6.3.7 Pulse output - PULSE OUT/M19
All the possible settings for the pulse output can be found in this menu item. This menu item
can only be selected if your device is fitted with this option.
6.3.8 Min/Max memory - MIN MAX/M20
The panel meter can save a minimum and a maximum measured value. The input signal or
the signal processed using the linearization table are available as the signal source. The
memory is reset manually or using the digital input (→ ä 24).
The scaling constant C must always refer to Q in m
3
/h, i.e. C has to be converted if Q
is available in another flow unit.
Examples:
• Q in l/h with C = 2.11
1 l/h = 0.001 m
3
/h
C = 2.11 * 0.001 = 0.00211
• Q in USKgal/s with C = 0.35
1 USKgal/s = 13627.4444 m
3
/h
C = 0.35 * 13627.4444 = 4769.60554
A table with values for converting the various flow units to m
3
/h is provided in the
appendix.

Pulse value with which the pulses should be output at
the output.
Pulse width 0.04 to 2000ms
1000.00
Sets the pulse width at the pulse output.
The maximum output frequency depends on the pulse
width.
f(max) = 1/(2*pulse width)
