Parameters
slower response time is associated with greater reliability. Noisy applications or those
with agitators tend to be more manageable at slower response rates, as these make use
of filtering, echo verification, and longer Fail-Safe delay.
echo verification: discriminates between agitator blades in motion (spurious noise)
and the target surface (true echo).
Fail-Safe timer: establishes the period from the time a loss of echo (LOE) starts until
the Fail-Safe default (P071) is triggered. The P003 pre-set timer value can be
overridden by P070.
P004 Antenna (F = 240)
Identifies antenna configuration.
P005 Units (F = 1)
Specifies units for programming and measurement.
P006 Empty (F = 10m)
Sets the distance in units (see P005) from
flange face to empty level.
P007 Span (F = 10m)
Sets the distance from empty (P006) to full /
100% level.
Full level can be set at any measurement above the empty level.
