ABSTRACT:
An ultrasonic method and apparatus for measuring liquid level in a vessel employing an acoustic waveguide (16) connected to an ultrasonic transducer (14) and the vessel (18). Guiding means (24) situated inside a vessel (18) directs the acoustic energy pulse to a surface (22) of the liquid. The acoustic energy pulse is reflected from the surface (22) and returned along the guiding means (24) to the acoustic waveguide (16). A pulser/receiver (10) connected thereto measures the reflected acoustic energy pulse for determining liquid level from the transit time.
