2.3 Hydraulic connections
2.3.1 Hydraulic connection for brass/fork connections
Avoid bends and constrictions before connections and on tubes.
Use ARAG connections with their suitable OR with MALE CONNECTIONS [T connections - General Catalogue (Tab. 2)].
The tubes must be able to stand a pressure of at least twice the max. operation pressure of the owmeter (Tab. 2)
CONSIDERING THE OPERATION PRESSURES WITHIN THE SYSTEM.
Hose tail tightening must be done using the suitable metal clamps to ensure perfect mechanical sealing, even at high pressures.
The connection with threaded connectors must be done paying attention to operation pressure.
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.
After connection, check for the perfect sealing of the tubes and fork connections.
