Abstract: A measurement system for determining a density ρ or a compressibility κ of a liquid medium in a vessel includes: at least one pressure sensor for measuring a hydrostatic pressure Δp of the liquid medium as a measured hydrostatic pressure Δp; at least one ultrasound sensor for measuring a first time of flight t1 along a first propagation path comprising a point at a level surface of the liquid medium, and for measuring a second time of flight t2 along a second propagation path, which is different from the first propagation path; and a control unit for determining the density ρ or the compressibility κ of the liquid medium based on the measured hydrostatic pressure Δp, the first time of flight t1, and the second time of flight t2.

Abstract: A water treatment device including a first hydrocyclone and a biocidal fluid injector is described. The first hydrocyclone has an internal space, a water inlet for supplying water into the internal space, a base outlet for discharging at least a part of the water, and an apex outlet. The biocidal fluid injector is configured to inject a biocidal fluid into the internal space for eliminating organisms present in the water. The biocidal fluid injector is positioned such that a pressure within the injected biocidal fluid is lower than a head pressure of the first hydrocyclone.

Abstract: A plasma reactor for a Dielectric Barrier Discharge (DBD) system, the system includes one or more plasma reactor modules, the one or more plasma modules are configured as transmission lines. A duration of a rise-time and/or a fall-time of a voltage pulse, fed into a first end of the one or more reactor modules is shorter than a run-time of the voltage pulse from a first end of the one or more reactor modules to a second end of the one or more reactor modules.

Abstract: A measurement system for measuring an inhomogeneity of a medium in a vessel includes: a first ultrasound emitter for sending a first ultrasound signal along a first path; a second ultrasound emitter for sending a second ultrasound signal along a second path different from the first path; a first ultrasound receiver for receiving the first ultrasound signal and measuring a first measurement parameter p1 of the received first ultrasound signal; a second ultrasound receiver for receiving the second ultrasound signal and measuring a second measurement parameter p2 of the received second ultrasound signal; and a control unit: receives the first measurement parameter p1 from the first ultrasound receiver, receives the second measurement parameter p2 from the second ultrasound receiver, and determines a ratio p1/p2 of the first measurement parameter p1 to the second measurement parameter p2.

Abstract: A signal processing unit configured to: cause a first ultrasound emitter, when attached to a wall of a vessel, to emit a first ultrasound test signal; receive, from at least one ultrasound receiver, when attached to the wall of the vessel, the first ultrasound test signal; detect a time of flight of the received first ultrasound test signal; and determine that an acoustic coupling of the first ultrasound emitter and a first ultrasound receiver of the at least one ultrasound receiver to the wall of the vessel is intact if the detected time of flight corresponds to a length of a path in the wall of the vessel from the first ultrasound emitter to the at least one ultrasound receiver.
