7.9.2.6Lwr 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
The default is

7.9.2.7SoS constant - P627
The speed of sound at 0oC (32 deg F) for a particular supernatant can be programmed in m/s (ft/s imperial).
Default (metric m/s) | Default (imperial ft/s) |
1402.0 | 4599.7 |
7.9.2.8Bottom 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
