2.4.2 Installation Procedure
The probe is threaded through a 1” NPT fitting at the top of the tank and sits in an anchor
cone at the bottom. It is not bolted in place, but sits approximately ½” above the bottom of
the tank and loosely inside the anchor cone, to allow for expansion and contraction of the
tank.
Prior to installation, ensure the tank is safe to work on as per precautions recommended
by the local regulations. See Section 2.1.1, Pre-Installation Requirements for details.
Step 1: Align and Weld the Mounting Fittings
1. Install the 1” NPT Top Fitting
a. Use the Titan supplied 1” NPT top fitting.
b. Make a hole in the top of the tank where indicated by the manufacturing or
installation drawings.
c. Ensure that the top fitting will allow the probe to hang vertically in the tank. If the
tank has a curved top, a leveling piece may be required. This will prevent the
probe from bending.
d. Ensure that the top fitting is aligned within 3 degrees of vertical above where the
anchor cone will be welded.
e. Weld the top fitting to the tank top, using a leveling piece if required.
f. Clean all debris from the threads of the top collar. This will prevent the probe
from jamming during installation.
2. Install the Anchor Cone
a. Use the Titan supplied anchor cone.
b. The anchor cone is required to prevent excessive flexing of the probe. The
anchor must be mounted directly in line with the top fitting to prevent bending or
