Description Specifications Optional Converter


The MEGAPD Oval gear flowmeter features two precisely machined rotating elliptical (oval) gears which rotate and mesh within the meter's interior housing in order to form a measuring chamber of known volume. The MEGAPD may be used to accurately determine volumetric flow rate as a function of the gears' velocity. The low cost MEGAPD provides good accuracy while offering reduced pressure drop versus traditional circular-gear type PD meters. The MEGAPD meter comes with a rugged battery-powered display module that indicates flow rate and totalized flows in user-configurable engineering units.
