The paper presents the results of a study of the error of a central water meter at different modes of water consumption. A stand has been designed for the purpose of the study and tests of the error of the water meter have been performed, in compliance with the requirements of Measuring Instruments (MID) Directive (2014/32/EU). The errors of the water meter have been determined in the area close to its start mode, which is not included in the area of inspection. The measuring errors have been also determined in specific operation modes with frequent starts and stops, associated with the flow of smaller water quantities. The study contains an analysis of the obtained differences in the accuracy of measurement during metrological verification of the water meter and reading on a real site. A quantitative estimate of the established losses in water metering is given.
