1 PRODUCT DESCRIPTION
The Orion Visual Flow electromagnetic owmeter is a device that permits measuring and reading
on the display the liquid quantity passing through it.
Using a principle of electromagnetic measuring (there are no internal moving mechanical parts)
the owmeter gives a signal in proportion to the ow of the liquid passing through it; Orion displays
the value of the owrate calculated according to the impulses generated and the value of the previously programmed owmeter constant.
Furthermore Orion 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 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 vertical or horizontal 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 Visual Flow owmeter has been designed to work as a separate device or to be connected
to ARAG appliances (computers, screens, displays) or to equipment by other manufacturers as
long as the latter is designed for use with owmeters of this kind.
When used as a lling owmeter, the owmeter should ONLY be connected to ARAG
appliances.
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.
Connections of the owmeter to devices not produced by ARAG are shown in Table 1.

(square wave)
It is possible to connect Orion Visual Flow to computers and screens in the Bravo series without the
"Pump Stop Kit" using the adapting cable (code 4622BA50000.110), which enables the connection
between the 4-pole connector on the owmeter and the 3-pole connector on the Bravo.
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.

3 SWITCH ON
When the owmeter is turned on, after a diagnostic test, it displays the following information in
sequence:
• Software version;
• Unit of measurement;
• Indicator of data displayed.
4 PRELIMINARY SETUP FOR USE
4.1 Notes on programming
After having modied 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 modication.
4.2 "OPT" Advanced menu
Upon installation of the owmeter in the lling system some settings are
needed to properly display the lling data:
• Operation mode
• Unit of measure
• Valve operation time
To access the Advanced menu, keep the key pressed while switching ON
Fig. 6
4.3 "MODE" Operation mode
It is possible to set three different operating modes:
MODE 0 = Tank lling count with pump stop control (0000 ÷ 9999 EU: l [predened setting] - US: Gal).
MODE 1 = Flowrate display.
MODE 2 = Tank lling count with pump stop control (0 ÷ 999,9 EU: l - US: Gal).

4.5 "VAL" Valve operation time
This parameter lets you set the time it takes the valve installed on the system to complete its closing
operation; setting this value the owmeter enables to anticipate the exact moment in which
closing begins, thus avoiding the introduction of a greater amount of product when the set value
is reached.
VAL = 0 ÷ 20 sec.

5 USE
When using the system the owmeter sends pulses to the computer which will indicate instantaneous
owrate based on the constant value previously set.
The owmeter can only detect the passage of conductive liquids having conductivity greater
than or equal to 300 µS/cm (Ref. Table 3, Chap. 7).
- Do not subject the equipment to jets of water under pressure.
- Respect the required power supply voltage (12 Vdc).
- If arc welding is needed, make sure that the power supply to the owmeter is disconnected; if necessary disconnect power cables.
- Use the owmeter only within stated owrate limits (Ref. Table 4, Chap. 7). Outside these
limits, the owmeter may provide incorrect data, thus misleading the operator or the automatic system.
ARAG cannot be held responsible for damage caused to persons, animals or things due to
incorrect or inadequate use of the owmeter or its parts.
5.1 Mode 0 - Mode 2 Use
5.1.1 Displaying data
The following parameters can be displayed during operation:
Total liquid introduced into the tank
Instantaneous rate 0 ÷ 999,9 (EU: l/min - US: Gpm)
5.1.2 Setting the amount of liquid to load into the tank
In this operation mode the owmeter displays the total amount of liquid to load into the tank:
0 ÷ 9999 (EU: l - US: Gal) - "Mode 0"
0 ÷ 999,9 (EU: l - US: Gal) - "Mode 2"

After having been turned on, the display shows the amount of liquid to load into the tank; to modify it,
proceed as follows:
1) Press RESET key until "FILL" screen appears.
2) Set the amount of liquid to load into the tank using TOT key (increase) and RESET key (decrease); keep
the keys pressed to enable quick modication.
3) To conrm the setting, keep the keys pressed simultaneously until "SAVE" screen appears.
4) The set amount of liquid to load into the tank is displayed preceded by "TOT" screen.

liquid loaded into the tank is displayed in real time.
3) Press TOT key to display the instantaneous rate of the liquid loaded into the tank, preceded by "LIT"
screen. Press the key again to display the amount of liquid introduced into the tank.
4) When the set value has been reached, the display alternately ashes "END" screen and the total
amount of liquid loaded into the tank.
If the Pump Stop Module is present, the lling device will automatically stop; otherwise, it should be
stopped manually.
