1 PRODUCT DESCRIPTION
DigiWolf is a battery powered paddle owmeter capable of measuring the rate of a uid in a hydraulic circuit, and it can display the results of these
measurements.
1.1 Intended use
This device is designed to work on agricultural machinery for crop spraying applications.
The machine is designed and built in compliance with EN ISO 14982 standard (Electromagnetic compatibility - Forestry and
farming machines), harmonized with 2004/108/EC Directive.
The owmeter must not be used to measure the passage of hydrocarbons, ammable, explosive or toxic liquids. The owmeter
is not suitable for contact with liquids for human consumption.
2 FLOWMETER ASSEMBLY
Install the owmeter at least 20 cm from the elements that could cause turbulence inside the tubes (valves, bends, constrictions, etc.).
The owmeter can be installed in a vertical or horizontal position.
CAUTION:
- Do not install the owmeter with the connector facing downwards (Fig. 1).
- The system must have a ltering element with a lter of at least 50 mesh, together with a safety valve to limit use pressure at
the specied max. valve (Tab. 2 - Par. 2.3.1).
OK NO! OK OK
Assemble the owmeter using the suitable mounting parts (Fig. 2): t the bolts (M8) in their seats, then make them slide to their stop position to prevent
them from coming out.
The owmeter body must be assembled with the arrow on the label facing the ow direction.

2.1 Monitor rotation
In case of vertical assembly, to simplify the use of the DigiWolf it is possible to rotate the
monitor by 90° with respect to the body (Fig. 3).
1) Remove the fork from the monitor using a screwdriver.
2) Remove the monitor from the owmeter body.
If the monitor is turned upside down, the letters Aand Bcan be seen: these correspond to
the two possible monitor positions (parallel and perpendicular to the body).
DigiWolf is supplied with the sensor in position A(parallel to the body).
With the aid of a screwdriver, loosen the screw locking the sensor without removing it.
Rotate the sensor anti-clockwise until reaching Bstop position.
Tighten back the screw without forcing it. The monitor is ready to be tted in perpendicu-
lar position to the body.
Fit the monitor back on the owmeter body.

2.3 Hydraulic connections
2.3.1 Hydraulic connection for brass/fork connections
Avoid bends and constrictions before connections and on tubes.
Use ARAG connections with their suitable OR with MALE CONNECTIONS [T connections - General Catalogue (Tab. 2)].
The tubes must be able to stand a pressure of at least twice the max. operation pressure of the owmeter (Tab. 2)
CONSIDERING THE OPERATION PRESSURES WITHIN THE SYSTEM.
Hose tail tightening must be done using the suitable metal clamps to ensure perfect mechanical sealing, even at high pressures.
The connection with threaded connectors must be done paying attention to operation pressure.
CAUTION: For the implementation on already operating systems it is necessary to follow all safety rules described herein.
System assembly and start-up must be carried out by expert personnel according to the safety rules so as to ensure the same
safety level of the system the owmeter is going to be installed in.
After connection, check for the perfect sealing of the tubes and fork connections.

4 PRELIMINARY SETUP FOR USE
For a correct display of data regarding treatment, some preliminary set ups are necessary when installing DigiWolf on farming machines.
4.1 Calibration
Rate reading may not be correct due to different system congurations (tubes, valve, etc.).Therefore, we recommend to make
a spray test; in case the measured value is different from the real one, perform an automatic calibration procedure or manually
calculate owrate constant.
4.1.1 Automatic calibration
Make a quantity of liquid previously measured or that can be measured with another system go through the owmeter. The greater the amount of
liquid used to perform the calibration procedure, the more accurate the calibration.
End reading
0.0 l/min

2) Access Automatic calibration menu (Setup menu > Calibration > Auto calibra-
tion). Once inside the menu, the device is ready to start measuring without
any further controls.

3) Make the liquid go through the system. The display will start to show the incre-
asing value of the measured quantity of liquid. Once liquid passage has nished,
the value on the display will not change any more.
At this point, press OK. In the lower part of the display, the message Stabi-
lization will come up and the device will show the screen on the side.

Display of liquid amount read by the owmeter during calibration procedure.
4) Using the keys, enter the values of the liquid quantity previously measured:
A) Press to toggle from one digit to another
B) Press in succession to modify the value of the digit highlighted by the cursor
C) Press to complete calibration procedure, or D) Press for 1 sec. to cancel calibration procedure.
If, after starting calibration, the device does not sense any ow passage (and the display remains in 0), press OK to exit the calibration
procedure without saving.
If the device continues to sense the liquid ow after pressing OK, after a few seconds the error message Stop flow!will be displayed.
Once the ow has been interrupted, the reading will stabilize as by standard procedure.

Press ESC for two seconds. The totalizer will zero.
- Do not place DigiWolf under pressurized water.
- Use the owmeter only within recommended rate range (Tab. 2 - Par. 2.3.1). Beyond these limits, the ow-meter may give out incorrect data.
- To avoid damaging the owmeter, do not exceed the maximum rate except for short periods.
ARAG can not be held responsible for damage caused to persons, animals or things from the incorrect or unintended use of Digiwolf or
its parts.
- Do not exceed the max. operation pressure (Tab. 2 - Par. 2.3.1).
Display of the symbol ------ shows that the rate or the totalizer are over the max. displayable value.
Totalizers have oating points and display a max. of 5 gures. Up to 999.99 two decimals are shown, it then drops to 1 and 0 with the tran-
sition to thousands and tens of thousands (Fig. 43).

6 CLEANING AND REPAIR
- At the end of each treatment, run clean water through the tubes.
- If necessary, periodically clean or replace the owmeter paddle (Par. 6.2). Periodically clean the paddle anyway.
Do not use metal or abrasive objects to clean the paddle.
Do not use solvents or fuel to clean the case outer surface.
CAUTION:
Before each of the following operations, use the following precautions:
1) Wear gloves, goggles and protective clothing.
2) Stop the machine and disconnect the power of the system.
3) Make sure that the system is no longer under pressure.
When replacing the sensor or the paddle, check for the correct reading of the owmeter. Proceed to a new calibration if necessary.
6.1 Troubleshooting
FAULT CAUSE REMEDY

5) Immerse the paddle group in detergent liquid for several hours.
6) Wash the paddle group thoroughly with running water and check its correct operation. If necessary, replace the complete paddle group with its
suitable spare part (code 4626000.500).
