Ellipse AHF Annular Flanged Hot Tap Flow Meter

Brand: Preso

The Ellipse Model AHF annular flanged flow device is a hot tap flow meter designed to produce a differential pressure that is proportional to flow. 

Its innovative elliptical shape provides the lowest permanent pressure loss in the industry. 

The Ellipse flow meter is designed with a series of ports facing the upstream velocity pressures and flow sensing ports strategically located ahead of the trailing edge flow separation.
