Installing the Baseline PFS Flow Sensor in the Pipe
Important!
Depressurize and drain the pipe before installing the sensor.
Disassemble the PFS Flow Sensor
2. Remove the tapered wedge from the side of the saddle
and fold the bottom half of the saddle down to separate it
at the hinge.
1. Turn the retaining nut on the PFS flow sensor insert counter-
clockwise and pull the insert housing straight out of the tee.
Do not pull on the wire leads!
Prepare the Pipe
Attach the PFS flow sensor to the outside of a section of PVC pipe with the same nominal size as
the saddle after an entry hole for the sensor insert has been drilled through the pipe. Use best
industry practices to insure that the sensor is installed correctly.
1. Locate a straight section of pipe with a minimum of 15 diameters of straight pipe. Clean a
12” (minimum) section of pipe 10 diameters downstream of any valve, fitting, or change in
size.
2. Use a 1 ¾” hole saw, NEITHER SMALLER NOR LARGER, to drill the entry hole in the center of the
cleaned area of the empty depressurized pipe. Make sure the hole is perpendicular to the
pipe and centered. Remove the pipe coupon with the saw; do not allow it to fall into the
pipe. Remove the burr from the edge of the hole.
