  • Measurement Of Velocity Or Position Using Acoustic Or Ultrasonic Waves (AREA)

Abstract

PURPOSE: To enable high-accurate measurement with a compact device, by using a microcomputer to measure the temperature and constants of a medium and the time from the transmission of ultrasonic waves to their reception.
CONSTITUTION: A microcomputer 1 performs calculation and processing and controls each appliance. Ultrasonic tone burst waves are emitted from a transmitting section 2 in accordance with an instruction from the computer 1. The transmitting section comprises an oscillator 2a, a tone burst generation circuit 2b, an amplifier 2c and a transmission head 2d. A receiving section 3 informs the computer 1 that the received level of the ultrasonic tone burst waves emitted from the transmission head 2d and reflected reaches a prescribed value. The receiving section comprises a reception head 3a, an amplifier 3b, a slice circuit 3c and an interrupt circuit 3d. Clock pulses P from a clock oscillator 4a are counted by an ultrasonic wave reflection time measuring section 4. The velocity of sound wave propagation is compensated as to temperature by a temperature measuring section 5.
