Turbine Flow Meters

Technology-of-Choice for Measuring Critical Fluid Flow Applications

The aerospace industry has some of the most difficult operating conditions imaginable. Sensors of all kinds used in this industry must stand up to the environment and be able to perform under harsh conditions, fit in extremely tight spaces, and have electronics that can compensate for variable conditions in order to provide precise, repeatable results.

In particular, flight instruments measuring fluid flow in aircraft fuel and hydraulic systems are required to operate over extreme temperature ranges, while enduring heavy vibration and shock, and withstand electromagnetic interference and voltage transients. And, as aerospace test environments become more severe (higher temperature, greater vibration) and test application requirements for measurement devices grow more stringent (smaller, lighter, more stable, higher accuracy), obtaining meaningful data can be challenging.
