DFT-110 Product Overview
Product Overview
Digital Fluid-Trac®Model DFT-110 multi unit drum level gauge is a cost competitive non-contact liquid
level drum gauge. The DFT-110 drum gauge was designed for usage on ANSI MH2-2004 vertical drums
(≤ 32 inch depths). The DFT-110 drum gauge allows the user to easily select between the following
vertical drum settings: 15 gallon, 30 gallon, 55 gallon, 57 liter, 114 liter, and 208 liter.
Product Features
• Display Resolution: ± 0.5 gallon or ± 1 liter *
• Accuracy: ± 2.5% (1.5 gallons or 6 liters) of full scale volume (55 gallons / 208 liters setting) *
• Automatic Shuto󰀨 Prolonging Battery Life
• NEMA 4 Packaging
• Static Display Useful for Usage Consumption Calculations: The static level reading can be used
for manual rate calculations – i.e. daily or weekly consumption.
• Low Level Warning Light: A red LED will ash once every second when the volume is at 10% or
below the maximum volume.
• Easy to install: Digital Fluid-Trac®DFT-110 has no components to protrude into the drum.
• Standard: Fits 2” NPT or ¾” NPS opening
• Deadband: 6” from top of barrel when using the optional ¾” adaptor
• More Reliable: No components to chemically corrode inside liquid media.
• Chemical compatibility: Digital Fluid-Trac® DFT-110 drum gauge works with a wide variety of media
such as water, waste water, motor oil, hydraulic uid and diesel fuel.
Note: The Digital Fluid-Trac™ is NOT intended for use with gasoline or other volatile liquids that produce
a vapor pressure under normal operating temperature (0 °C - 50 °C).
* Outside of stated dead band.

Measurement Technology
The Digital Fluid-Trac® DFT-110 drum level gauge uses ultrasonic technology to generate a
highfrequency sound wave and measures the time for the echo to reect o󰀨 the target uid’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 backlight is
shut o󰀨. The liquid level reading will be displayed for 5 minutes before the display turns o󰀨.
A low-level warning light (red LED located on the bottom left of the LCD display), will ash 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 V batteries (not included). The unit can
run on alkaline or lithium batteries.
If the battery life is low (voltage is below 14.2 V), “LoB “will continuously ash to notify the user to
replace the batteries.
Displaying the DFT-110 Settings
1. Press and hold the Refresh/Select button down for 7 seconds. The drum size will be displayed.
And the selected units (Liters or Gallons) will be ashing.
2. Release the Refresh/Select button and the unit will automatically go back into test mode
(indicated by 8.8.8) in 20 seconds.

Selecting the Display Units
The Digital Fluid-Trac® DFT-110 multi-unit drum gauge can set to display the level reading in one of six
di󰀨erent congurations - gallons (15, 30, 55) or liters (57, 114, 208).
1. Enter the Select Mode: Press and hold the Refresh/Select button down for 7 seconds to enter the
Select Mode. The unit will display Liter and Gallon. One of the units will be ashing.
Note: If you release the button too soon, the DFT-110 will be in test mode.
2. Switch the Desired Units: Press and release the Refresh/Select button to switch between the units.
3. Select the Desired Units: When the units (Liters or Gallons) desired is ashing, press and hold the
Refresh/Select button for 7 seconds to select the units. The units will stop ashing and the drum size
will start ashing.
4. Switch the Desired Drum Size: Press and release the Refresh/Select button to switch between
the drum sizes.
5. Select the Desired Drum Size: When the drum size desired is ashing, press and hold the
Refresh/Select button for 7 seconds to select the drum size. The drum size will stop ashing.
6. Return to Test Mode: Press and hold the button until 8.8.8. is displayed – this indicates test mode.
Testing With the DFT-110
1. After you have selected the proper units and drum size for your application, Press and release the
Refresh/Select button.
2. 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.
3. The DFT-110 continuously monitors the media in the vertical drum for 7 seconds and then displays
this liquid level.
4. Battery Saver Mode: 20 seconds after the button was pressed, the back-light is shut o󰀨. The static
liquid level reading will be displayed for 5 minutes before the display turns o󰀨.
Note: This liquid level displayed is a static value. You must depress the Refresh/Select button to up-
date the liquid level reading.
5. A low-level warning light (red LED located on the bottom left of the LCD display), will ash 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.

Mounting
Digital Fluid-Trac® works well on ANSI MH2 standard 55 gallon drums as it mates with closedhead
standardized bunghole arrangements. The 55 gallon drum gauge mounts on top of the drum with a
standard 2” NPT thread connector. A ¾ inch NPS threaded adapter is included with each
Digital FluidTrac® Model DFT-110 so either bung opening can be used on the drums.
When using the Digital Fluid-Trac®, it is important to keep the mounting perpendicular to the liquid level
by storing the drums in an upright position.
