case of sale or change of ownership. Keep it for future reference; ARAG reserves the right to modify the
specications and instructions regarding the product at any time and without prior notice.
1 PRODUCT DESCRIPTION
The Orion 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 trough
it; Orion displays 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 (Electro-
magnetic 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.

2.1 Electric connections
The Orion owmeter 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 automatically rendered null and void.
The connections of the Orion owmeter on devices not provided by ARAG are indicated in tables
1a and 1b.
There are two different types of owmeter connectors:

2.2 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.

2.2.1 Hydraulic connections for control units
Flowmeters with mounting ange 463/473 must be installed to specic control units
(Ref. to ARAG General catalogue).
If you need to install the owmeter to an existing control unit that had no owmeter,
consider that you shall order some new linkages to allow for assembly recomposition after installation of the owmeter (Ref. to ARAG General catalogue, Control units
section, Assembly Kit).
CAUTION: BEFORE ASSEMBLING THE FLOWMETER TO AN EXISTING UNIT, MAKE
SURE THAT THE OPERATING PRESSURE IS SUITABLE FOR THE CONTROL UNIT.
ARAG shall not be held liable for any and all damage to equipment, persons, animals
or things arising out of the failure to abide by the above instructions.
Remember to duly position any seals and O-Rings in their seats on anged couplings.
Note: in the control units with standard conguration, the owmeter is usually assembled between the control valve and the section valves unit. This does not mean
that the owmeter can not be installed at any other position; just consider that if
installed in different positions, the owmeter will read different values according to
the connected components.
It is recommended to lter the uid.
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.

3 PRELIMINARY SETUP FOR USE
Set owmeter constant on the computer connected to Orion owmeter: refer to the label on the body
(A, Fig. 6) and tables 5-6a-6b - Chap. 6 "Technical data".
For further information regarding how to set the constant, consult the use and maintenance
manual of the computer being used.
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.
Orion owmeter can only detect conductive uids with a conductivity equal to 300 µS/cm
or higher (Ref. Tab. 3 - Chap. 6).
- 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.

5 MAINTENANCE
- After every spraying operation, ush the pipe with clean water.
- In case of malfunction, and at any rate at the end of every season, clean the owmeter pipe with
a special detergent.
- Do not use metal or abrasive objects for cleaning the duct.
- Do not use solvents or petrol for cleaning the external parts of the device.
5.1 Troubleshooting
FAULT CAUSE REMEDY
The owmeter does not read any
value
The value read by the owmeter is
not linear or stable
No power supply • Check the owmeter wiring.
Presence of turbulence or air in the
circuit
• Check the circuit.
