FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment and can be used to calibrate and test pipeline systems for measuring and recording of thermal energy and liquid and water meters. Proposed is a method for calibrating measuring heat energy accounting systems and testing liquid meters directly on the site of their operation is based on connecting a reference measuring devices to pipelines of heat carrier with the help of valves, temporary stabilization of flow parameters and comparing the calibrated system readings with reference values. Heat carrier flow from the supply pipeline through a reference means onto return is additionally directed through tested liquid meters. Liquid meters are tested simultaneously with calibration of meters of thermal energy and heat carrier.
EFFECT: technical result - increase of performance of metrological operations of thermal energy and water in operation.
