Actual Flow
Unit: m3/h - it is not possible to change it.
Real value = Actual value / 1000.
Flow Sign
Sign of the read flow.
0
– positive flow
1
– negative flow
Total (Total +, Total -, Aux +)
Unit: m
3
– it is not possible to change it.
The final number is given by the sum of the whole and the decimal.
Example: Resulting Total measurement = (TOTAL DIG) + (TOTAL DEC*10^-3).
Error Code
Convert read value to binary code. For more information see chapter 10.
Data from AD converter
Raw data from AD converter. This data are averaging in average data from AD converter register.
Average data from AD converter
Average raw data from AD converter. This data are used for flow calculating according to calibration curve.
Empty pipe data from AD converter
Raw data from AD converter. This data are used for detection of empty pipe alarm. Threshold for detection
is possible to setup in Air constant register.
Temperature
Real value = Actual value divided by 10.
Unit: °C – it is not possible to change it.
If value of any volume counter is higher than 999 999 999 m3, then this volume will be reset
to 0.
