Measurement from the outside through plastic walls
• If possible use the 250 mm (10 in) antenna.
• The distance between the lower edge of the antenna and the tank should be about 100 mm (4 in).
• If possible, avoid mounting location where condensation or build-up might occur.
• In case of outdoor mounting, the space between antenna and vessel has to be protected from the
elements.
• Do not mount any potential reflectors (e.g. pipes) outside the tank in the signal beam.
