Kaifeng Instrument Co., Ltd. has strong advantages in the development and production of pipe provers and has decades of experience in the design and manufacture of the various specifications of pipe provers.

 

Long history, great influence, and complete specifications


The pipe prover is a standard device for large-flow field liquid flowmeter verification, it is developed in the past 60 years. As early as the 1970s, our company successfully manufactured the first Chinese domestic set of DN600 one-way one-ball valveless pipe prover flow calibration device for the Huang Dao Oil Terminal, with a maximum flow rate of 3000m3/h. The completion of this device has established our company's leading position in the flow instrument verification industry. Over the past 30 years, our company has designed and manufactured more than 100 sets of standard volumetric flow calibration devices and pipe provers for users, which are used in major oil fields, pipeline companies and refineries across the country.
