Mechanical Measurements


It is shown that it is possible to substantially increase the quantitative and qualitative characteristics of a flowmeter by reducing the fixed temperature level of the heat-transfer agent. A two-chamber design of a flowmeter is proposed and evaluated. A method of estimating the factual correctness of the results obtained by means of the flowmeter is presented.
