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 specied.

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.
