The invention relates to a measurement apparatus (10) and to a method for the determination of a flow rate (v) and/or of a throughflow (Q) of a fluid (14) flowing in a conduit (12) comprising at least one first ultrasonic transducer (18) and one second ultrasonic transducer (20) that permit a flow rate determination via the time of flight of an ultrasound signal. To further improve the determination of a flow rate of a fluid using ultrasonic transducers, in particular at very high flow rates, and to enable the measurement of very high flow rates, it is proposed that a noise-measuring ultrasonic transducer (18, 20; 24) is provided that measures the noise generated in on the flowing past of the fluid (14) in the ultrasonic transducer and a control and evaluation device (32) is configured to determine the flow rate (v) using the noise measurements.

Processing electronics provide flow data acquisition and telemetry for multiphase flow tomographic ultrasonic transceiver arrays. The processing electronics forms pulse drive signals to cause a tomographic pulse sequence to be emitted. Selected ones of an array of the ultrasonic transceivers emit ultrasonic energy in the tomographic pulse sequence for travel through the multiphase flow. The selected transmitting transceiver is isolated while transmitting it, and the remaining the transceivers are enabled to receive measures of the emitted pulse is after travel through the multiphase flow.

A multiphase flowmeter for detection of fluid flow by monitoring of vortex frequency or perturbation time of flight. The flowmeter includes a bluff body to facilitate formation of vortices during a consistent phase of a flowing fluid. Thus, monitoring frequency of the vortices may be employed to ascertain flowrate. Further, the bluff body may also facilitate formation of perturbations during transitioning phase of the fluid and include perturbation sensors at multiple known locations along the flow-path. Thus, analysis of perturbation detection times at the different locations may be used to ascertain flowrate even in the absence of vortices.

A combined sewer/enclosure overflow (CSO) sensor system is described for accurate detection and measurement of overflow events. From the combined data, trending information can determine if there is debris accumulation. Rain masks can be used in the trending data to measure overall health. External sensors in combination with the CSO sensors provide predictive information and additional levels of information/data accuracy. The sensor system automatically and remotely monitors CSO locations and provides real-time data regarding start times, stop times, duration, and flow volumes of overflows that occur in these structures and provide regulatory and public notification of these events.

A smart bottle comprising a lid and container body includes a fluidic oscillator, an actuator, a drinking interface, a sensor comprising a microphone, a processor, an antenna and a battery disposed in the smart bottle. The smart bottle utilizes the various components to measure liquid consumption of a user in one or more drink events.
