6511 – SONDE MOUNT KIT FOR 6OO SERIES SONDES
The 6511 Sonde Mount Kit enables a 600 Series Sonde to be deployed in a permanently mounted
two-inch schedule 40 PVC tube, which is not
included in kit, approximately 10 feet in
length. The tube is mounted to 1-1½”
diameter railing by included brackets and u-
bolts. The sonde will be deployed by gently
sliding it down the tube, where it will rest on
a stop cap at the end of the tube. The probes
and probe guard will protrude through a hole
in the stop cap at the end of the tube.
The 6511 Kit should not be mounted on hot
or vibrating pipes or structures, or near high
heat sources, AC motors or transformers,
radio transmitters or antennas.
Do not mount on electrical conduit.
Avoid routing Sonde cabling near wiring
associated with rotating machinery and/or equipment involving electrical switching or regulation.
Consider placing Sonde cables in grounded metallic conduit if unstable readings appear due to
electromagnetic interference.

The following steps should be followed when rail mounting the 6511 Sonde Mount Kit.
1. Using the Stop Cap as a guide, see Figure 24, position the adapter on the sonde so that the
probes, ports, and guard will protrude through stop cap when deployed, and securely tighten
set screws.
Note: Do not over-tighten the set
screws or damage to the sonde
body or adapter may occur.
2. Attach the stop cap to the end of
the PVC pipe using PVC cement,
as per instructions on cement can
label, ensuring that the stop cap
is positioned straight and the pipe
is fully inserted.
3. Loosely fasten two 1½” u-bolts
on each mounting plate to the railing, orientated as shown in Figure 25.

5. Slide the uncapped end of the PVC pipe up through the 2” u-bolts until there is
approximately 1” of the PVC pipe above the upper mounting plate, and tighten 2” u-bolts.
Note: Do not over tighten u-bolts or deformation of the PVC pipe may occur.
