Purpose - to hold potassium edge flow "CMX" on hydrodynamic stand IPMash NAS in two positions flowmeter installation. Calibration was carried out on a liquid flow rate mode from 33 to 510 l/s. The values obtained were compared with the values of the electromagnetic flowmeter IPMash. At work the following tasks have been solved: - - the calibration of the flowmeter 160 mm diameter at two embodiments dimensional tube installation: downward angle of 45º to the horizontal; 45º upwards at an angle to the horizontal. Calibration was carried out at flow rates 26-269 l/s. When spills flowmeter measuring tube installed downward relative measurement error does not exceed 1%. When spills flowmeter tube set up relative measurement error exceed a value of 1% . This is explained by the presence of air in the pulse tubes submerged of "Safir" sensors; - the calibration of the flowmeter 400 mm at flow rates of 150 - 540 l/s. During calibration on preliminary tests determined correction coefficient. On receiving the results of tests measuring the costs do not exceed 1%.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
