FIELD: instrumentation.SUBSTANCE: claimed process relates to calibration of heat power and heat carrier measurement system. This process consists in temperature calibration with the help of a thermostat, disconnection of consuming hardware from heat lines and connection of master meters of feed flows to heat carrier pipelines. Besides, it comprises the comparison of calibrated system readings with master means and the allowance for differences in the readings of flow rate, heat carrier amount and temperature of calibrated measurement system in feed and return pipeline. Working thermometers are connected to thermostat via equalised extension leads. Flow rate channels are calibrated at every points of stabilised temperature to construct the temperature and flow rate graphs for several temperatures and several flow rates at every temperature magnitude.EFFECT: higher validity of measurements.7 dwg, 2 tbl |
