Sonic Tracker II™
The Sonic Tracker II (Figure 1-17) measures and
controls the elevations of the screed, and should be removed at the
end of each day for proper storage in the carrying case. The Sonic
Tracker contains no manual adjustments, and may require periodic
maintenance of the transducer.
The Sonic Tracker measures distance, controlling grade from a
physical grade reference, such as a curb, stringline or existing road
surface. A transducer, located in the bottom of the Tracker, generates
sound pulses like a speaker and listens for returned echoes like a
microphone.
