Display Question Answer
Units
What units of measurement will be used?
Will the unit measure in Level or Volume?
What are the Volume units?
What is the relationship between Level and Volume? (Enter up to 20 points)
Sensor Offset
What is the distance from the top (100%) of the tank and the Sensor Reference point?
(bottom of NPT thread, top of BSP thread, or face of flange?)
Tank Top Is the Tank Top: Flat, Horizontal Cylinder, Dome, Irregular or Other (non-metallic)?
Tank Height
What is the tank height?
NOTE: Sensor Offset + Tank Height = Distance from process connection to tank bottom.
Blocking Distance
Default of 15" (375 mm) is the minimum distance from the process connection to the
maximum level. Extend this value when necessary to block reflections from objects
close to the antenna.
Level Offset
Is there a region at the very bottom of the vessel that cannot be measured due to heating
coils, angle tank bottom, etc.?
Dielectric What is the dielectric of the process medium?
Turbulence Is turbulence a consideration?
Foam Will there be foam on the surface?
Rate of Change What is the maximum rate the level will rise or fall?
4.0 mA Setpoint What is the 0% reference point for the 4.0 mA value?
20.0 mA Setpoint What is the 100% reference point for the 20.0 mA value?
