PRODUCT DESCRIPTION

Orifice ports are accurately machined for precision measurements. Each orifice plate has model number and orifice diameter stamped on tab for easy identification and selection.

Flange tap pressure drop readings determine flow on chart on page 3. Thin, square edge, bored orifice plates are installed between Pyronics “ADAPTO” flanges. Gaskets are provided to seal both sides of the plate. Meters should have at least 10 pipe diameters of smooth, clean, straight pipe upstream and downstream for accurate readings.

Orifice flow meters are ideal for measuring air and gas flows in combustion systems. Air-fuel ratio adjustment of burners is simplified when true air and gas rates are known.

Available accessories to be used with the orifice flow meters are the Model 5721 – 12” W.C. Manometer or the Model 5714 – Low Pressure Gauges for measuring pressure differential at the orifice plate.

In applications where corrosive gases are used or high humidity conditions are common, it is suggested that stainless steel plates be used. Petcocks and hose barbs are sold separately.

 

Note: Flow versus Pressure Drop Curves are based on gas flows (sp. gr. = 0.6) at zero line pressure and 60o F temperature.
