INTRODUCTION
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 specied max. valve (Tab. 2 - Par. 2.3.1).
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.
OK OK
NO!
Fig. 1
The owmeter body must be assembled with the arrow on the label facing the ow direction.

2.1 Monitor rotation
Fig. 3
INSTALLATION
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.
Fig. 4
Fig. 5
Fig. 6
If the monitor is turned upside down, the letters A and B can 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 B stop position.
Fig. 7
Tighten back the screw without forcing it. The monitor is ready to be tted in perpendicular position to the body.
Fit the monitor back on the owmeter body.

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.

INSTALLATION
2.4 Power supply
DigiWolf is powered by 2 AA batteries type LR6 (alkaline) or FR6 (Li-Fe S2).
2.4.1 Battery replacement
When the batteries are low, the symbol will blink on the display.
Fig. 10
To insert or replace the batteries, proceed as follows:
1) Remove the lid of the battery compartment (A) loosening the 4 screws (B);
2) Remove the battery support (C) and replace the batteries, respecting their polarity (as indicated).
3) Fit the support back in its housing and ret the lid by tightening the 4 screws without forcing them, taking care not to crush or break
the wires in the battery case and that the lid seal remains in its seat.
