The BOILERWATCH MMP II acoustic pyrometer is an advanced industrial instrument that provides fully automatic measurement of high combustion-gas temperatures, permitting fuel trimming control within heaters. The system is completely non-intrusive, and operates on the principal that the speed of sound in a gas is proportional to the temperature of that gas.
In the link below, you can see a demonstration of the Acoustic Pyrometer System in a Delay Coker Furnace, which explains all the components of our technology in greater detail.
Best regrads.
