Recommended action
Ensure that Product Level Range
has valid ranges and units
assigned.
Change the sensor housing
Verify that correct Measured
Product (Two Liquid(Flooded) or
Two Liquid (Non Flooded)) and
the Surface and Interface
configuration of Correlation
Algorithm parameters and Sensor
parameters configuration
Ensure that Auxiliary Transducer
block is in AUTO mode.
Verify that correct Measured Type,
Dielctric constant, Sensor height,
Maximum Product Height, Probe
Type, Probe Length and Blocking
Distance High and Low values are
assigned.
Verify that correct Correlation
Algorithm Surface and Interface
values are assigned by reading
Echo curve again.
