There are four reasons for the inaccurate measurement accuracy of the precession vortex gas flow meter

Abstract: The measurement accuracy of the precession vortex gas flow meter is inaccurate. There are 4 reasons for the inaccuracy of the measurement accuracy. Precession vortex gas flowmeter is a fluid oscillating flowmeter developed and put into the market in recent decades, which can be used for flow measurement of various media such as oil, steam, natural gas, and water. It has a compact structure, intuitive and clear reading, high reliability and no resistance. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the inaccurate measurement accuracy of the precession vortex gas flowmeter. There are four reasons for the article details. Precession vortex gas flowmeter is a fluid oscillating flowmeter developed and put into the market in recent decades, which can be used for flow measurement of various media such as oil, steam, natural gas, and water. It has obvious advantages such as compact structure, intuitive and clear reading, high reliability, no interference from external power supply, lightning resistance, low cost, etc. quantity. In the actual use process, the measurement accuracy of the precession vortex gas flowmeter is often inaccurate due to various reasons. These reasons generally include the following aspects: 1. The working environment is relatively harsh, such as electromagnetic field interference, dust, high temperature, Vibration, humidity, etc., may cause the malfunction or failure of the turbine flow sensor, and directly cause the indication error of the turbine flowmeter. The error may be positive or negative, which may not be obvious or may be completely invalid. For the above phenomenon, when it is more serious, problems can be found from the comparison of the working status of the process, and it is easy to take corresponding measures. However, in the early stages of the problem, the problem cannot be detected without taking special measures. 2. Changes in fluid temperature and pressure may cause the liquid in the pipeline to escape the air contained in the pipeline, or because the pressure in the pipeline is lower than the saturated vapor pressure of the fluid, part of the liquid will become steam, or the negative pressure of the medium may cause the external air. The gas is sucked into the pipeline, and these gases flow with the liquid to be measured, causing the indication value of the instrument to increase, resulting in a positive error, which is unfavorable to the demand side of the fluid. 3. The fibrous or viscous impurities in the fluid are attached to the rotating part of the flowmeter, which increases the rotating resistance, reduces the indication value of the meter, and causes negative errors, which is unfavorable to the fluid supplier. 4. There are generally some impurities in the medium, which will cause wear on the bearing and shaft, so that the gap between the two will increase, the dynamic balance of the moving parts will be destroyed, the speed will drop, or the dirt will enter the gap, which will increase the movement resistance. , the speed drops. All of these reasons cause the display value of the instrument to decrease and negative errors to appear, which is unfavorable to the fluid supplier. The precession vortex gas flowmeter has built-in pressure, temperature and flow sensors, with high safety performance, compact structure and beautiful appearance. In-situ display of temperature, pressure, instantaneous flow and cumulative flow. Using a new type of signal processing amplifier and unique filtering technology, the interference signal caused by pressure fluctuation and pipeline vibration is effectively eliminated, which greatly improves the anti-interference ability of the flowmeter and makes the small flow rate have excellent stability. The unique time display and real-time data storage functions can ensure that the internal data will not be lost and can be stored securely no matter what the situation is. The power consumption of the whole machine is extremely low, and it can be powered by the internal battery for a long time. It is an ideal local display instrument without external power supply. The anti-theft function is reliable, with password protection to prevent parameter changes. The above is the whole content of this article.
