Assessment of installation position
Type of fluid
Position
Assessment
Pure liquids
Standard installation
position
Self-draining flow tubes
Position A or B
OK
Position C
Liquid residue remains in pipe
Liquids with gas bub-
bles
Standard installation
position
Self-draining flow tubes, gas bubbles do not accumulate
in flowmeter
Position A
Not recommended owing to gas bubble accumulation in
flowmeter
Position B
Gas bubbles may accumulate in the presence of low flow
velocities
Position C
No gas bubble accumulation in flowmeter, liquid residues
may remain in device after discharge
Liquids containing
substances that could
form deposits
Standard installation
position
Self-draining flow tubes, no deposit formation
Position A
OK
Position B
Substances in the liquid could form deposits at low flow
velocities
Position C
Not recommended owing to presence in flowmeter of
substances that could form deposits
Liquids containing
gas bubbles, as well
as gas bubbles con-
taining substances
that could form de-
posits
Standard installation
position
Self-draining flow tubes, no accumulation of gases or
substances that could form deposits
Position A
Not recommended owing to gas bubble accumulation in
flowmeter
Position B
Gas bubbles or substances that could form deposits at
low flow velocities
Position C
Not recommended owing to presence in flowmeter of
substances that could form deposits
Gases that do not
form a condensate
Standard installation
position,
Position A, B or C
Any of these installations positions can be used
Gas, condensate-
forming gas/liquid,
moisture
Standard installation
position
Flow direction should be from top to bottom so that any
condensate that forms can flow out efficiently
Position A
OK
Position B
Condensate might form in flowmeter
Position C
Not recommended owing to condensate accumulation in
flowmeter
