specifications
A+K Balanced Flow Meter was initially invented by NASA to measure liquid oxygen of the spacecraft and introduced from A+FlowTek company to Shanghai Keyontechs Co., Ltd.in 2006 Up to now, Keyontechs has produced more than 50,000 sets of BFM that are widely used in oil & gas, chemical, electric power, metallurgical and other industries at home and abroad.
A+K Balanced Flow Meter integrates the function of the rectifier and throttling sensor to meet the measurement requirements whatever under high temperature & high pressure, or low temperature or other severe working conditions. A+K BFM is also with short straight pipe requirement, high accuracy, wide application, low pressure loss and other excellent performance, wining great recognition from more and more customers.
Keyontechs has patented A+K Balanced Flow Meter and calibration laboratory approved by China National Accreditation Service for Conformity Assessment. Keyontechs always advances with the times, engaging in improving technology and service as pernational and industry requirements. By doing so, Keyontechs has won numbers of honers.
A+K Balanced Flow Meter is in conformity with lSO-5167 GB/T-2624,JJG640 standards and installation regulations of D/P flow meters.
