摘要： Operational configuration and temperature compensation methods are provided for bulk acoustic wave (BAW) resonator devices suitable for operating with liquids. Temperature compensation methods dispense with a need for temperature sensing, instead utilizing a relationship between (i) change in frequency of a BAW resonator at a phase with adequate sensitivity and (ii) change in frequency of a phase that is correlated to temperature. Operational configuration methods include determination of an initial phase response of a BAW resonator in which temperature coefficient of frequency is zero, followed by comparison of sensitivity to a level of detection threshold for a phenomenon of interest.

摘要： A liquid dispensing apparatus for dispensing droplets of a liquid, and methods for measuring various fluid parameters of the liquid are described. The liquid dispensing apparatus comprises a container having a chamber for holding a liquid. An orifice is positioned at an end of the chamber for dispensing droplets of the liquid, the orifice being configured to retain the liquid in the container if the container is positioned with the orifice facing in a downward direction. An acoustic transducer means is at least partially positioned in the chamber for periodically propagating a focused acoustic beam toward the orifice and through at least some of the liquid while the liquid is contained in the chamber, with the focused acoustic beam being capable of causing a droplet of the liquid to be ejected from the orifice when a free surface of the liquid is within the depth of field of the acoustic transducer means. Fluid parameters that can be measured include the sound velocity in the liquid, liquid level and liquid concentration, liquid acoustic impedance, liquid density ultrasonic attenuation and ultrasonic viscosity.

摘要： There is described a method and device for measurement of the specific density of a gaseous or liquid medium, whereby a pulsed acoustic signal is injected into the measured medium by means of a transmitting transducer, the signal is detected by a receiver transducer, after passing over a measured path, whereupon the acoustic impedance Z is automatically determined in an analytical device by comparison of a curve for the currently measured received signal with reference curves, predetermined for various values of the acoustic impedances stored for each value of the acoustic impedance, whereby the propagation speed c of the acoustic signal in the medium is determined and the density p of the medium is calculated as the quotient from the acoustic impedance Z and the propagation speed c. The method is preferably of application to an ultrasound mass flow measurement device and hence has the advantage that no additional density sensor is required, nevertheless permitting a robust and precise measurement of density.

摘要： A method for determining the density of a fluid in a pipe. The method includes determining a first, second, and third reference reading of a pipe using a transmitter transducer, a receiver transducer, and a primary receiver transducer. The first reference reading is determined when the pipe is empty. The second reference reading is determined when the pipe contains a reference liquid of known sonic impedance. The third reference reading is determined when the pipe contains an unknown liquid. The liquid sonic propagation velocity of the unknown liquid is measured. The relationship of an impedance of the unknown liquid in relation to the impedance of the reference liquid is determined. Finally, the density of the unknown liquid is determined using the determined relationship of the unknown impedance to the known impedance of the reference liquid divided by the measured liquid sonic propagation velocity of the unknown liquid.
