JD - RNB - 1025 type thermal verification device
[Testing items]Used to test varioustypes of heat meter, and can complete the relevant test pattern evaluation ofcold water.
[Applicablestandards]
JJG225-2007Verification Regulation of Heat Meters
CJ128-2007Heat meters
JJG643-2003Verification Regulation of Flow Standard Facilities by Master Meter Method
[Features]
Devicedesigned reference to the latest national standards, to complete the overalltest heat meters, heat meters can be completed for each component of the test.Important original equipment used in the home are selected internationalbrands, an important instrument equipped with remote communication interface,reducing the bias in the data transmission process. Test the whole processusing computer control, the end of the test can be automatically generated testresults. Set all aluminum outer frame profiles installed splicing, elegantappearance.
Thedevice works: The device uses high-precision electronic called qualitystandards, electromagnetic flowmeters as secondary standards, with secondstandard platinum resistance thermometer and high-precision temperatureindicator as standard, with heated water tank as a standard temperaturedifference generating device.
Whenthe test according to the flow direction of the heat flow meter test series inthe pipeline, the water temperature rose to the required temperature, the heatmeter two temperature sensors were placed in two thermostatic bath. Adjust thepump frequency parameter and flow regulating valve opening, after switching thewater flow and temperature to be stable over time, recording the initial valueof each table, re-switch traffic to the test after the time to stop recordingcalorimeter end value, the data into the computer, the computer calculatedaccording to the formula specified in the standard error is automaticallycalculated error is detected table.
