data indicate issues, fill in the User/Service record appendix before contacting BHGE factory.
Table 28: Diagnostic Parameter Description and Health Indicators
Parameter Description Good Bad
Sound Speed Measured speed of
sound of the fluid
• Under ideal conditions
sound speed should be
within 5 ft/s (1.5 m/s)
between channels.
• Depending on flow
viscosity, flow rate,
there can be slightly
different sound speed
showing on different
channels. This could
be normal due to
different signal path.
• Under ideal conditions, sound
speed spread of 30 ft/s (9 m/s)
or more between the sound
speed measurement of the
channels can be an indication
of a problem with the pipe
installation or any other
different local pipe condition.
SNR Up Signal to noise ratio
of the upstream
transducer
>5 <2
SNR value between 2 and 5 shall
provide valid measurements but
can be an indication of a problem
with the pipe installation or any
other different local pipe condition.
Verify the clamping fixture
alignment, transducer spacing,
transducers, couplant, all the other
connections.
SNR Down Signal to noise ratio
of the downstream
transducer
>5 <2
SNR value between 2 and 5 shall
provide valid measurements but
can be an indication of a problem
with the pipe installation or any
other different local pipe condition.
Verify the clamping fixture
alignment, transducer spacing,
transducers, couplant, all the other
connections.
