Abstract: A transducer for non-invasive measurement includes: a shear-type piezoelectric element; and a host material. The shear-type piezoelectric element is mounted to a first face of the host material. A second face of the host material is mountable to a wall of a vessel that holds a liquid. When the second face of the host material is mounted to the wall of the vessel, the transducer when activated at an activation frequency launches a Lamb wave into the wall of the vessel. The transducer is designed such that a phase velocity of the Lamb wave in the wall of the vessel is greater than a speed of sound in the liquid held by the vessel.

Abstract: A system and a method for measuring a signal propagation speed in a liquid contained in a vessel or in a gaseous medium contained in the same vessel above the surface of the liquid are proposed. A transmitter transmits a first signal in a first direction which is at an acute or right angle to a first reflective surface, wherein the first reflective surface reflects the first signal so that it travels in a second direction is received by a first acoustic or electromagnetic receiver. The transmitter transmits a second signal in a predetermined third direction which is at an acute angle to the first direction, where the first or a second reflective surface reflects the second signal so that it travels in a predetermined and angular fourth direction with respect to the first or second reflective surface and is received by the first or a second acoustic or electromagnetic receiver. The speed of sound is then determined under the assumption that both the first and the second signals travel at the same average speed.

Abstract: A transducer for non-invasive measurement includes: a piezoelectric element; a base plate; and driver electronics. The piezoelectric element is mounted to a first face of the base plate. A second face of the base plate is mountable to a wall of a vessel that holds a liquid. The driver electronics drive the piezoelectric element at a plurality of activation frequencies. When the second face of the base plate is mounted to the wall of the vessel, the transducer when activated excites acoustic waves in the base plate and to launch an acoustic wave into the liquid. The transducer is designed such that an angular divergence of the acoustic wave launched into the liquid varies as a function of at least the activation frequency and a dimension of an emitter.

Abstract: A system and a method for non-intrusive and continuous level measurement of a liquid enclosed by a solid wall of a vessel. The system comprises an ultrasonic transmitter for generating an ultrasound wave and for emitting it into the vessel wall, an ultrasonic receiver for receiving the ultrasound wave, and an electronic control and data processing unit (ECDU) for controlling operation of the transmitter and of the receiver and for determining the liquid level. The transmitter is able to emit the ultrasound wave as a primary Lamb wave into the vessel wall so that a part of the primary Lamb wave leaks from the vessel wall into the liquid in form of a pressure wave. The ECDU is adapted to repeatedly determine the time of flight of the pressure wave, change the ultrasonic frequency of the transmitter until the determined time of flight reaches a minimum, and determine the liquid level.
