7.9.2.6 Lwr S-nat Temp – P626
This value is used for temperature compensation if the measured supernatant temperature is below this value.
The lower temperature (P626) must always be less than the upper (P625).
Valid entries are between –40 and +85°C (-40 to 185 deg F).
The default is -5°C (25 deg F)

7.9.2.7 SoS constant - P627
The speed of sound at 0
o
C (32 deg F) for a particular supernatant can be programmed in m/s (ft/s imperial).

7.9.2.8 Bottom Blanking – P628
This parameter allows the user to program a region close to the bottom of the tank which is not used by the
system for normal blanket level measurement.
This is useful if there are any fixed obstructions in front of the transducer close to the bottom of the tank which
cannot be moved or otherwise avoided.
The default value is 0.0 metres / 0 foot

7.9.2.9 Level Offset – P629
This parameter is used to provide an offset to the normal displayed sludge blanket level (D800). The value may
be entered as a positive or negative value to provide the required offset to the normal displayed sludge blanket
level.
Default is 0.0.
