"pulse value"
Use this parameter to specify the flow volume after which a pulse is generated.
Default: 100 m
3
"pulse width"
Use this parameter to specify the width of each pulse.
Default:
• HART: 200 ms
• Profibus DP: 1000 ms
Range of values:
• 200 to 60000 ms
!
Note!
If a relay is used in a Profibus DP instrument to transmit the pulses, the pulse width can be reduced.
If the DI block is used, 1000 ms is the smallest possible value.
5.1.6 "relay N " (N = 1 - 6)
(Display of the counting value)
"pulse counter"
Displays the number of pulses which have been generated since the last overflow.
"overflow"
Displays, how many times the pulse counter has already passed the overflow.
!
Note!
The total flow volume is:
V
total
= (overflow x 10

+ pulse counter) x pulse value
"reset counter"
Use this parameter to reset the counter.
Selection:
• no (default)
"pulse counter" and "overflow" retain their values.
• yes
"pulse counter" and "overflow" are reset to "0".
