Abstract

PURPOSE:To eliminate errors in time measuring due to sensing errors, in the case when the time length from the time point of transmission of an ultrasonic pulse to the time point of reception is deviated from the average measured time length by a specified value, by nullifying the time point of reception of at this time. CONSTITUTION:An SRFF 20 is under the set state during the time length from the time point of the transmission of the ultrasonic wave pulse to the time point of the reception thereof. Only the clock signal fo in this time length is counted by a counter 23. Said counting is performed every repeating between the counted value M and the average value is obtained. If said difference exceeds a specified value, a judging signal J is outputted, and used as a signal which nullifies the received signal in the time measuring circuit.
