Remark
0: Normal
1: Input argument out of range
2: No A pulses (while B pulses)
3: No B pulses (while A pulses)
4: Missing pulses channel A
5: Missing pulses channel B
6: Added pulses channel A
7: Added pulses channel B
8: Simultaneous pulses
9: Pulse rate error
10: Low frequency (above 0 and
below cut-off)
11: Error pulses
Note: during normal operation status
'Low frequency' occurs for a relative
short time whenever the flow starts
or stops. In order to avoid
unnecessary alarms the
corresponding alarm delay time shall
be defined accordingly (default 5
sec).
Number of good pulses within the
last calculation cycle
Frequency that corresponds to the
last corrected pulse increment the
last calculation cycle
Number of bad pulses within the last
calculation cycle
Number of bad pulses within the last
calculation cycle divided by the last
calculation cycle time in seconds
0: Forward
1: Reverse
Number of raw pulses of channel A
within the last calculation cycle
Number of raw pulses of channel B
within the last calculation cycle
Total missing pulse count channel A
since the last reset
Total added pulse count channel A
since the last reset
Total missing pulse count channel B
since the last reset
Total added pulse count channel B
since the last reset
Total simultaneous pulse count since
the last reset
Last measured phase difference
between A and B pulse expressed as
the ratio of the time delay between
the last A and B and the time
between two A pulses. A typical
phase difference is 90°
corresponding to a value of 0.25.
