ShareMEASUREMENT OF AIR FLOW RATES USING A SIMPLE PRESSURE COMPENSATING METER.
Author(s) : PHAFF H.
Type of article: Article
Summary
NOTES PROBLEMS WITH THE ACCURATE EVALUATION OF AIR FLOW RATES AT HVAC SUPPLY OR EXTRACT GRILLES USING FLOWMETERS WITH CONES OR HOODS. DESCRIBES HOW THESE PROBLEMS CAN BE OVERCOME BY COMPENSATING FOR THE PRESSURE DROP OVER THE FLOWMETER SO THAT THE PRESSURE ON THE DUCT SIDE OF THE GRILLE REMAINS THE SAME BEFORE AND AFTER POSITIONING OF THE FLOWMETER. TRACES THE DEVELOPMENT OF A SIMPLE PRESSURE COMPENSATING FLOWMETER AND ILLUSTRATES IT SCHEMATICALLY SHOWING THE MEASUREMENT PRINCIPLE.
