Improve the accuracy of the mass of gas test flowmeter order to obtain reliable characteristics of components and assemblies characteristics of the liquid rocket engines
Abstract
A method of definition of sensitivity threshold and a way of instability elimination of a weight-measuring device balancing of a facility for gas flow meters calibration by weighting are presented in the paper. Instability balancing in the range of weighed gas masses of 1.5-18 kg will be from 0.13 to 0.011%. So, to increase the measurement accuracy of the gas flow rate, the calibration duration and gas mass in a gas inlet vessel should be increased to the maximum possible values. The accuracy in determining the device characteristics to be calibrated will not exceed 0.25%, which is significantly lower than the existing methods.
