Measuring High Temperature Air Volocity

Measuring High Temperature Air Volocity

Measuring High Temperature Air Volocity

(OP)
How do I measure the high temperature air velocity in duct?

The range of temperature is 150(degree C)-300(degree C).

I found some high temperature air velocimetry such as Kanomax, Testo.

But that velocimetry are very expensive to me.

Is there any cheap method to measure air velocity of high temperature?

RE: Measuring High Temperature Air Volocity

Depends on what you call "cheap."

To echo CARF's post, we use pitot tubes and we instrument all portions of our engines, including HP turbines which are much much warmer than your range.
