2.3.3 Mounting the Top Fitting
It is recommended to use the Titan supplied 1” NPT top fitting. Alternative fittings must
not be longer than 1 ½”. Fittings exceeding 1 ½” in length with an internal diameter of
less than 4” interfere with the RADAR signal and prevent the TD80 transmitter from
measuring the liquid level or cause false level alarms.
Ensure that the probe hangs vertically in the tank, within 3 degrees of vertical. Tanks with
curved tops may require a leveling piece to meet the required vertical position.
