Flow | A+K
Balanced Flow Meter

Used in NASA's space shuttle program, A+K Balanced Flow Meter operates on a revolutionary, advanced technology for differential pressure measurement.

Key Customer Advantages

A+K Balanced Flow Meter adopts a unique flow measurement with minimum Reynolds number from 200 up to 10,000,000 with a steady and well conditioned flow profile. The flow meter's overall accuracy and performance is a vast improvement over traditional single bore orifice plate and other types of differential pressure device such as V-cone, pitot tube, Wedge element and Venturi tube. While retaining its structural simplicity, A+K Balanced Flow Meter has made a cutting-edge breakthrough in functionality and quality.
