- Abstract
Nowadays increasing the accuracy and reliability of measuring natural gas flow-rate is an urgent problem. In article is offered to increase the reliability of measuring the gas volume and flow-rate in a wide range of flow-rates by constructing a measuring complex with a few measuring devices based on different principles of action. The most rational structure of the device or complex with reduction the influence of elements on the output error signal can be selected by structural methods. The results of investigation of the natural gas flow-rate measuring complex and evaluation the level of mutual influence of the design parameters on the metrological characteristics of the whole complex are given. Particular attention is paid to determining the definite location of serial measuring devices along the length of the instrumentation system, which provides a minimum loss of gas flow energy and high accuracy of measuring its volume and volume rate. The optimal dimensional geometric form of the measurement node in measuring complex with different physical types of primary transducers will provide high accuracy and reliability of measurement in a wide range with minimization of pressure loss and flowmeters price.
