LY liquid flow Calibration system is designed and manufactured in accordance with JJG 164-2000 *Liquid Flow Standard Device*. It is suitable for the calibration of DN15–DN300 flowmeters using liquid as the measuring medium. The system integrates the LYZ static gravimetric method (DN15–DN300) and the LYB master meter method (DN15–DN1000), providing a purpose-built and targeted solution for accurate calibration of flowmeter performance.
