If the antenna diameter is smaller than the process connection size (flange):
• Make sure the flange on the nozzle is level.
• Make sure that you use the applicable gasket for the flange dimensions and the process.
• Align the gasket correctly with the flange facing of the nozzle.
• Put the device carefully on the silo flange. Do not attach the device flange to the silo yet
