Latest Patents

Robert Schäfer holds a patent for a "Method and device for acoustic measurement of the specific density of a gaseous or liquid medium." This invention describes a method where a pulsed acoustic signal is injected into the measured medium using a transmitting transducer. The signal is then detected by a receiver transducer after traversing a measured path. The acoustic impedance is automatically determined by comparing the received signal with reference curves stored for various values of acoustic impedances. This method allows for the calculation of the medium's density as the quotient of the acoustic impedance and the propagation speed of the acoustic signal.
