1. Attach the saddle to a section of pipe that has at least 10 diameters

of straight pipe ahead and five diameters of straight pipe behind the

saddle. Drill a minimum 1 1/8” diameter hole in the pipe.

2. Remove the sensor assembly from the mounting hardware by loosening

the hex cap over the stem collar and the cover to the mounting adapter

and detaching the assembly. Set aside taking care not to damage im-

peller/shaft assembly.

3. Attach the pipe thread end of the mounting adapter to the saddle/weld-

o-let using a pipe joint compound and tighten the joint. Do not apply

sealing compound to the top thread of the mounting adapter. It is sealed

with an o-ring.

4. The sensor rotor assembly is to be located a fixed distance from the

center of the pipe. To position the impeller at this depth, a reference

measurement for the pipe size and schedule is used. Look up the pipe

size and schedule number in

Table A and note the reference number.

Next, measure from the outside wall of the pipe to the top of the installed

mounting adapter “B” in Figure 3. Add this number to the reference mea-

surement.

The resulting number, “C” in Figure 4 is the distance from the recess of

the sensor tip to the bottom of the stem collar. Insert the metal tab of

a tape measure into the recess of the flow sensor tip. Extend the tape

up the stem and mark the shaft with a pencil. Slide the collar along the

shaft until its bottom surface is at the mark on the stem. Tighten the cap

screw on the collar. When the sensor is reassembled, this will set the

insertion depth of the sensor.

5. Attach the sensor to the mounting adapter by gently pushing the flow

sensor into the mounting adapter until the cover touches the mounting

adapter. Tighten the cover against the o-ring seal. This will seal the

sensor assembly.

6. Continue to insert the flow sensor stem until the stem collar meets the cover. Thread the hex cap onto the mount-

ing adapter but don’t tighten. Align the flow sensor with the pipe by using the flat cover on the electronics hous-

ing as a guide. Place a straightedge along the cover and rotate the sensor until the straightedge is parallel with

the pipe. Tighten the hex cap over the collar approximately 10 foot pounds. The hex cap holds the sensor align-

ment but performs no sealing functions. DO NOT OVERTIGHTEN.

7. Pressurize pipeline and check for leaks.
