1. General information
1.1 Intended use
The digital in-line meter is only suitable for operation with low viscosity, hardly ˜ ammable liquids.
The function of the electronics is guaranteed in a temperature range from -10 °C to +40 °C.
The in-line meter is pre-calibrated for use with fuel oil and diesel or AdBlue.
The intended use also includes an operation following the Operating Instructions.
Any use beyond these parameters or any changes can lead to serious risks and is regarded as use
that is contrary to the intended purpose. The operator is liable for any damage caused by improper
use.
1.2 Construction and description of function
The in-line meter is designed to be used for unproblematic liquid measurement.
The measurement recording of this in-line meter will be e° ected ˜ uidically based on the principles
of a turbine wheel ˜ ow meter. The measured values are transmitted packing- and contactless,
electronically processed and displayed.
The in-line meter o° ers an easy to read double-line display switching on automatically when
starting an operation or when pushing any button on the display keyboard. The ÿrst display line
shows the currently dispensed quantity of liquid. At the same time, the second display line counts
the total or a user-related or vehicle-related subtotal (1 to 9 subtotals available).
An automatic data storage is provided even when the battery will have to be changed.
The clear foil keyboard is easy to operate and is designed to be used for inputs of user parameters.
The complete display of the in-line meter is 4 x 90° rotatable so reading of the displayed
information is guaranteed in any position of installation.

4. Operation
4.1 Switching on the Meter
The meter is switched on by pressing the Start button. It displays the last measured value. When
starting a dispensing operation (recognised flow rate) the measurement will continue
automatically from the last measured value.
4.2 Resetting the Trip Counter to record a new measurement
The last measured value (large display) can be deleted by pressing the Reset button.
4.3 Displaying a Part Sum (subtotal)
Pressing the ▲▼buttons enables switching between TOTAL and part sums 1 to 9.
4.4 Resetting Part Sums and Total
Resetting Part Sums 1 to 9
By simultaneously pressing the Start and ▲ buttons for approx. 5 seconds, the displayed part
sum will be reset to 0,0.
Resetting the TOTAL sum
Unscrew the 4 screws at the back of the meter.
Carefully remove the meter cover with display from the housing.
Unscrew the 2 screws from the battery carrier.
Remove the batteries from the carrier.
Press the Reset button and at the same time insert the batteries back in the carrier.
The TOTAL sum will then be reset back to 000000.
Reassemble the meter in the reverse order.

4.5 Advice about Measurement Accuracy
The built in meter recognises, according to the operating conditions, the amount of fluid flowing
through it, and is factory precalibrated for use with heating oil and diesel fuel. The maximum
accuracy will be achieved when dispensing at a constant delivery rate.
However, various influences can affect the achievable measurement accuracy:
Viscosity and type of delivered fluid.
Strong pulsation and power variation of the delivery pump.
Installation conditions.
4.6 Calibration
By pressing both the ▲▼buttons for approx. 5 seconds the meter changes to calibration mode.
There are two possibilities:
Reading Current Calibration Value
To display the current calibration value, the Trip counter must first be reset to zero before changing
to the calibration mode. Do this by pressing the Reset button. When the calibration value is
displayed, the meter can be returned to normal operation, without changing the value, (last
calibrated value is retained) by pressing the Start button. Pressing the Reset button sets the
calibration factor back to the default value (factory calibration) and switches the meter back to the
operating mode.
Changing the Calibration value
By pressing both ▲▼buttons for approx. 5 seconds, with a trip counter value other than zero,
the meter changes to calibration mode.
By pressing the arrow button ▲ the value is adjusted upwards, by pressing the  button, the value
is adjusted downwards.
By pressing both the ▲▼buttons for a further 5 seconds the displayed value will be stored and
calibration finished. The meter switches back to operating mode.
Example: Dispense fluid into an accurate measuring container (20 litre volume).
Switch the meter to calibration mode by pressing the ▲▼buttons.
By pressing either the ▲ or ▼buttons, change the displayed value to match the amount in the
container.
Store the adjusted value by pressing the ▲▼buttons.
4.7 Switching off the Meter
The meter can be switched off by pressing the Start button for a long period (approx. 5 seconds). If
the meter is not active for more than 90 seconds, it switches off automatically.

5. Maintenance
As a matter of principle, the in-line meter is a low-maintenance product.
Based on the operator's obligations following parts should be checked regularly, in order to avoid
environmental damages or damages to property or persons.
The meter housing and the connections must be checked for damages and leaks regularly.
In case of a change of the battery, carefully open the meter housing and remove the battery as
shown above. Insert a new 3.6 V lithium battery (type SL 360S) and lock the housing.
