Abstract: An ultrasonic flow meter includes a meter housing, a first ultrasound transducer, a second ultrasound transducer, an electronic control arrangement for operating the ultrasonic flow meter, and a connection arrangement being arranged between the electronic control arrangement and the ultrasound transducers. The connection arrangement includes an electrically insulating support arrangement, and a set of elastic connectors for electrically connecting the electronic control arrangement with the first and second ultrasound transducers. The insulating support arrangement mechanically fixates the set of elastic connectors and maintains electrical separation between the set of elastic connectors.

Abstract: An ultrasonic flow meter configured to measure a flow within a conduit configured for autozeroing during active flow operation of the flow meter. The flow meter includes a printed circuit board including circuitry for conducting ultrasonic transit time flow measurements, the printed circuit board including transducer swap relays and first and second transducer cables connecting the first and second transducers, respectively, to the transducer swap relays. The flow meter further includes a programmable processor configured to generate flow measurement data based on an ultrasonic flow meter calibration performed by the ultrasonic flow meter in situ while measuring flow through the conduit. Calibration includes determining a zero offset value, determining a swap offset value by measuring transit time forward and backward between the first and second transducers through the flow in the conduit, activating the transducer swap relays to physically swap the first and second transducers, and measuring transit time forward and backward between the swapped first and second transducers through the flow in the conduit, determining a flow zero value based on the zero offset and swap offset, and generating flow rate data based on the flow in the conduit and the flow zero offset.

TL;DR: In this article, the relationship between pressure or voltage loss and bubble diameter has been studied by simulation results and experimental results, respectively by the ultrasonic transmission method, and both results showed that the transmission-mode measurement method has good resolution on the bubble diameter.
Abstract: Non-invasive ultrasonic tomography is a practical solution of extracting cross-section information regarding the process of two-phase flow. For gas/water two-phase flow, the ultrasonic energy would be reflected about 99.94% at the gas/water interface due to the great differences between the acoustic impedance of water and gas. In this paper, the relations between pressure or voltage loss and bubble diameter has been studied by simulation results and experimental results, respectively by the ultrasonic transmission method. Both results showed that the transmission-mode measurement method has good resolution on the bubble diameter.
