Accuracy over measuring range
The measuring range is limited by the blind zone at the very top of the tank. In the blind
zone, the accuracy exceeds ±0.20 in. (±5 mm) and measurements may not be possible.
Measurements close to the blind zone will have reduced accuracy (see
For the extended cone antennas, the reduced accuracy zone ends 11.8 in. (30 cm) below
the antenna end.
The accuracy in still pipe/chamber installations depends on how well the antenna size
matches the pipe size. For more details, refer to the Best Practices for Using Radar in Still
Pipes and Chambers

Vibration resistance
• 2 g at 10-180 Hz according to IEC 61298-3, level "field with general application"
• IACS UR E10 test 7
For compliance with these standards, the transmitter housing must be fully engaged into
the sensor module. This is achieved by rotating the transmitter housing clockwise to
thread limit.
