Pulse output A and B give the same number of pulses, but pulse output B is shifted half a pulse
width in time. Pulse output B always runs behind pulse output A.
In case of a forward flow, pulse output A and B give the forward volume passing through the
meter.
In case of a reverse flow, pulse output A and B only start to give pulses again after the sum
counter has reached the previous maximum net volume.
Pulse output A and B; Net forward volume
Figure 6-7: Y: Sum counter value; X: Time
1 Forward flow
2 Reverse flow
3 Net forward volume
INFORMATION!
In case of net forward volume the sum counter on the display can temporarily be different from
the net volume provided by pulse output A and B.
No. Function Options Description
20 Pulse output A 0 = Off (default) Pulse output A
1 = On
21 Pulse output B 0 = Off (default) Pulse output B
1 = On
22 Pulse output A and B:
phase shift
0 = 90° offset (default) Sets the relation between pulse
output A and B. Menu no. 20 and 21
must be set to 1 = on.
1 = Forward - reverse
2 = Net forward volume
23 Pulse output A and B:
pulse width
5 = 5 ms (default) The pulse width is always the same
for pulse output A and B.
A small pulse width means a lower
energy consumption of the battery.
10 = 10 ms
20 = 20 ms
50 = 50 ms
100 = 100 ms
200 = 200 ms
