Note: Some flowmeters are shipped with sensors that have equal length elements (see Figure 2-2).
Others are shipped with the sensor elements that are offset (see Figure 2-3). The sensor type supplied
was selected at the factory to be the best suited for your application. Follow the appropriate sensor
orientation instructions below. (Refer to Figure 1-5)
a.
Install the compression fitting into the ¾-inch female NPT half coupling.
b.
When installing in a 2-inch pipe or larger, install the end of the probe 0.87-inch past the
centerline of the pipe and tighten the compression fitting nut. Refer to Figure 2-1.
c.
When installing into a 1½-inch pipe carefully install the probe into the pipe until it touches the
opposite wall and pull back 0.1-inch. Tighten the compression fitting nut.
Caution:
Once the compression fitting is locked onto the probe, the probe can be removed or
rotated, but the insertion depth is locked in place.
