Basic Flow measurement WARNING
This warning occurs if 1…4 paths fail, but the system works within specifications.
Possible sources of the warning are over range, path failure, deviation in sound velocity or
communication failure.
Basic Flow measurement ERROR
This error occurs if all paths fail.
Possible sources of the error are over range, path failure, deviation in sound velocity, communication
failure
System Runtime WARNING
This warning is caused by system failures or failures from the Modbus driver. See system messages
These failures will not influence the flow measurement.
The last warning number is saved into the integer and long integer field System Runtime warning/error
number…
System Runtime ERROR
This error is caused by system failures. See system messages
These failures might influence the flow measurement.
The last error number is saved into the integer and long integer field System Runtime warning/error
number.
System Set-up WARNING
This error is caused by insufficient statistical data during set-up. Default data is used until enough
statistical information is recorded (under normal conditions).
In this case the warning is self-resolving.
Another possibility is an improper initialisation of the Modbus driver (Modbus will not be accessible). In
this case, the warning remains active.
The integer and long integer System Set-up warning/error number contains the error number.
See the Altosonic-V Operating Manual
System Set-up ERROR
This error is caused by an improper initialisation. The Modbus driver may be initialised successfully.
The integer and long integer System Set-up warning/error number contains the error number.
See the Altosonic-V Operating Manual
Resetable totaliser Rollover occurred
Status for if the totaliser exceeds the value of 1
E 9 liter, the totaliser is decreased with 1 E 9 and the
totaliser Rollover occurred Boolean is set.
Resetable totaliser Reset occurred
Status for if the totaliser has been reset (by Modbus, manually, or relay contact).
Flow direction
Status for the current flow direction: 0=forward direction, and 1=reverse direction.
Algo. Basic flow on output
Status for calculation with the basic algorithm.
Algo. Reyn. Correction on output
Status for calculation with the basic algorithm, including Reynolds correction algorithm.
Swirl correction on output
Status for calculation with the basic algorithm, including Swirl correction algorithm.
Temperature correction on output
Status for correction for tube expansion caused by temperature deviation.
