ABSTRACT:
An ultrasonic flowmeter casts an ultrasonic pulse toward a measurement line ML, processes ultrasonic echo signals, and calculates the position and speed of each ultrasonic reflector positioned along the measurement line ML by analyzing the ultrasonic echo signals subjected to signal processing. The flowmeter filters the ultrasonic echo signals. A trigger oscillator of the flowmeter controls signal transmission/reception timing according to an adjustable sequence wherein one cycle is formed of three consecutive sets of emissions of an ultrasonic pulse and reception of ultrasonic echo signals, and a waiting period of time.
