• One of the few domestic enterprises with both large liquid calibration device and gas calibration device
• Obtained the device verification certificate issued by China Academy of Metrology
• Certified by CNAS(China National Accreditation Service for Conformity Assessment)
• Designed and contracted the expansion and renovation project of calibration devices of Jiangsu Metrology Institute and Nanjing Metrology Institute
Liquid calibration Device:
• The diameter is DN3-DN2000. The maximum flow rate is 9000m /h, the extended uncertainty is better than 0.05%, and the maximum precision can be calibrated with the accuracy of 0.15%.
★ Gas calibration Device:
• the sonic nozzle negative pressure method was adopted to calibrate the maximum air volume up to 7000m /h, with an accuracy of 0.33%.
• The translational commutator independently developed and designed by the company optimizes the track structure, reduces the noise and uncertainty of the device by cylinder pushing, and has obtained equiption-related technology patents.
These two sets of calibration devices can ensure the accuracy of factory calibration of each flowmeter and the calibration results can be traced globally.
