Badger Meter Annular Round Model PFB - Manual (Page 3)

INSTALLATION INSTRUCTIONS
• The primary station can be installed in any position on vertical or horizontal lines. However for best results on horizontal
liquid lines where the risk of air/gas entrapment in the water tubing is prevalent, install element with the head under the
horizontal center line.
• The Preso primary element is bidirectional. However, make sure head is parallel to the pipe run.
• For pipes measuring 1-1/4" primary element, MNPT and may be installed in any direction.
1. For pipes 2…6":
a. For pipes measuring 2…4", drill a 3/4" hole into the pipe. For 5…6", drill a 5/8" hole into the pipe.
b. Weld the coupling to the pipe in line with the hole.
c. Pass the probe through the packing gland and insert it into the pipe through the coupling. Tighten the hex nut to
the coupling.
d. Push the probe until it touches the opposite side of the pipe and tighten the hex nut of the packing gland.
2. For pipes 8…16":
a. For pipes measuring 8…10", drill a 1/2" hole on the side where a reading will be taken and a 13/32" hole on the other
side. For 12" pipes, drill a 5/8" hole on the side where a reading will be taken and 17/32" hole on the other side. For
14"…16" pipes, drill a 7/8" hole on the side where a reading will be taken and 25/32" hole on other side.
b. Weld the coupling to the pipe in line with the hole, making sure it is in line with the opposite hole.
c. Pass the probe through the packing gland and insert it into the pipe through the coupling. Tighten the hex nut to
the coupling.
d. Push the probe through the pipe until it passes through the opposite hole to ensure alignment.
e. Withdraw the probe and weld the other coupling to the pipe.
f. Push the probe through the packing gland until it enters the other hole and is flush with the outside wall of the pipe.
Tighten the hex nut of the packing gland.
g. Install the pipe to the coupling.
