| description | The use of information-measuring systems at oil and gas enterprises allows improving gas consumption accounting. Of all the known methods for measuring flow rates, only the method of variable pressure drop has been studied in detail, developed and brought to standardized in full. The trends in the development of flow measurement technology in recent years make it possible to consider the ultrasonic method as one of the best, due, in particular, to the possibility of non-contact measurement of any substances, the reliability of transceiver elements due to the absence of moving parts, and, theoretically, an unlimited measurement range. The principle of gas flow measurement using an ultrasonic flow transducer is considered, based on the fact that an ultrasonic pulse directed along the flow propagates faster than an ultrasonic pulse directed against the flow. A procedure for calculating the gas flow rate reduced to standard conditions (P = 0.101325 MPa, T = 293.15 °K) is described. The paper considers a method for calculating the estimate of measurement error with limited initial information, when only the following metrological characteristics are normalized for measuring instruments: limits of permissible values of the basic error; limits of permissible values of additional errors at the greatest deviations of external influencing quantities from normal values, or the maximum permissible values of the influence coefficients. |
