Level and distance calibration
Level and distance calibration may be necessary when using a nozzle or pipe or if there are
disturbances in the near zone caused by a physical object.
Non-metallic (e.g. plastic) vessels and installation geometry may introduce an offset for the
zero reference point. This offset may be up to ± 25 mm. The offset can be compensated for
using Distance Calibration.
When calibrating the transmitter, it is important that the product surface is calm and that
the tank is not being filled or emptied.
