1 PRODUCT DESCRIPTION
The Orion 2 electromagnetic owmeter is a device that enables measurement of the quantity of liquid passing through it.
Using a principle of electromagnetic measurement (there are no moving mechanical parts inside it), the owmeter outputs a signal to the computer
proportional to the liquid ow that goes through it; Orion 2displays the owrate calculated according to the data received from the owmeter and the
value of the owmeter constant previously set.
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. Use for sales transactions is not allowed.
2 INSTALLATION
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 horizontal or vertical position.
CAUTION:
For proper sealing of the owmeter, use ARAG assembly kit ONLY (Ref. ARAG General catalogue - Accessories for series 463/473
modular valves).
ARAG is not liable for damage to the system, persons, animals or things caused by the use of material other than specied.

2.2 Assembly
To ensure trouble-free operation, comply with the indicated installation layout (Fig. 5a and Fig. 5b).
The connector must NEVER be positioned upwards.
OK
OK
- Comply with the correct uid inlet-outlet direction, as indicated by the arrow printed on the owmeter body (Fig. 6).
INOUT IN OUT
Use inlet and outlet pipes of the same diameter as the internal passages of the owmeter; for any reference, see tables 7a-7b-7c
(Chap. 5 - Technical data).

2.3 Electric connections
The Orion 2owmeter has been designed to be connected to ARAG devices (computers, screens, displays) but can also be connected to equipment
made by other manufacturers as long as they are designed for owmeters of this typology.
ARAG is not liable for damage to the system, persons, animals or things caused by incorrect or inadequate installation of the
owmeter. In the event of damage to the owmeter, caused by incorrect or unsuitable assembly, any form of guarantee is auto-
matically rendered null and void.

2.4 Hydraulic connections
For connection to the system, use appropriate ttings (Ref. ARAG General catalogue).
Avoid bends and constrictions before connections and on tubes.
Regarding connections, use tubes and ttings properly sized for the operating pressure of the system.
The tightening of hose tails should be made with special metal clamps ensuring perfect sealing even at high pressures.
The connection by means of threaded ttings should be done taking operating pressure into account.
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.

2.5 Hydraulic connections for control units
The Orion 2 owmeters to be integrated in the control units are available with both anged 863/873 (in previous 463/473 series) and T5 fork coupling
connectors.
If you need to integrate the owmeter in an existing tie rod control unit previously congured without a owmeter, remember to order new tie-rods
in order to reconstruct the unit correctly after the owmeter has been incorporated (Ref. ARAG general catalog, control unit section, assembly kit).
ONLY use ARAG tie-rods. If other tie-rods are used, the warranty is automatically void.
Flowmeters with fork coupling do not need other accessories and can be directly inserted in the existing control unit provided it already comes with
T5 fork coupling.
CAUTION: BEFORE INCORPORATING THE FLOWMETER TO AN EXISTING CONTROL UNIT, MAKE SURE THAT THE OPERATING
PRESSURE IS SUITED FOR THAT SPECIFIC CONTROL UNIT.
FLOWMETERS WITH T5 FORK COUPLING CAN WITHSTAND A MAXIMUM PRESSURE OF 20 BAR.
ARAG is not liable for damages to the equipment, persons, animals or objects caused by failure to observe the above instructions.
Remember to correctly position seals and O-Rings in the coupling seats.
Note: usually, in standard control units, the owmeter is inserted between the control valve and the section valves unit (Fig. 8a-8b).
This does not prevent the assembly of the owmeter in any other part of the control unit, however, keep in mind that if the owmeter is positioned in
different points the values may differ depending on the connected components.
Filtering the liquid is recommended.
In order to obtain a correct reading, contact a dealer or installer that can give you advice on how to correctly position the
owmeter inside the control unit.

4 USE
When using the system, the owmeter sends impulses to the computer, which, according to the constant value previously set, indicates the instant ow.
A LED in the connector slot indicates the status of the device (Fig. 10):
Orion 2 owmeter can only detect conductive uids with a conductivity equal to 50 μS/cm (Rif. Tab. 5.2 - Chap. 5).
- Do not aim pressurised water onto the equipment.
- Respect the device’s rated power requirement (12 Vdc).
- If arc welding is required, ensure that owmeter power is off and disconnect the power cables, if necessary.
- Use the owmeter only within the ow limits given in the “Technical data” table. Outside these limits, the owmeter could give incorrect
data and therefore lead the operator or the automatic system to make errors.
ARAG cannot be held responsible for damage caused to persons, animals or things by incorrect or unsuitable use of the owmeter or its parts.
