Final sensor band screw tightening is as follows:

A. For sensor bands sized for 6” and smaller pipe:

1. Tighten screws #1-7 an additional one-half turn in the numbered

sequence given in Figure 8. Do not tighten screw #8 & 9 (screws
on either end of the sensor band).

B. For sensor bands sized for 8” and larger pipe:

1. Starting at screw #1 in Figure 8, tighten each screw an additional

one-half turn in the given numbered sequence.

2. Once all nine screws have been tightened, tighten each screw an

additional one-half turn in the given numbered sequence.

3. Once all nine screws have been tightened a second time, tighten

screws #1-7 an additional one-half turn in the given numbered
sequence.

Attach the sensor cable in the retaining clip on the top of the sensor
band. The connector on this cable will attach to the sensor cover
connector as described later in the manual. If necessary, use a piece
of tape to temporarily retain the connector on the band so it will be
positioned directly below the sensor cable access panel. The final
sensor band assembly is illustrated below.

Over-tightening of fasteners may damage threads on the sensor.
Under tightening may affect flow meter performance. Always
use the sensor fastener spacer tool to ensure proper fit of the
