INTRODUCTION
1 PRODUCT DESCRIPTION
DigiWolf is a battery powered paddle flowmeter capable of measuring the rate of a fluid in a hydraulic circuit, and it can display the results of these measurements.
1.1Intended 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 flowmeter must not be used to measure the passage of hydrocarbons, flammable, explosive or toxic liquids. The flowmeter is not suitable for contact with liquids for human consumption.
2 Flowmeter ASSEMBLY
Install the flowmeter at least 20 cm from the elements that could cause turbulence inside the tubes (valves, bends, constrictions, etc.). The flowmeter can be installed in a vertical or horizontal position.
CAUTION:
-Do not install the flowmeter with the connector facing downwards (Fig. 1).
-The system must have a filtering element with a filter of at least 50 mesh, together with a safety valve to limit use pressure at the specified max. valve (Tab. 2 - Par. 2.3.1).

Fig. 1
Assemble the flowmeter using the suitable mounting parts (Fig. 2): fit the bolts (M8) in their seats, then make them slide to their stop position to prevent them from coming out.
The flowmeter body must be assembled with the arrow on the label facing the flow direction.

INSTALLATION
2.1Monitor 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).
Fig. 3
1) Remove the fork from the monitor using a screwdriver. 2) Remove the monitor from the flowmeter body.
Fig. 4
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).
Fig. 5
With the aid of a screwdriver, loosen the screw locking the sensor without removing it.
Fig. 6
Rotate the sensor anti-clockwise until reaching B stop position.
Tighten back the screw without forcing it. The monitor is ready to be fitted in perpendicular position to the body.
Fit the monitor back on the flowmeter body.

2.3Hydraulic connections
2.3.1Hydraulic 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 flowmeter (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 flowmeter is going to be installed in.
After connection, check for the perfect sealing of the tubes and fork connections.

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 refit 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.
