3. Intended conditions of use
This oval gear meter has been designed and developed for the precise measurement and registration
of volumes of varous media featuring dierent viscosities such as DEF, diesel and heating oil.
3.1 Design and functional description
The oval gear meter/pulse meter is a uid meter with electronic counter and digital display.
The medium owing through the meter sets a oval gear in rotation. The revolutions of the gears are
converted into electronic pulses and sent to the electronic counter by a Reed switch. The electronics,
nally, uses a certain multiplication factor to convert the pulses into an intelligible volume of liquid
having gone through the device, which is then shown on the LCD display.
The multiplication factor has been pre-set at the factory using an average that has turned out to be
useful in normal operation. However, it can be easily adapted to specic requirements by the user.
The total volume measured is stored and can be called up by pressing the TOTAL button.
The user needs only two membrane key switches for operation: RESET and TOTAL (total volume).
The body of the device is made of aluminium. (DEF version made of stainless steel).

TOTAL BUTTON
The electronic components and LCD display sit at the top of the oval gear meter, well insulated against
the wet measuring chamber. There is a cover to protect them against the working environment.
3.1.1 LCD display
The meter‘s LCD display is equipped with two numeric registers and dierent types of display modes
showing information to the user only when it is actually needed with the operation / function going on
at the moment.
Key:
1. Register of partial volume (5 digits with oating decimal: 0.000+99999) showing the amount of liquid
that has been delivered since the RESET button was last pressed
2. Battery charge
3. Display of the calibration mode
4. Register of total volume (6 digits with oating decimal 0.0-999999x10/x100) showing two dierent
kinds of total volumes:
4.1 Non-resettable total volume (TOTAL)
4.2 Resettable total volume (RESET TOTAL)

8
US Operating instructions - digital oval gear meter and pulse meter
5. Total volume multiplication factor (x10/x100)
6. Type of total volume display (TOTAL/RESET TOTAL)
7. Units for total volume; L=litres; GAL=gallons
8. Flow rate display
9. Display of measuring unit for partial volumes:
QTS=quarters; PTS=pints; L=litres; GAL=gallons;
The display can be adapted to the direction of ow in 90° steps. To do so (refer to g. 16-1; item 4),
loosen the four screws . Now you can mount the display unit turned by 90°.
CAUTION
 Take care to ensure that the cables from the battery holder kit (refer to g. 16-1,
item 21) to the board (g. 16-1, item 17) are not pinched or excessively twisted.
Then, re-insert and tighten the screws (refer to g. 16-1, item 4).
3.1.2 User controls
There are two push buttons on the meter (RESET and TOTAL), each controlling two main functions
(pressed individually) and various auxiliary sub-functions (pressed simultaneously).
Main functions:
 RESETT button: Resetting the partial volume register and the (resettable) total volume register
RESET TOTAL.
 TOTAL button: Calling up the calibration mode. Pressed together, the two buttons call up the
conguration mode where you select the unit of measurement.
3.1.3 Measuring chamber
The measuring chamber is located in the centre of the meter.
There is a oval gear in the measuring chamber, set in rotation by the ow of liquid. Each revolution will
generate an electrical pulse that is processed by the microprocessor on the control circuit board.
The microprocessor uses a calibration factor (i.e. a‚weighting‘ assigned to each pulse) to convert the
pulses generated by the gears‘ revolutions into an intelligible value representing the volume of liquid
that has passed through. It is then displayed in the unit pre-set before in the corresponding registers of
the LCD display for partial and total volumes, respectively.
All of our oval gear meters leave the factory with a default calibration factor = 1000 called„FACTORY
K FACTOR“. There is a possibility to calibrate the meter in order to adapt that factor to the physical
properties of dierent liquids.
There is always a possibility to return to the manufacturer‘s default setting.
3.1.4 Battery compartment
The meter is powered by two 1.5 V standard batteries (N1).
The battery compartment is inside the body. To replace the batteries, you must remove the cover.

5. Assembly
The oval gear meter comes pre-assembled and ready to go.
According to the version, accessories may be or must be mounted.
NOTE
Ensure cleanliness during installation and an exact connection and
accurate sealing.
6. Installation
The inlet and outlet of the oval gear meter are aligned in a straight axis and equipped with 1“ threads.
The meter may be installed in any given position, as a xed unit in a pipeline and/or as a mobile unit on a
spigot.
The oval gear meter does not have a pre-dened ow direction. Both ends may alternatively serve as
inlet or outlet, as needed. However, it is absolutely important that the side that is used as inlet (where the
pipeline arrives) is equipped with a lter with suitable performance characteristics. Solid particles getting
into the measuring chamber might clog up the ovar gear.

Operating instructions - digital oval gear meter and pulse meter US
7. Routine operation
The turbine ow meter comes pre-assembled and ready to go.
Even after periods of prolonged storage, it will be ready for operation without any lengthy preparations.
The only action that may be necessary from time to time during normal operation is to reset the registers
of partial and/or resettable total volumes.
To accomplish that, call up the two displays for normal operation. The rst normal operation display
contains the partial volume and resettable total volume (RESET TOTAL). The other display shows the
partial volume and the non-resettable (absolute) TOTAL volume. The LCD automatically switches between
resettable and absolute total in a given period of time. This has been set at the factory and cannot be
inuenced by the user.
RESETTABLE
TOTAL VOLUME
register
ABSOLUTE
VOLUME
register
PARTIAL VOLUME register
The register of the absolute total (TOTAL) cannot be reset by the user. It will continue counting during the
entire lifetime of the meter. The resettable and non-resettable registers of total volumes (RESET TOTAL and
TOTAL) share the same‚window‘ and the same digits of the LCD display. For that reason, the two numbers
cannot be viewed at the same time.
The oval gear meter has been programmed so that the one or the other total is visible at certain moments /
in certain modes during operation (never both at a time):
 The absolute total volume (TOTAL) is visible in standby mode.
 The resettable total (RESET TOTAL) is visible at the following times / in the following modes:
- For a short moment (several seconds) after resetting the (resettable) partial volume.
- During the output of liquid.
A few seconds after output of the liquid this short time span expires and the meter switches to standby
mode. The display of the bottom register shows the absolute total volume.
NOTE
For the display of total volumes, there are 6 digits available, plus two icons x10/x100.
The increments are activated in the following sequence:
0,0 ---> 99999,9 ---> 999999 ---> 100000 x10 ---> 999999 x10 ---> 100000 x100 --->
999999 x100
7.1 Output of liquid during standard operation (Normal Mode)
During standard output of liquid, the meter will count and at the same time display the volume having
gone through the device so far, and the resettable total (RESET TOTAL).
Accidental pressing of the RESET or TOTAL button does not have any eect in this state.

12
US Operating instructions - digital oval gear meter and pulse meter
A few seconds after uid discharge, the display of the lower register will change from resettable total to
absolute total: The word RESET above the word TOTAL will disappear, and the value of the resettable
total will be replaced by the absolute total.
We call this state (or mode)„standby“. It will persist as long as the user does not carry out any more actions
on the meter.
7.1.1 Resetting partial volumes
For resetting the partial volume register: Press the RESET button
while the meter is in standby, i.e. when you see the word TOTAL in
the display.
When you press RESET, the display will rst switch on all the
segments, one after the other, and then switch them all o again.
When the reset is complete, the display will rst show the partial
volume having been reset and then RESET TOTAL.
After a couple of seconds, RESET TOTAL will be replaced by the
NON-resettable total amount TOTAL.
7.1.2 Resetting the resettable total volume RESET TOTAL
You can reset the resettable total only if you have reset the
register of the partial volumes before. To reset the resettable total:
press RESET for several seconds. The display will show the words
RESET TOTAL (see g.):
You must carry out the following steps (in this order):
1. Wait until the display is back to default standby mode
(i.e. showing only TOTAL).
2. Press RESET shortly.
3. The meter will now start resetting the partial volume register.
4. While the display shows RESET TOTAL, press RESET again for at
least one second.

13
Operating instructions - digital oval gear meter and pulse meter US
5. The display will show all the segments again. Only then follows
the phase where all segments are switched o. Finally, there
will be a display showing the total that has been reset (RESET
TOTAL).
7.2 Output of liquid with display of current ow rate (Flow Rate Mode)
It is possible to output a liquid and have the following displays available at the same time:
 Partial volumes having been output
 Current ow rate (Flow Rate) in [unit of partial volume per min.], as shown below.
This is how you get into this mode:
 Wait until the meter is in default standby mode (i.e. the display shows only the total volume).
 Press TOTAL shortly.
 Start output operation.
The display of the current ow rate will be updated every 0.7 secs. For that reason the display may‚utter‘
somewhat with low ow rates. However, the higher the ow rate, the more stable the display will be.
NOTE
The current ow rate will be shown in the unit set for the partial volume register.
That means if partial and total volume have been set to dierent units (as shown in
the example below) you must bear in mind that the ow rate shown is in the unit
set for partial volumes. In the example shown, the ow rate is in QTS./min.
The word GAL next to the ow rate refers to the register of the (resettable and NON-resettable) total
volumes which will be displayed again as soon as you leave the ‚current ow rate‘ display mode.
In order to go back to the default standby mode, press the TOTAL button again.
Accidental pressing of the RESET or TOTAL button does not have any eect in this state.
NOTE
RESET TOTAL and absolute total (TOTAL) are not shown in this mode.
However, the values nevertheless go up. You can check after uid discharge.
Wait for the default standby mode and press TOTAL shortly.
7.2.1 Resetting partial volumes
In order to reset the partial volume register, you must rst complete the output of liquid. Wait until the
display shows a ow rate of 0.0 (see g.) and then press RESET shortly.

14
US Operating instructions - digital oval gear meter and pulse meter
The eect is dierent from what you would have if you press Reset in default standby mode. There is no
phase where all the segments are rst switched on and then o again. Instead, the register will display the
reset partial volume immediately.
8. Calibration
8.1 Denition
Calibration factor or„K FACTOR“:
This is the multiplication factor the system ascribes to the electronic pulses it receives in order to convert
them into a plain unit of measurement.
 FACTORY K FACTOR: Calibration (default) factor pre-set at the factory. Factory K Factor = 1000.
This calibration factor ensures maximum precision under the following operating conditions:
Fluid Diesel DEF
Temperature 20 °C 20 °C
Flow rate 2-60 l/min 5- 30 l/min
You can always return to the original Factory K Factor even after you have changed the value. The
procedure is simple.
 USER K FACTOR: This is the calibration factor the user has set to adapt the meter to specic
requirements (i.e. the user has carried out a calibration procedure).
8.2 Why calibrate?
The oval gear meter comes to you with a calibration factor pre-set at the factory that will guarantee the
most precise measurements under most operating conditions.
If calibration is necessary, it should be conducted under the operating conditions in which the meter is
used, such as in the following extreme conditions:
 liquids having a viscosity close to the admissible limits (e.g. antifreeze with low viscosity, high-viscosity
oils for gearboxes)
 extreme ow rates (i.e. close to upper or lower limits)
8.3 Calibration mode
The oval gear meter has a fast and precise electronic calibration mode where you simply change the
calibration factor (K FACTOR).
There are two calibration procedures you may choose from:
 Calibration during simulated operation (requiring actual output of liquid to be carried out).
 Direct calibration (simply changing the calibration factor).
You may want to call up the calibration procedure for the following reasons (press the TOTAL button for
several seconds):
 To display the valid calibration factor
 To reset the calibration factor pre-set at the factory (FACTORY K FACTOR) after calibration by the user
 To change the calibration factor using one of the two available calibration procedures

15
Operating instructions - digital oval gear meter and pulse meter US
During calibration, the registers on the LCD display - that normally show partial and total volumes of liquid
output - will take on new meanings.
During calibration, the meter cannot carry out normal output operation.
During calibration, the count of the absolute total volume of liquid having been output (non-resettable
total) will not increase.
NOTE
The oval gear meter is equipped with a non-volatile memory so that saved
calibration data and the total output amount will be stored for prolonged periods
of time - even without power supply. That means you don‘t have to re-calibrate
after you have exchanged the batteries.
8.3.1 Displaying the valid calibration factor - resetting the factory calibration factor (if necessary)
Go to default standby mode. Press the TOTAL button. The display shows the valid calibration factor.
Two situations are possible:
a) User never changed the calibration factor and/or user restored the factory calibration factor after
changing it: the display will show the following:
The word FACT (short for FACTORY) indicates that the valid calibration factor is the factor pre-set at the
factory.
b) If calibrations have been made by the user, the calibration value currently used is indicated
(in our example 0,998).
The word USER indicates that the calibration factor currently used was entered by the user.
The ow chart below shows the schematics of the display modes the LCD display may go through.
In this mode, the user may press RESET and thus change from the USER to the FACTORY FACTOR.
In order to conrm your choice, shortly press TOTAL while the display shows either USER or FACT.
After re-start, the meter will use the new calibration factor you just conrmed.

8.3.2 Calibration during simulated operation
This procedure is basically a simulated output of liquid into a calibration vessel under actual operating
conditions (ow, rate, viscosity etc.). The procedure must be carried out with utmost care.
NOTE
Absolutely bear in mind the following points in order to guarantee proper calibration:
 Have your equipment properly vented before calibration.
 Use a calibrated vessel holding at least 5 litres with a precise full mark.
 For calibration, tap a certain amount of test liquid with a constant ow rate,
exactly as you would do in normal operation. Continue until the vessel is full.
 Do not decrease the ow rate when you approach the full mark. Instead, turn
the spigot on and o and ll the vessel in small batches, but make sure the ow
rate remains unchanged.
 When you are nished be sure to wait a few minutes and let air bubbles escape
that may still be in the calibration vessel. Otherwise there is a danger you get a
wrong value because the level in the vessel may still go down.
 Be sure to carry out the following procedure correctly.
8.3.3 Meter calibration during simulated operation

For calibration you must correct the count indicated by
the partial volume register (ex.: 9,800), entering the actual
value, i.e. the volume of the cal vessel. An arrow at the
bottom left of the display (pointing up or down) indicates
the direction in which USER K FACTOR is changed. Increase
or decrease when actions 6 or 7 are carried out.
6 PRESS RESET SHORTLY
Direction of arrow ips. This may be repeated as often as
necessary.
7 PRESS TOTAL SHORTLY / SEVERAL SECS
Value indicated will change as indicated by arrow
 One increment per each time TOTAL is pressed.
 Continuous if the TOTAL button is held down, the rst 5
increments slow, then fast.
 If you overshoot, go back to point 6 and repeat (6).

8 PRESS RESET SEVERAL SECS
This is how the meter‚knows‘ that calibration is now
complete.
Before you press the button, be absolutely sure the
display shows the correct value (volume of vessel).
Actual valueSet value
The meter will now calculate the new USER K FACTOR: This
may take a couple of secs. depending on the complexity of
the correction. The arrow will disappear during this phase,
but the word TOTAL will remain unchanged.
If you carry out this action right after point 5 the new USER
K FACTOR will be equal to the FACTORY K FACTOR. It will be
ignored, therefore.
9 NO OPERATION
After completion of the calculation the new USER K
FACTOR will be displayed a few seconds. Next, the meter
will re-start. Finally, the meter will be back in default
standby mode.
PLEASE NOTE: From now on, the new value set will be
used as the new valid K Factor and will remain even after
replacement of batteries!
10 NO OPERATION
The meter stores the new K Factor for operation and is now
ready for operation using the newly set USER K FACTOR.

8.3.4 Changing the K FACTOR directly
This procedure is helpful for the correction of a mean error that may occur as a result of many output
operations. In the event you observe a mean percentage error during normal meter operation you may
carry out a correction by changing the valid User K Factor by that percentage. In order to calculate the
correction of the USER K FACTOR, proceed as follows:
New calibration factor = old calibration factor x
Example:
Observed mean percentage error E% -0,9 %
Current K Factor 1.000
New USER K FACTOR 1.000 x 100-(-0,9)÷100=
1.000 x (100+0,9)÷100=
1.009
If the meter displays less than the actual amount of liquid output (negative error), the new K Factor must
be greater than the old one (see example). The opposite is true if the value indicated is greater than the
actual amount (positive error).
Operation Display conguration
1 NONE
Meter is in default standby mode, not counting.
2 PRESS RESET SEVERAL SECS
Meter changes to calibration mode displaying the valid K
Factor instead of the partial volume. FACT or USER indicates
whether valid calibration factor is Factory K Factor or User
K Factor.
3 PRESS RESET SEVERAL SECS
Meter shows TOTAL display and the resettable total register
displays zeroes. Meter is now ready for simulated operation
calibration.
4 PRESS RESET SEVERAL SECS
Changing valid K Factor directly: The word DIRECT is dis-
played, together with the calibration factor currently in use.
An arrow at the bottom left of the display (pointing up or
down) indicates the direction in which the displayed value
is changed. Increase or decrease when actions 5 or 6 are
carried out.
5 PRESS RESET SHORTLY
Direction of arrow ips. This may be repeated as often as
necessary in order to set the correct direction.
