Kaifeng Instrument Co., Ltd. (KFI), built up in 1958,was directly under the administration of the former ministry of Machinery Industry.After 60 years of development,KFI has become the largest manufacturing and testing base in China for flow meters.
The National Water Large Flow Rate Metering Station, the No.13 Measurement and Test Center Station and The Quality Inspection and Supervision Center for Flow Meter of Machinery Industry are all established in our factory. Among which, the National Water Large Flow Rate Metering Station has been authorized by the State Bureau of Quality Technical Supervision as a national legal metrological verification organization to calibrate and certificate the water large flow rate flow meters all over China. KFI has established the most complete flow standard verification facilities in China,including large,medium,and small-sized real flow proving facilities and test equipment for water,gas and oil flow.
KFI’s factory covers over 180,000 square meters, There are more than 600 employees, including 180 engineers and technicians. In the past 60 or more years, KFI have developed and more than 4,000 specifications of industrial automation instruments.
Our factory has 6 workshops, 12 production lines, over 200 operators, equipped with high-precision CNC machine tools and complete facilities for quality inspection and flow calibration.
Kaifeng Instrument CO.,LTD(KFI )is well equipped with measurement and test devices. There are standard devices of large median and small flow rate for water gas and oil, which provide assurance for the product development design and test. All the flow standards are designed and manufactured by KFI, whose performance have reached the advanced level in China.
