There are additional settings for special operating conditions like:
- FiltArray:
A digital low pass filter for phase shift measurement can be configured. The Filt Array number is equal
to number of filtered measurement cycles. Shortest measurement cycle time is two sensor oscilla-
tions. This filter is very useful for applications with pulsating flow rates (piston pumps).

- TFlow:
Digital damping value for display and analog outputs (flow rate).
TFlow
is response time in X.XX
seconds.
- FiltBand:
Flow rate filter band in percentage of half nominal sensor flow rate. Depending on software verion,
slight and insignificant deviations of this flow rate may be given. Response time outside filter band is
shortest. Inside of this, the adjusted response time TFlow is active.
