1. Introduction
The In line meter 24720 is used to measure the volume of fluid filled in an object. The meter is based on the “oval-gear”
Principe. It uses permanent magnets and REED-switches as signal pickup.
The integrated valve is pressure balanced to enable a smooth flow control almost independent of fluid pressure.
It is manufactured with small tolerances to assure a high degree of accuracy over a wide range of flow and viscosity.
To conserve battery the meter goes into sleep mode after 1 minute of inactivity. All data is stored so if it is waken up again it
continues from where it was.
2. Mechanical installation
The meter is delivered in an environmental adapted paper box. The inlet and outlet of the meter is male G1/2 with inside 60°
cone to fit standard hydraulic 60° cone adapters. Use liquid sealant if additional sealant is needed.
Note! –Do not use Teflon tape or other solid thread sealants and do not use excessive torque for the
fittings!
3. Batteries
2 pieces of AAA 1,5 V batteries are used as power source. They are placed in a battery holder. To get access to the battery
holder, loosen the screw on the front of the meter.
4. How to use
Always read the manual before using the meter.
4.1. Check before use
The meter will probably be in sleep mode when you grab it so press the RESET or SELECT button
to wake it up. Then the display should look like this.
4.2. Dispense fluid
To dispense fluid press the <RESET> or <SELECT> button to wake the meter up if it is in sleep mode or just continue the
last dispense. If a new dispense is to be started press <RESET> button after wake up to zero the meter.

4.3. “Trip” counter
The meter is equipped with a “Tripp” counter that shows the accumulated volume of fluid dispensed since it was last
“RESET”. The “Trip” counter can be zeroed, “re-set”.
4.3.1. Check the “Trip” counter
When the meter is in normal dispense mot the TRIP-counter can be shown by pressing the <Select> button.
Normal dispense mode.
Press <SELECT>. May need to be pressed more than once depending on
mode. The total volume (in whole units) since the last re-set is shown.
4.3.2. Reset the “Trip” counter
When the meter is showing the TRIP-counter it could be se-set. This only re-sets the TRIP-counter nothing else.
Press <SELECT>. May need to be pressed more than once depending on
mode. The total volume (in whole units) since the last re-set is shown.
Press <RESET> to zero the TRIP-counter.
4.4. “Total” counter
The meter is equipped with a “Total” counter that shows the accumulated volume of fluid dispensed since the meter was put
into use. The “Total” counter cannot be zeroed (RESET)
4.4.1. Check the “Total” counter
When the meter is in normal dispense mode the TOTAL-counter can be shown by pressing the <Select> button.
Normal dispense mode.
Press <SELECT>. May need to be pressed more than once depending on
mode. The total volume (in whole units) since the last re-set is shown.
4.4.2. Reset the “Total” counter
The “Total” counter cannot be re-set to zero.

5. Calibration
Normally the meter does not need calibration if it is used for normal workshop oils but if fluids with high or low viscosities
or high or low flows are used calibration may be needed.
Also calibration may be needed after a long time of use especially if dirt is present in the fluid.
To make a usable calibration some rules has to be followed.
1. The calibration works for any volume but recommended is at least 1 L.
2. The measuring vessel must be of laboratory grade and absolutely empty. A prior
dispense can easily leave 0.1L or more even if it appears empty. Put the vessel upside down for a while or clean it
before each calibration dispense.
A really accurate calibration can only be made by a scale and knowing the density of the fluid.
3. When a dispense is done all air has to be removed from the fluid. This can take a long time. It can be accelerated by
vacuum. If a scale is used the air does not matter.
5.1.1. Calibration possibility
The meter can be calibrated +/- 10%. If this is not enough the meter chamber should be replaced.
If the calibration factor exceeds this during calibration the display will show an error message “E3” for a while.
Because of that this meter normally gives an accuracy of +/- 0,5% directly from stock for normal workshop oils and
has proved to maintain the accuracy after several 100000 of litres the most probable causes for this error is
Bad measuring vessel.
Measuring vessel not empty from the beginning.
Air in the oil not evacuated properly.
Wrong measured volume input.
5.1.2. Calibration procedure
The calibration process is semiautomatic and started by entering configuration mode.
Press <RESET> and <SELECT> buttons simultaneous
and hold them down for 5 s. If successfully done the
display will change to this, showing that the meter is in
configuration mode. Now release the buttons.
Then press <SELECT> button to get into “Set unit”
mode. The display will change to.
Then press <SELECT> button again to get into
“Calibration” mode. The display will change to.
Then press <RESET> button to start the calibration
process. The display start switching between “dISP” and
“0.0000”.
◄▬ ►
Now start dispensing. It does not matter how much you
dispense but to get a good calibration at least 1L is
recommended. During the dispense it will switch
between “dISP” and the dispensed volume.
◄▬ ►
When the decided volume is reached, in this case
1.5639L, release the handle of the meter so the flow
stops.
◄▬ ►

Then press <SELECT> and the display will move on to
received volume input. The first figure will “blink” to
show that it is changeable. Press <RESET> to change
the value press <SELECT> to change to the next figure.
◄▬ ►
In this example we received 1.6852 L so we move to
second figure with <SELECT> and change it from 5 to
6 with <RESET> move to third figure and change it
from 6 to 8 and so on.
◄▬ ►
When the last figure is blinking and <SELECT> is
pressed the display will change to show the calculated
calibration factor. If <RESET> is pressed the new
calibration is cancelled.
If <SELECT> is pressed the calibration is saved and
then the meter goes back to normal dispense mode. The
calibration is done.
▬ ►
If the calculated factor exceeds +/- 10% the error
message “E3” will be shown for a while and then it will
go back for a new calibration dispense.

5.2. Unit used for measuring
The meter can be set to use either [L]itre, [G]allon, [P]int or [Q]uater. The unit used is shown after the value.
5.2.1. How to set the unit
Press <RESET> and <SELECT> buttons simultaneous
and hold them down for 5 s. If successfully done the
display will change to this, showing that the meter is in
configuration mode. Now release the buttons.
Press <SELECT> button to get into “Set unit” mode. The
display will change to.
Scroll through the different units using the <RESET>
button. L, G, P, Q, L,…… . When the wanted unit is
shown release all buttons and wait. The will save and go
back to “ConF” after a short time.
WAIT!
To get back to normal operation mode wait a short time
or press <RESET> button. When the display looks like
this it is done.

5.3. LCD segment test
The LCD can be checked by putting the meter in normal dispense mode.
Normal dispense mode.
Press <RESET> and the meter will do a re-set and
show all the segments of the LCD for a short while.
5.4. Battery status
The status of the batteries is shown on the display.
Batteries OK.
Batteries LOW, needs to be replaced. Replace with 2
pieces of 1,5 IEC LR03 / ANSI AAA batteries. Be
sure to put the new ones in the correct direction!
