Electric connections
The Orion 2 flowmeter 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 flowmeters of this typology.
ARAG is not liable for damage to the system, persons, animals or things caused by incorrect or inadequate installation of the
flowmeter. In the event of damage to the flowmeter, caused by incorrect or unsuitable assembly, any form of guarantee is auto-
matically rendered null and void.

Hydraulic connections
For connection to the system, use appropriate fittings (Ref. ARAG General catalogue).
Avoid bends and constrictions before connections and on tubes.
Regarding connections, use tubes and fittings 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 fittings 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 flowmeter is going to be installed in.
