Flow Conditioning

Best Accuracy…

The inline QuadraTherm 780i has a built-in dual-plate flow conditioning element for greatly improved measurement performance, especially in installations where long straight pipe runs are not available.  The 780i is our most accurate thermal meter (+/- 0.5% of reading*) because it eliminates all velocity profile distortions as well as swirl and temperature stratification in the gas stream.

The 780i reduces piping straight run requirements to as little as three upstream diameters.  As a result, you save money on installation costs when compared to an orifice-plate solution where at least 20 upstream piping diameters are required for optimal performance.
