The Sonic Tracker IITM measures and controls the elevations of the cylinder. A transducer, located in the bottom of the Sonic Tracker II, generates sound pulses like a speaker and listens for returned echoes like a microphone. The Tracker measures the distance, controlling grade from a physical grade reference, such as a curb, stringline, or existing road surface. A temperature bail compensates for rapid air temperature changes. In milling applications, always use a temperature bail. Figure 1-4
