Ellipse® AHL Annular Flow Hot Tap, High Pressure Flow Meter

The Ellipse® Model AHL annular flow device is a hot tap, high pressure 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.

This product does not have the CE marking.
