Latest Patents

Francois M Dunand holds a patent for an ultrasonic flow rate meter. This device is designed to measure the speed of a fluid in a tube using two ultrasonic electro-acoustic transducers. The system includes means for energizing these transducers with first and second transmit pulse groups. It also features means for receiving the corresponding receive pulse groups at the transducer output. The invention measures delays between the transmit and receive pulse groups, allowing for the calculation of flow rate based on these measurements. The flow rate is proportional to the quotient of the third delay by the product of the first and second delays. This innovative approach utilizes both integer and fractional delay parts for precise measurement.
