Application characteristics of precession vortex flowmeter in gas flowmeter
At present, there are many kinds of gas flow meters, and today, the flow meter manufacturer Aister meter mainly talks about some of the characteristics of a cost-effective flow meter in the gas flow meter – precession vortex flow meter.
1, the type of instrument has been selected (for example, in the case of precession vortex flowmeters, followed by the selection of instrument specifications and supporting components is crucial. Therefore, two basic principles should be grasped in the selection process; That is, one must ensure the accuracy of use, and the other must ensure the safety of production. To do this, it is necessary to implement the selection parameters, the minimum and commonly used instantaneous flow rate (mainly for the size of the selected instrument) the design pressure of the measured medium (mainly for the nominal pressure level of the selected instrument) the working pressure (mainly for the pressure level of the selected instrument pressure sensor)
2, followed by automatic compensation and compression factor automatic correction. It can also directly detect the normal volume of gas or the mass flow of saturated steam. Using advanced microcomputer technology and high-performance integrated chip, the precession vortex gas flowmeter can detect the temperature and pressure of the medium. Using advanced micro power consumption technology, low power consumption of the whole machine. The flowmeter can be operated by internal battery and external power supply.
3, because the precession vortex flowmeter is a speed flowmeter, the fluid through the throttle break to accelerate the vortex flow, pressure loss will occur, therefore, the use should prevent the following problems:
1) The measuring medium is well guaranteed to be a single Newton body, if there are more impurities in crude oil and trace particles, it should be separated and filtered before the flow meter, otherwise it will cause the measurement value to be greater than the actual value.
2) The selection of the flowmeter should be based on the actual flow of the medium, rather than the diameter of the installation pipeline, which is very important.
3) To prevent the measurement error due to the range selection of the pressure sensor and the error change of the temperature and pressure sensor. At the same time, because the precession vortex flow meter used in the oilfield is mostly used for non-trade measurement handover, the flow meter fails to be verified on time, resulting in the zero drift of the pressure and temperature sensor, resulting in the increase of the error of the natural gas. Therefore, it is necessary to check the flow meter on schedule.
