QY/RJNZ-1A Heat Meter Comprehensive Calibration Bench
- Parameters & Requirements
- Functions & Applications
QY/RJNZ series heat meter comprehensive calibration bench is R&D and manufactured by Chiyoung Instrument Co., Ltd. with the independent intellectual property. The bench is able to perform both heat meter calibration test and durability test. The bench can test various types of heat meters from DN15 to DN25, such as ultrasonic, mechanical, electromagnetic, and other types of heat meters. The bench is able to run combined verification test on flow parameter and temperature parameter separately. Also it is able to perform the complete verification test on various types of heat meter’s accuracy. Except for clamping the tested heat meter to the bench, the bench achieves automatic testing process: read measured standard parameters, read parameters of tested heat meters, error limit selection, error calculation of tested heat meters, and judgment of test results. There are two testing methods for the flow parameters calibration, which are standard meter method and weighing method. By using weighing method, the standard flow meter is able to achieve self-calibrate, which ensures the accuracy of the heat meter testing and improves test efficiency. The bench is equipped with the pressure loss test, the pressure test functions and other test functions. It is able to satisfy heat meter class II & III factory inspection and pattern approval test.
The test bench is according to EN1434-2014 “heat meter” European standard with 2400 hours durability test requirements. The durability test can automatically collect, display and save the real time and historical parameter information during the continuous operation process, such as time, flow rate, temperature, pressure of test, and etc. Historical data acquisition time interval is not more than 30s. Historical data can be exported to Excel format through USB or RS232 interface. There is GPRS (including GSM & TD-SCDMA) wireless data transmission port in the test bench, which is able to upload real time operation data and historical data to server through internet or GPRS. The bench achieves remote monitoring of unattended function through PC terminal or the mobile phone terminal. For the test location’s GPRS signal status is weak, the bench also has an INTERNET port to ensure the smooth of communication network. QY/RJNZ series calibration bench is featured with high automatic control functions, completed calibration functions, stable and reliable performance.
