RANGE PULSE n
# 359...362
Pulse output:
Pulse output frequency is out of range. 1. Increase the setting for pulse
weighting
2. When selecting the pulse width,
choose a value that can still be
processed by a connected counter
(e.g. mechanical counter, PLC
etc.).
Determine the pulse width:
– Variant 1: Enter the minimum
duration that a pulse must be
present at the connected coun-
ter to ensure its registration.
– Variant 2: Enter the maximum
(pulse) frequency as the half
“reciprocal value” that a pulse
must be present at the con-
nected counter to ensure its
registration.
Example:
The maximum input frequency of
the connected counter is 10 Hz.
The pulse width to be entered is:
3. Reduce flow.

SIGNAL TOO LOW
# 391
Attenuation of acoustic measurement
section too high. – Check to see if the coupling fluid
must be renewed.
– It is possible that the fluid indicates
too much attenuation.
– It is possible that the pipe indicates
too much attenuation.
– Check the sensor spacing
(Installation dimensions).
– Reduce the number of traverses if
possible.
