To define control valve inherent flow characterization and inherent rangeability, and to recommend allowable deviations from characterizations curves which are described mathematically or graphically.

No two flow measuring applications are the same, and two nearly identical flowmeter products can differ in how the accuracy is measured. Flow rates and flow totals are two of the key types of ...

LONG BEACH, Calif. - Pumps are responsible for a significant part of the world’s electrical energy consumption, but their impact can be by using variable-speed pump control, especially in hydronic ...
