8. Mechanical Connection
Mounting position:
any
Flow direction:
flow direction: both directions are possible, preferable flow
D
according to the identification plate.
Minimum pressure:
on the outlet of the volumeter the pressure should be higher
than 0,1 bar. In no case the medium may run out free of the
volumeter
Unclean medium:
filtration with max. 0,3 - 0,5 mm mesh width is required
Foreign substance:
the pipe system must be free from welding beads, scabs a.
s.o., as they can block the volumeter
Over pressure valve:
a blocked volumeter stops the complete flow of the medium,
therefor depending the application, an overpressure valve is
required.
Fastening:
without tensions to prevent distortion of the volumeter pipe
thread connection.
Pipe thread connection: the thread length of the pipe may not be longer than the thread
length of the volumeter (reduction of the flow area resp.
damage of internal parts of flowmeter)
Manometer connections: should be approachable
thread: R 1/4")
Storing:
incorrect storing can cause corrosion even seizing
Attention:
When the volumeter or installations are damaged, medium could flow
out. To prevent consequential damage an appropriate alarm device should be
installed.
