1 PRODUCT DESCRIPTION
The Orion 2 Visual Flow 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 2 Visual Flow displays the owrate calculated according to the data received from the owmeter
and the value of the owmeter constant previously set.
Furthermore Orion 2 Visual Flow can be used as a lling owmeter; this function enables the setting of the quantity of liquid with which the tank is to
be lled during loading and by using the Pump Stop Kit (optional) enables loading to be stopped when the set value has been reached.
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 2014/30/UE 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

3 PRELIMINARY SETUP FOR USE
3.1 Access to "COST" setup menu
The right "constant" needs to be programmed in order to visualize the data on the display correctly.
WARNING: this data has already been entered in the production phase.
If the value measured by the owmeter is different from the actual sprayed value, the precise constant that needs
to be entered can be calculated by using the following formula:
[quantity measured by the device] x [constant indicated on the owmeter body]
[actual sprayed quantity]
Therefore, when the constant that is either calculated or shown on the label applied to the side of the owmeter
(g. 5) needs to be veried or calculated, access the "COST" menu by holding down the [RESET] button during
startup until the "COST" page is displayed:
• Flowmeter constant (1 ÷ 29999 - EU: cm/imp - US:inch/imp)
3.2 Setting the ow-meter constant
1) After having been turned ON, as shown in par. 3.1, the display alternately ashes the currently set value of the ow-meter constant and
the word "COST".
2) To modify the value, keep the keys pressed simultaneously until the "SET" screen appears.
3) Set the ow-meter constant using the [TOT] key to increase it and the [RESET] key to decrease it; keep the keys pressed to enable
quick-modication.
4) To conrm the setting, keep the keys pressed simultaneously until the "SAVE" screen appears.
The display alternately ashes the currently set ow-meter constant and the "COST" screen.
The display shows values greater than 9999 (pls/l - pls/gal) with the aid of graphic elements on the display as shown below:
When symbol " "is displayed, the constant value is to be
calculated as follows:
Constant = Displayed value + 10000
e.g.
2500 + 10000 = 12500
When symbol " " is displayed, the constant value is to be
calculated as follows:
Constant = Displayed value + 20000
e.g.
2500 + 20000 = 22500
3.3 Notes on programming
After having modied a parameter in the "OPT" Advanced menu, to return to the Main menu turn the device off and then on again.
When you are modifying a parameter or are in a Menu other than the Main menu and you do not press a key within 10 seconds, the display will
automatically return to the Main menu.
When modifying a numerical value, keep the key pressed to enable quick modication.

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. 6):
LED OFF:
the device is not powered.
LED ON NOT FLASHING with low light intensity:
the device is powered but it does not detect liquid passage.
LED ON FLASHING with high light intensity:
the device is powered and it detects liquid passage.
La frequenza dell'intermittenza è proporzionale alla portata.
Orion 2 Visual Flow owmeter can only detect conductive uids with a conductivity equal to 50 μS/cm (Ref. Tab. 4 - Par. 5.2).
- 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.
