2.3 BUSHING OR FLANGE MOUNT METHOD FOR ALL TANKS
This method is recommended for DEF tanks with standard 2, 3 and 4-inch openings. The level probe
will "hang" inside the tank at a fixed position supported by the tank-mounting fitting. This will protect
the purity of the DEF by reducing the number of wetted materials.
Because the probe is fixed to the mounting fitting, it is critical during installation to allow a 1-INCH
BOTTOM CLEARANCE between the probe's FOOT REST and tank bottom or strike plate. This will
prevent the probe touching the tank bottom during tank expansion and contraction. The 1-inch
clearance dimension is standard and has been properly accounted for in the probe's manufacture.
The customer must supply an appropriate mounting fitting to mate with the tank opening, if less than
2 inches, to accommodate the PK2-DM3 Direct Mount Probe Kit. Assembly is as illustrated in Figure
2-5.
Figure 2-4 - Reducer Fitting or Flange Mounting for Aboveground Tanks
Install the level probe per Figure 2-4 as follows:
1. Select the correct probe for the tank. Match the model number with the tank internal dimensions
per Figure 1-4.
2. Remove the probe from its shipping container. Remove all packing material.
3. Slowly lower the probe into tank opening. The probe should be vertical with its electronic housing
totally visible above the tank fitting. When the probe touches the bottom, screw the bushing into
the tank. DO NOT tighten the compression fitting at this time. Mark the shaft and lift the probe up
1 INCH.

2.6 LEAK SENSOR INSTALLATION IN FIBERGLASS TANK ANNULUS
The annular space of fiberglass tanks can be fitted with either a "DRY ANNULUS" type sensor,
models ES825 (Figure 1-6) and LS610 (Figure 1-7), or a "WET RESERVOIR" sensor model RSU800
(Figure 1-8). The wet reservoir is also referred to as the HYDROSTATIC METHOD. Check the
specific design drawings for the job, or choose the type sensor desired from Figures 1-6 through 1-
8. Install sensor per Figures 2-8 or 2-9.
Instructions per Figure 2-8, DRY ANNULUS SENSOR:
1. Calculate the sensor cable's MOUNTING LENGTH from tank size data so the sensor rests at tank
bottom; or use the following method.
Determine the cable's MOUNTING LENGTH by
adding the cable measurement M from the table at
the right to the RISER HEIGHT. Mark the cable at
that length. DO NOT CUT THE CABLE.
2. Remove the watertight CORD CONNECTOR
supplied by sliding it off the cable.
3. Thread the CONNECTOR into the top of a 2" by
1/2" reducer bushing or riser pipe cap pre-tapped
for a 1/2" NPT hole. (The use of any standard
monitor capfrom 2" to 4" pipe size is recommended.
The cap orreducer bushing ISNOT SUPPLIED with
the sensor and must be provided by the installer).
4. At riser top, attach the annular space PULL CORD
(this is part of the tank supplier's pre-installed
accessories) to the sensor's PULL HOLE.
5. Pull the free end of the PULL CORD out of the riser while feeding the sensor into the riser and
through the annular space until the sensor is at the bottom centerline of the tank. The MOUNTING
LENGTH MARK should be about 5INCHES above the open riser. Adjust its position asnecessary
and, without disconnecting the PULL CORD, coil its excess inside the riser pipe.
6. Feed the sensor cable through the BOTTOM of the riser cap (or bushing), and through the CORD
CONNECTOR while positioning cap over the riser pipe. Mate riser and cap.
7. Tighten CONNECTOR over the cable to ensure a WATERTIGHT SEAL.
