The Ellipse® Model AHZ annular flanged, hot tap steam flow device is a multi-ported, self-averaging differential pressure flow element. 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.
Multi-ported, self-averaging differential pressure flow element for saturated and super-heated steam applications
