Status 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). - STS

Corrected pulse
increment Number of good pulses within the
last calculation cycle - CORINC
Corrected frequency Frequency that corresponds to the
last corrected pulse increment the
last calculation cycle Hz CORFRQ
Error pulse increment Number of bad pulses within the last
calculation cycle ERRINC
Error pulse rate Number of bad pulses within the last
calculation cycle divided by the last
calculation cycle time in seconds Hz ERRFRQ
Flow direction 0: Forward
1: Reverse - FLOWDIR
Raw pulse increment
channel A Number of raw pulses of channel A
within the last calculation cycle RAWINCA
Raw pulse increment
channel B Number of raw pulses of channel B
within the last calculation cycle RAWINCB
Missing pulse count
channel A Total missing pulse count channel A
since the last reset - MISCNTA
Added pulse count
channel A Total added pulse count channel A
since the last reset - ADDCNTA
Missing pulse count
channel B Total missing pulse count channel B
since the last reset - MISCNTB
Added pulse count
channel B Total added pulse count channel B
since the last reset - ADDCNTB
Simultaneous pulses Total simultaneous pulse count since
the last reset SIMPLSF
Phase difference 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. - PHASEDIF
