P876 Rate Distance
This parameter is the rate
Measurement Units
(
P104
) over which the
material level must change before the
Rate
Value
(
P877
) is updated. If the
Rate Time
(
P875
) expires before the
Rate Distance
(
P876
) is exceeded,
then the
Rate Value
(
P877
) will be updated immediately.
Default = 0.05m
P877 Rate Value
This parameter displays the current rate of change of material level, in
Measurement Units
(
P104)
per minute. It is read only.
P878 Lower Cutoff
This parameter is used to select the minimum Rate to be calculated and can
be used to eliminate unwanted updates from effects of ripples/waves on the
surface of the material.
Filters
The following three parameters can be used to filter out unwanted changes
of level caused by a ‘rippled’ or agitated surface.
P880 Gate Mode
This parameter determines the operation of the gate, which is established
around the processed echo and is used to track the echoes movement and
update the display. If set to
Fixed
, P880 = 0 (
Default
) then the width of the
gate is determined by the value of
P881 Fixed Distance
. When set to
Calculated,
P880=1 then the gate width is automatically calculated and
updated
according to the values of
P870, P871, P874, P875 and P876.
Please consult Pulsar for further information and assistance on changing the
value of this parameter.
P881 Fixed Distance
This parameter determines the width of gate to be used in tracking an echo
and under normal circumstances will not require changing, but it can be
increased in the cases where the surface is moving extremely fast (in excess
of 10m/min) to ensure smooth processing of the changing level.
