This is one of the few flow meters I could find which was rated for high temps. I'm using it to measure for in the hydronic heating loop from my outdoor wood boiler.One thing you must know is that this and nearly ever other flow meter on here are British standard pipe thread, BSPT, not NPT which is used in the US. The flow meter will not mate with us fittings. You need BSP to NPT adapters. Fortunately they are available here on Amazon.
