Xylem EX100/200-Series ELECTROMAGNETIC FLOW SENSORS - Manual (Page 6)

Depth Setting. It is important for accuracy that the sensor
be inserted to the correct depth into the pipe.
1. In Table 1, find Dimension C for your sensor model
and pipe size. Subtract wall thickness of your pipe
(Table 2) to find Dimension D.
NOTE: When you calculate your K-factor as described
on page 12, Dimension D will be given also.
2. Measuring from the outside of the pipe to the joint in
the housing, as shown in the diagram, adjust the
sensor to Dimension D and hand-tighten compression
nut.
3. Align the conduit housing with the centerline of the
pipe, as shown. Be sure the arrow on the housing
points in the direction of flow.
4. Check Dimension D one more time.
5. Tighten the compression nut fully.

INSTALLATION
Caution! Never attempt to remove a flow
sensor when there is pressure in the pipe
unless it is specifically designed for hot
tap installation and removal. Loosen the
compression nut slowly to release any trapped pres-
sure. If fluid sprays out when removing the sensor,
stop turning and depressurize the pipe. Failure to
do so could result in the sensor being thrown from
the pipe, resulting in damage or serious injury.
