INTRODUCTION The Series PFA FM approved fire pump system features the Preso Ellipse primary flow sensor. Preso's patented elliptical design outperforms and provides greater accuracy than traditional differential pressure flow measurement devices. This differential pressure flow meter is designed with a series of ports facing the upstream velocity pressures, as well as flow sensing ports strategically located ahead of the trailing edge flow separation.

GAGE MOUNTING 1. The FGE gage can be line, bracket or panel mounted. 2. For liquid applications the FGE should be installed below the PFA Ellipse in a level position. See Figure 6. NOTE: If recommended mounting is not possible, care must be taken to ensure that the gage is vented periodically. FLOW VENT VALVES...

PRESO ELLIPSE LOCATION INSTRUCTIONS Straight pipe requirements: Accuracy is affected by the piping configurations due to the disturbances of the flow profile. A fully developed symmetrical flow profile is achieved with the minimum upstream and downstream recommended lengths.
