Getting Started (continued) Step Two
Example #4 – Cone Bottom Tank
Tank G and Tank H are both vertical tanks that are
being supported above ground level with tank
stands. The location of the Sensor Height (Tank
G - bottom of tank or Tank H – ground level) will
influence the FILL-H setting.
Note: FILL-H must always be referenced to the
lowest location of the Sensor Height.
Since Tank G is off of the ground, the lowest
location may be difficult to identify/measure. This
location is required if the Volumetric Mode in
LVCN414-SW software is used.
Tank H uses ground level as the main reference
location. This method is easiest to use and ideal
for using the Distance Mode of LVCN414-SW
software.
Cone and Rounded Bottom Tanks
The location of an LVU700 series installed along the top of a cone or rounded bottom tank may have an effect
on the installation of the sensor. Be sure to understand the geometry directly underneath the sensor. Cone or
rounded bottom tanks will provide off angled surfaces that can reflect the ultrasonic sound energy away from
the sensor as the liquid level is lowered.

Geometry
Does not impede sensor’s
performance. Sensor is able
to track the entire range of the
tank.
Does not impede sensor’s
performance as long as the
level remains within the
straight side of the tank wall.
Does impede sensor’s
performance. The angled
bottom will reflect ultrasonic
energy away from the sensor.
Distance
Reading
HEIGHT is typically set to the
bottom of the tank. Sensor
will track the full range of the
tank.
HEIGHT is typically set to the
bottom of the straight side.
Sensor will only tack the
straight side of the tank.
HEIGHT is set to the bottom
of the tank; the sensor will
function as long as the level is
within the straight side of the
tank.
