Installation & Operation Manual
I.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.
The multi-ported, self-averaging flow element consists of an elliptical shape with two independent flow sensing chambers. The
impact velocity sensing holes (high pressure) are located along
the leading edge and the true static sensing holes (low pressure)
are on the exterior probe side. Series PFA comes with instrument shut-off valves with provisions to accept a direct indicating
meter.

INSTALLATION INSTRUCTIONS - SINGLE SUPPORT
1. Choose the proper location to install the PFA Ellipse using AGA/ASME standards (or
equivalent). Refer to the Location Instructions on Page 8.
2. Grind the surface of the pipe where the PFA Ellipse is to be inserted to provide a clean area for
welding.
3. Weld the supplied weld-o-let to the pipe using standard codes for your application
(1/16” weld gap recommended). Take care to protect the threads during the welding process.
4. Drill a hole through the pipe wall according to Table 1.
5. Deburr the hole just drilled, especially on the inside of the pipe.

6. Install the supplied compression fitting by threading it into the weld-o-let manually. Then with
a wrench, tighten the fitting a further 1¼ turns taking care not to tighten the compression nut.
7. Install the instrument valves at the PFA Ellipse head connections. Ensure that the valves are
FULLY CLOSED to prevent them from leaking during start-up.
8. Insert the PFA Ellipse through the compression fitting See Figure 3. Carefully push the sensor
by hand further into the pipe until it reaches the opposite wall.
9. While holding the PFA Ellipse in its fully inserted position, align the arrow located on the sensor
head with the direction of flow. See Figure 4.
10. Thoroughly tighten the compression nut in order to prevent leakage. After tightening the
compression nut manually, turn it further 1¼ turns with a wrench.

INSTALLATION INSTRUCTIONS - DOUBLE SUPPORT
1. Follow Steps 1 through 7 in Section IV. At 180° from and on the same plane as the previously
drilled hole, grind the surface of the pipe to provide a clean area for welding. Drill a hole and
deburr, especially on the inside of the pipe. The hole used for the double support should be
sized according to Table 2.
2. Weld the double support weld-o-let making sure that it is centered with the drilled hole
(1/16” weld gap recommended).
3. Install the PFA Ellipse sensor through the two holes. Make sure that the double support pin
passes through the guide ring. See Figure 5.
4. Align the arrow located on the sensor head in the direction of flow as in Step 9, Section IV.
5. Ensure that the PFA Ellipse is in the correct orientation and spans the inside of the pipe.
Tighten the compression nut. After tightening the compression nut manually, tighten it 1¼
turns more using a wrench.
6. Install the plug into the end of the double support weld-o-let. Tighten the plug to prevent
leakage.

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.

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.

VII.
GAGE INSTALLATION
1. The connecting tubing between the PFA Ellipse and the gage should be as short as possible
and should slope down a minimum of 1 inch per foot.
2. Secure and support tubing to prevent sagging and/or vibration.
3. Care must be taken to ensure that the head heights are even.
4. A bleed line should be run from the gage vent valves to a pan or drain.
VIII.
GAGE OPERATION
1. Identify Hi and Lo pressure inlets on the gage.
2. Ensure by-pass valve (blue) is OPEN!
WARNING
WARNING: Gage may be damaged if initially pressurized with the by-pass valve closed.
3. Connect gage to corresponding Hi and Lo pressure taps of the PFA Ellipse (via 3-valve
manifold, if being used).
4. Open Hi and Lo instrument valves on the PFA Ellipse.
5. Alternately open the Hi and Lo vent valves to purge the lines.
6. When venting is complete, close the by-pass valve to begin taking reading.
