achieve this, it is necessary to implement three selection parameters, ie, the maximum, minimum, and commonly used instantaneous flow rates in the short-term and long-term (mainly used for selected instruments. Size and size) The design pressure of the measured medium (mainly used for the nominal pressure rating of the selected instrument) Working pressure (mainly used for the pressure rating of the selected instrument pressure sensor)
2, with the automatic compensation and compression factor automatically corrected. It is also possible to directly measure the normative volume of gas or the mass flow of saturated steam.
3, because the precession vortex flowmeter is a speed-type flowmeter, the fluid through the throttling of the vortex flow acceleration, pressure loss will occur.
The use of precession vortex flowmeters should prevent the presentation of problems:
1) The well-measured medium is guaranteed to be a single Newtonian body. If there are many impurities in crude oil and trace particles, they should be separated and filtered before the flowmeter. Otherwise, the measured value will be larger than the actual value.
2) The selection of the flow meter should be based on the actual flow of the medium, not the diameter of the installed pipeline, which is very important.
3) It is necessary to prevent measurement errors due to the pressure sensor's range selection, temperature, and pressure sensor error variation. Since the pressure sensor range of the currently used smart precession vortex flowmeter is 2.0Mpa gas actual range pressure ≤ ± 0.3Mpa, This will increase the measurement error of natural gas under normal conditions. At the same time, since most of the precession vortex flowmeters used in oil fields are used for non-trade custody transfer, the flowmeters fail to be verified on schedule, resulting in the zero drift of pressure and temperature sensors, which can cause natural gas transmission to increase in error. Therefore, it is necessary to flowmeters. On schedule, proofreading is proofread.
