Ellipse® PFA Fire Pump System

The Model PFA FM approved Fire Pump System features the Preso® Ellipse®. The Ellipse is a primary flow sensor designed to produce a differential pressure that is proportional to the flow. Its patented elliptical shape provides the lowest 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. As a result the Ellipse is capable of highly accurate, precise flow measurements that are proportional to the actual flow rate.
