Aister shares common fault analysis of precession vortex flowmeters
2021-06-29
The precession vortex flowmeter is a kind of rate instrument, which can be used to measure the flow of a variety of substances such as crude oil, steam, gas, etc., and complete the automatic compensation of the dynamic main parameters such as working pressure, temperature and compression coefficient on the line, which can not only display a variety of main parameters on the spot, but also a variety of data signals can be transmitted far. Widely used in crude oil, chemical plants, metallurgical industry, pharmaceutical industry and its city gas radiation heating pipeline network of a variety of vapor body measurement and flow monitoring. In oil and gas fields, it is used for gas measurement and verification of associated gas in oil and gas Wells, air intake in cooperative stations, and external gas collection stations.
1.the precession vortex flowmeter installation does not meet the requirements
The precision-vortex flowmeter is a liquid oscillation instrument panel, which has higher requirements on the spot, and the instrument mainly shows the common phenomenon when installing on the spot, the distance between the front and back pipes is relatively close, and the center line of the shell is different from the center line of the pipeline, which will lead to the data error of the instrument panel;
2.the total gas flow is not stable
The gas supply changes with time and is a pulsating beverage liquid. The working pressure caused by arbitrary pulsation in the accurate measurement may cause arbitrary impact on the whirlpool, which will harm the measurement accuracy.
3.the precession vortex flowmeter is a liquid oscillation instrument panel, in the pipeline vibration, the piezoelectric sensor can detect the change caused by the vibration, so there will be data signal output;
4.the precession vortex flow meter provides for material cleaning, because the gas contains a lot of saturated water steam, ice solidification when the temperature is reduced, metering and verification separation equipment often appears gas supply oil situation, resulting in water in the pipeline, a single well associated gas separation is not clean or with dirty oil and sand and other residue, The data error of the instrument panel is caused by the sand abrading the vortex generating body and the residue such as dirty oil sticking to the surface of the vortex generating body.
If you have other difficult problems to solve, you must consult, you can contact Aister meter staff anytime, anywhere, we can provide you with solutions.
