S 437
Configuration
The sound velocity is outside the search
range of the transmitter.
– Check the installation dimensions.
– If possible, check the sound velocity of the fluid or check the
specialist literature.
If the actual sound velocity is outside the defined search range, the
corresponding parameters must be changed in the LIQUID DATA
function group.
More detailed information on this is provided in the SOUND
VELOCITY LIQUID function (
100).
Notice
(–)
The pipe transmitted wave may
superpose the signal. We recommend
you alter the sensor configuration in the
event of this error message.
"
Caution!
A change of the sensor configuration is
required if the measuring device
indicates zero or low flow.
– In the SENSOR CONFIGURATION function, change the number
of traverses from 2 or 4 to 1 or 3 and mount the sensors
accordingly.

Signal output
Current output:
The current flow is outside the set range.
– Change the upper or lower limit setting, as applicable.
– Increase or reduce flow, as applicable.
Notice
(–)
Pulse output:
Pulse output frequency is out of range.
1.
Increase the setting for pulse weighting.
2.
When entering the pulse width, select a value that can still be
processed by an external totalizer (e.g. mechanical totalizer,
PLC, etc.).
Determine the pulse width:
– Version 1: Enter the minimum duration that a pulse must be
present at the connected counter to ensure its registration.
– Version 2: Enter the maximum (pulse) frequency as the half
"reciprocal value" that a pulse must be present at the
connected counter to ensure its registration.
Example:
The maximum input frequency of the connected totalizer is
10 Hz. The pulse width to be entered is:
