PHASE 2 - TRANSMITTER INSTALLATION

TRANSMITTER MOUNTING

Orient the process flanges to enable process connections to be
made.
It is important to mount the transmitter and to lay the process
piping so that gas bubbles, when measuring liquids, or
condensate when measuring gases, can flow back into the
process.
Vent/drain screw valves on the transmitter can be ordered on
the flange side (near the top or bottom part of the flange) or on
the process axis. The transmitter and these drain/vent valves
have to be located higher than the taps on liquid service in order
to allow the venting of entrapped gas or below the taps on gas
service in order to allow the air or condensate to vent off.
For safety reasons, orient the drain/vent valves so that process
fluid is directed down and away from technicians when the
valves are used. This can be accomplished by pointing the hole
in the outside valve body downward and away.

Traditional (Barrel) Housing horizontal mounting with bracket
for vertical or horizontal pipe (option B1 and B2).
In addition, consider the need for a testing or calibration input,
and provide space for the housing covers to be removed for
electrical wiring and maintenance.
WARNING !
Process leaks may cause harm or result in death.
Install and tighten process connectors and all accessories
(including manifolds) before applying pressure.
In case of toxic or otherwise dangerous process fluid, take
any precautions as recommended in the relevant Material
Safety Data Sheet when draining or venting.
Use only a 12 mm (15/32 ") hexagonal spanner to tighten
the bracket bolts.
