Improvement of metrological reliability in the measurement of coolant flow and the amount of heat at housing and communal facilities

Abstract

The authors examine dynamic and metrological characteristics of a vortex-acoustic flowmeter, a classification, a brief description, and the operation principle of widely used flowmeters. They present the results of research and exploitation of vortex-acoustic and electromagnetic flowmeters within the calibration interval (CI), obtained on an automated laboratory research test bench. The authors give some practical advice on choice of devices for flow metering based on the procedure of metrological reliability.
