2.1 Intended use
The DIT 01 digital tank contents indicator is exclusively suitable for
the measurement of filling levels in heating oil tanks with heights up
to 3 metres.
Any use other than the use explicitly permitted in this instruction ma-
nual in not permitted.
2.2 Predictable incorrect application
The DIT 01 digital tank contents indicator must never be used in the
following cases:
• Hazardous areas (ex)
2.3 Safe handling
The DIT 01 digital tank contents indicator represents state-of-the-art
technology and is made according to the pertinent safety regulations.
Each device is subjected to a function and safety test prior to ship-
ping.
 Operate the DIT 01 digital tank contents indicator only when it is
in perfect condition. Always observe the operating instructions,
all pertinent local and national directives and guidelines as well
as the applicable safety regulations and directives concerning
the prevention of accidents.
 The DIT 01 digital tank contents indicator is not a safety device.
It does not replace the function of a limit value transducer at the
heating oil tank.
 The DIT 01 digital tank contents indicator may only be installed
in unpressurised heating oil tanks. A tank vent installed in ac-
cordance with the pertinent regulations as well as a limit value
transducer are required.
 The cable entry point of the pressure sensor into the heating oil
tank must be significantly higher than the maximum filling level
and must be sealed with the enclosed screw connections in
such a way that no oil vapours can escape and that the pres-
sure sensor cannot move vertically
 The measured values displayed, especially the litre indication
values, must not be used for billing purposes. The accuracy of
the measured values displayed depends on the accuracy of the
tank data determined and entered. Therefore, the manufacturer
cannot guarantee the accuracy required for billing purposes.

3 Product description
The DIT 01 digital tank contents indicator consists of an electronic
pressure sensor and a microprocessor-controlled digital unit con-
tained in a sturdy plastic housing. The measured values are shown
on a 4-digit liquid crystal display (LCD). The function key F allows
you to switch on the device and select the display modes litres, cubic

Product description
metres, percentage and filling level. The device is programmed via
the two keys . A lithium battery is contained in the housing of the
digital unit. The battery is not connected when the device is shipped.
The free end of the cable is connected to the pressure sensor. The
pressure sensor and the digital unit form one unit. The pressure sen-
sor is placed in the tank from the top and is mounted either with a
connection and sealed.
The pressure sensor includes a spacer so that the measuring hole of
the pressure sensor remains above the oil sludge level.
Different screw connections are shipped with the pressure sensor
which are used to mount the pressure sensor cable to the tank and
seal it.

3.3 Function
The pressure sensor is located at the lowest point of the heating oil
tank and transforms the hydrostatic pressure of the heating oil into
an electrical signal. The measuring signal is transmitted to the digital
unit via the cable. The electronic system of the digital unit uses this
signal to calculate the tank contents, which it displays in litres, cubic
metres, percentage or filling level. The display mode is selected by
means of the F function key. The tank data is entered via the two
programming keys.

Mounting and commissioning
6.2 Mounting the wall holder
 Use the enclosed screw (4 x 30 mm) and, if necessary, a dowel
(6 mm) to mount the wall holder for the DIT 01 tank contents in-
dicator at the desired location.
6.3 Mounting the junction box
The provided moisture-proof junction box is not suitable for exterior
application.
1. For exterior application use the exterior junction box, refer to
chapter 11, page 23.
2. Use the enclosed screws and, if necessary, dowels, to mount
the junction box for connecting the pressure sensor cable and
the cable of the digital unit at the desired location. Make sure to
provide sufficient cable length. The digital unit must be able to
be removed from the wall holder, e.g. if you need to replace the
battery.
2. Place the digital unit into the wall holder and route the cable into
the junction box.
3. Push the connection elements required for the tank connection
(PG connection, screw connection or Euroflex) onto the pres-
sure sensor cable in the correct sequence and orientation.
6.4 Cable connection
1. Route the cable of the pressure sensor to the junction box and
connect the two cables by means of the insulating screw joint.
Make sure to connect the wires of the same colour, respectively.

Mounting and commissioning
4. A transparent tube can be seen at the cable end of the pressure
sensor. This tube provides the pressure sensor with atmos-
pheric pressure. Make sure not to close or bend this tube in or-
der to avoid incorrect measurements.
The junction box must be closed in such a way that it is water-
tight but not completely airtight.
6.5 Connecting the battery
1. After you have electrically connected the pressure sensor and
the digital unit, open the housing of the digital unit by turning the
upper part of the housing all the way to the stop and pulling it
up.
5. Press the miniature button (1) and keep holding it down. Plug
the 2-pole battery plug into the 2-pole socket (2) on the printed
circuit board.

WARNING
Danger of explosion in case of short circuit of the lithium bat-
tery.
 Do not short-circuit the lithium battery.
6. Release the miniature button.
6.6 Zero balancing
1. Close the housing of the digital unit by pushing the two housing
parts together.
Since the battery was connected, the digital unit was switched on.
The display switches between "Zero" and the current offset of the
pressure sensor (indication in hPa = mbar). The top left corner of the
14 DIT 01

Mounting and commissioning
display shows the arrows  to indicate that you are in calibration
mode.
7. Press the keys and simultaneously to correct the offset to
the value 0.00.
When you do this, the pressure sensor must not be in the
tank.
In this state, you can zero the system any number of times.
8. Press the F key in order to exit the zero balancing mode.

An arrow is shown at the bottom of the display pointing to the
unit Litres.

Mounting and commissioning
12. Move the cable in the connection until the probe tip just reaches
the tank bottom. The measuring hole of the pressure sensor
must not be immersed in the oil sludge. The oil volume below
the level of the measuring hole is not detected by the pressure
sensor.
13. Insert the withdrawal hose after you have inserted the pressure
sensor.
Fig. 7: Inserting the withdrawal hose
14. Seal the connection in the tank cover to make the connection
smell-tight and tighten the connection to prevent the cable from
moving.
Mounting with screw connection
Using a free 1", 1½" or 2" connection in the tank:
1. Insert the cable of the pressure sensor into the 1" screw con-
nection and use parts of the 2“ x 1½“ x 1 “ screw connection set
to seal it in the tank.

Mounting with PG 9 connection
In an installation flange with union nut, in a screw cap or in a free
blind connection:
1. Remove the installation flange, the screw cap or the blind con-
nection and drill a 15 mm hole.
Never drill directly into the tank.
When drilling, make sure that chips do not fall into the tank.

1. Lower the pressure sensor into the tank.
19. Determine the required cable length as described above.
20. Tightly screw the black plastic screw (pressure screw) into the
body of the Euroflex fitting. This applies pressure to the two
O rings between the cable and the body of the Euroflex fitting,
fixates the cable and assures a pressure-tight connection.
