They are used in velocity and air quantity calculation in turbulent ducts or environments.

Efficient and exact measurements before and after fan are performed with the Fecheimer probe.

The Fecheimer probes are used:

• In the measurement and balancing of the secondary air flow going to the windbox and burners
• In the measurement of the primary air going in each grinding
• In the flow calibration of the measurement devices like venturi and flow nozzles
• In the testing of the vectoral angular speed of the FD and ID fans

It is manufactured by the filled stainless material from 6" to 14".
