is the
sound speed stored in the database.

For further information see section 13.6.
A lower limit for the flow velocity can be entered (see section 13.5).
An upper limit for the flow velocity can be entered (see section 13.4).

(zero) to deactivate the flow velocity check.
Select the overflow behavior of the totalizers (see section 13.3.1).
Select
on
to keep the previous totalizer values after a restart of the measurement.
