Measuring range, accuracy, and cone dimensions
When selecting cone antenna dimension, it is generally recommended to use as large
antenna diameter as possible.
Standard cone antennas are available for 4-, 6- and 8-in. tank openings. The 4- and 6-in.
cones can be extended to fit long tank nozzles.
Level accuracy is up to ±2 mm (0.08 in.) for 8-in. cone antennas. For 4- and 6-in. cone
antennas accuracy depends on installation conditions.
Measuring range
8-in. Cone: 0,8 to 20 m (2.6 to 65 ft) below flange. (Possibility to measure 0,4 to 30 m (1.3
to 100 ft). Accuracy may be reduced.)
6-in. Cone: 0.8 to 20 m (2.6 to 65 ft) below flange. (Possibility to measure 0.3 to 25 m (1 to
80 ft). Accuracy may be reduced.)
4-in. Cone: 0.8 to 15 m (2.6 to 50 ft) below flange. (Possibility to measure 0.2 to 20 m (0.7
to 65 ft). Accuracy may be reduced.)
