Table 27: Option I/O errors description
Error Code Error Message Description
A24:Aout(S2:1)OutOfRa nge!
When output from analog output(S2:1)
exceeds 21 mA or less than 3.6 mA
Check the flow velocity. If velocity is
within limits and error still persists,
contact Panametrics factory
A25:Aout(S2:2)OutOfRa nge!
When output from analog output(S2:2)
exceeds 21 mA or less than 3.6 mA
Check the flow velocity. If velocity is
within limits and error still persists,
contact Panametrics factory
A31:(S2:3)Ch UnderRange!
Lesser input values. For analog
input(S2:3) between 3.6 mA to 0.25mA
Check input analog current is between
3.6 mA to 21mA. If error persists, contact
Panametrics factory
A32:(S2:4)Ch UnderRange!
Lesser input values. For analog
input(S2:4) between 3.6 mA to 0.25mA.
Check input analog current is between
3.6 mA to 21mA. If error persists, contact
Panametrics factory
4.11 Diagnostics data
To determine the health of the meter, PanaFlow™ LC has built-in diagnostic parameters. Please refer to Table 28 below for
diagnosing any problems with the system. If the meter shows errors and the diagnostics data indicate issues, fill in the User/
Service record appendix before contacting Panametrics 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.
