Measurement Technology
The Digital Fluid-Trac™ DFT-110 drum level gauge
uses ultrasonic technology to generate a high-
frequency sound wave and measures the time for the
echo to reflect off the target fluid’s surface and return.
The distance from the Digital Fluid-Trac’s sensor to the
liquid is calculated based on the speed of sound.
The Digital Fluid-Trac™ DFT-110 has a LCD which
displays the liquid level pictorially as well as in gallon
(or liter) units. The display shows the level reading
from the last time the Refresh/Select button was
pressed.
When the Refresh/Select button is pressed and
released, the DFT-110’s back-light is illuminated and
8.8.8. is displayed for 4 seconds to indicate the unit is
in test mode. The unit continuously monitors the
media in the vertical drum for 7 seconds and then
displays the liquid level. The level reading will remain
static until the Refresh/Select button is depressed
again.
20 seconds after the button was pressed, the unit will
go into a battery saver mode where the back-light is
shut off. The liquid level reading will be displayed for
5 minutes before the display turns off.
.
A low level warning light (red LED located on the
bottom left of the LCD display), will flash once every
second when the liquid level is <= 10% the maximum
volume. Note: This warning light does not operate
once the unit has powered down in battery saver
mode.

Electrical Interface
The Digital Fluid-Trac™ DFT-110 drum gauge is
powered by two 9 volt batteries (not included). The unit
can run on alkaline or lithium batteries.
If the battery life is low (voltage is below 14.2 volts),
“LoB “ will continuously flash to notify the user to
replace the batteries.
Displaying the DFT-110 Setting
a) Press and hold the Refresh/Select button
b) Release the Refresh/Select button and the
down for 7 seconds. The drum size will be
displayed. and the selected units (Liter or
Gallon) will be flashing.
unit will automatically go back into test
mode (indicated by 8.8.8) in 20 seconds.
