We have those, Dave. But if you get coating on the tubes in the heat exchanger, flow through the tubes misleads you.

() I completely agree that a flow sensor will give you a first line of defense. At any decent RPM level, interupted flow gives you a minute or so. Once the audible alarm goes off, the engine is too hot and damage can be done in a remarkably short period.
As I experienced first hand -- you can have "clear" tubes, good flow, but if your heat exchanger has deposits in it, then the only thing is to have it ULTRASONICALY CLEANED.
I believe the only reason to measure EGT (exhaust gas temperature) is not really protect from over heating, it's to optimize the loading and RPM.

- Mostly useful for turbo engines
- have seen these in the Hamilton Catalog
- I think a water flow...
- Do you have a controllable pitch prop?
- What is your purpose?

- Thanks for all the comments. We will not spend money on an exhaust temp gauge
