An example fluid parameter sensor and meter is disclosed to measure at least one parameter of a fluid. In an example, the fluid parameter meter includes an outer conduit, A sensor element assembly is disposed in the outer conduit and having a plurality of sensor elements to convey the fluid inside of the sensor element assembly. At least one mounting flexure is fixedly attached to the sensor element assembly and to the outer conduit. The at least one mounting flexure is configured to enable the sensor element assembly to vibrate in a radial motion. At least one vibration driver causes the sensor element assembly to vibrate in the radial motion. At least one vibration sensor senses the radial motion of the sensor element assembly. Controlling electronics measure at least one parameter of a fluid based on said radial motion.

This disclosure relates to detecting fluid in medical tubing. In certain aspects, a method is performed by a data processing apparatus. The method includes controlling repetitive activation of the ultrasonic transmitter. The method also includes receiving a signal from the ultrasonic receiver during an activation of the ultrasonic transmitter. The method also includes determining that fluid is absent or present in a portion of the medical fluid tube based on a comparison between the signal and a threshold value.

A method is provided for non-invasively determining properties of a multiphase flow which flows through an electrically conductive object. Using a single set-up having a plurality of EMAT transducers, at least one property of the multiphase flow is determined by means of at least one of a plurality of measurement methods. A device is also provided for non-invasively determining properties of a multiphase flow which flows through an electrically conductive object. At least four EMAT transducers are positionable upstream along a first object cross-section at or near the object wall and at least four EMAT transducers are positionable downstream along a second object cross-section at or near the object wall.

Disclosed are a system and method for evaluating a tissue sample that has been removed from a subject. Movement of fluid through the tissue sample is monitored by measuring time of flight of acoustic waves passed through the tissue sample. A system for performing the method can include a transmitter that outputs the energy and a receiver configured to detect the transmitted energy. Using the disclosed method and system, an optimized protocol for ensuring adequate distribution of the fluid throughout a variety of tissue types and/or sample sizes can be developed and utilized.

Systems, techniques, and computer-implemented processes for acoustic signal based improvements to one or more process steps in the manufacture of battery cells. Information gathered based on an acoustic signal based analysis in one process step can be used in one or more other process steps using any suitable combination of feedback and/or feedforward of the acoustic signal based analysis. Such feedback and/or feedforward can improve the overall quality of battery cells produced using the manufacturing process, efficiency/cost of the manufacturing process, improvement in yield/reduction in wastage of the battery cells produced using the manufacturing process and/or improvements in individual process steps.

A method for determining and/or monitoring a concentration of maltodextrin and/or maltose in a mashing process comprises method steps as follows: providing a mash, heating the mash to at least one predeterminable temperature, determining the density of the mash determining the velocity of sound in the mash, ascertaining a concentration of maltodextrin and maltose in the mash, and ascertaining the concentration of maltodextrin and/or maltose in the mash.
