Real-time determination of gas-quality parameters
With the Natural Gas Engine (NGE) function of the Fluxus G gas flowmeter series (photo), this company now offers the possibility of determining gas parameters, such as compressibility, molecular weight and density simultaneously with the flow in real time, enabling the meter to output the correct standard volume flow. The analysis function of the NGE is based on the measurement of the speed of sound — the same clamp-on transducers mounted on the outside of the pipe that are used to determine the volume flow by measuring the transit time difference simultaneously record the speed of sound of the medium flowing inside. The company has developed a self-learning algorithm that links the speed of sound with gas quality parameters. A series of tests in independent test laboratories confirmed the performance and accuracy of the NGE, for example, when measuring the flow of natural gas-hydrogen mixtures. — Flexim GmbH, Berlin, Germany
