Influencing Factors Affecting Measurement Accuracy of Gas Ultrasonic Flow Meters

Abstract: The information on the influencing factors that affect the measurement accuracy of gas ultrasonic flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Nowadays, the calibration of ultrasonic flow meters for natural gas metering is carried out as far as possible on flow calibration devices. When using the calibration, can these parameters play this role, in the case of different values, or calibration? purpose of this study. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the articles that affect the measurement accuracy of gas ultrasonic flowmeters. Nowadays, the calibration of ultrasonic flow meters for natural gas metering is carried out as far as possible on flow calibration devices. When using the calibration, can these parameters play this role, in the case of different values, or calibration? The purpose of this study was to determine if the temperature of the fluid medium changes the pressure of the gas in the ultrasonic flowmeter. Now a device that can perform calibration of natural gas flowmeters, ultrasonic flowmeters, and flowmeters. Almost all of these devices, due to the use of natural gas flowing through pipes, under normal circumstances, it is possible to change the parameters that affect the speed of sound, temperature, pressure, gas composition, etc. may be. When using the calibration, can these parameters play this role, in the case of different values, or calibration? Also, by changing the temperature and the velocity of sound in the fluid medium, change if further experiments. (50°F) Natural gas at 21°C high temperature, 21 (70°F), 10°C nitrogen (70°F) for calibration experiments, 32°C (90°F). The effect of variation relative to the mean calibration curve, for each series of calibrations, was calibrated through. The flowmeter calibration satisfies the reproduction of the conditions that the ultrasonic flowmeter and the required device, the changes in the speed of sound, also do not respond to changes in temperature and pressure. When switching from natural gas to liquid medium for calibration, the slight observed change is due to the equation of state used for the two different gases. During the calibration of the ultrasonic flowmeter, the test results are set under the conditions as far as possible, and these indicate that the gaseous medium can be included in a further or different condition. By measuring the transit time of the ultrasonic gas flowmeter, the principle of ultrasonic measurement of natural gas is to deal with the relevant parties. The flow of ultrasonic waves in a consistent fluid is less than the direction of propagation in time. The difference in travel time of the gas flow between the two states is used to calculate the average velocity of the gas flow. This flow equation, which is independent of the velocity of sound in the gas flow (SOS), is only physical, as it contains the flowmeter's structural dimensions and travel time. Gas flow measurements are independent of factors that affect the speed of sound in gas temperature, pressure, and gas composition, such as: Therefore, by making assumptions, it is possible. It is worth considering a field of different operating conditions, and if this assumption is incorrect, the validity of ultrasonic flowmeter calibration. First of all, if there are several secondary effects in the ultrasonic flowmeter for measuring the speed of sound of gas independently, it may be due to the following reasons. Velocity, a specific specific gravity and viscosity, whether it is air or nitrogen, there is a possibility that some change in the properties of the gas, it is changing from natural gas. They are also considered as the inherent properties of the gas, which may vary, depending on temperature and pressure, but within the range of operating conditions, indicating that it is not so important to deviate from standard conditions is an overlap. The purpose of the described study was to determine the effects of temperature, pressure, and fluid media on ultrasonic gas flowmeters related to this article. In addition to ultrasonic flowmeter testing techniques, procedures are available to support the calibration of these gas flowmeters for the role of nitrogen or air. Currently, in North America, there are only two sets of equipment that can be used to calibrate the flow range of ultrasonic flowmeters with diameters greater than 200mm. The growth rate is more than 10% per year of flowmeter installations. In the future, calibration equipment has many limitations. The need for recalibration, the calibration of these devices may be less than a few years. For the calibration of ultrasonic flow meters, if the plant is limited in natural gas, the possibility of building new mobile equipment is limited by location and cost. However, if you can demonstrate calibration and other media, it is equivalent to building a new device, significantly increasing the likelihood. Air-calibrated gas flow meters are not just for ultrasonic flow meters. Almost all turbine gas flow meters are used for calibration and home gas metering. Gas calibration is naturally two, so the calibration device flow can be used to calibrate the air pressurized to test the same cycle, and nitrogen as an inert gas, the best choice,This is naturally nearby (including 78% nitrogen) air. There is (a part of the gas pipeline, isn't it) the Southwest Research Institute is a circulatory system, or you can use the same set of North American two nitrogen nitrogen in the same circuit, it is only suitable for gas testing is. In order to determine the mass flow rate of the calibrated device, the sonic nozzle unit is a measurement system, and the sonic nozzle flow calculation requires the equation of state to determine the gas composition and properties of the gas. In addition, we have decided to use a standard for the turbine flowmeter cycle to compare two volumetric flowmeters (eg turbine flowmeter and ultrasonic). This look-up table calculates the contrast of sonic nozzle wear from the gas composition.
