摘要： A rodless guide microwave radiation device, system, and method is disclosed for measuring at least one characteristic of a liquid in a vessel. A hollow metal waveguide conveys microwave radiation and is adapted to be disposed in a vessel for containing a liquid, the waveguide having a first end and a second end. A single chip radar sensor mounted on a PCB is disposed proximal to the first end of the hollow waveguide. The radar sensor is configured to transmit millimeter wavelength signals into the first end of the hollow waveguide for propagating down the waveguide toward the second end, and receive a return echo from the signal based upon a change in impedance upon encountering the liquid and propagating in the reverse direction of the waveguide, the single chip radar sensor including electronic circuitry for determining at least one characteristic of the liquid located in the waveguide based on detection of an impedance change according to time domain reflectometry. A mount assembly is configured to position the single chip radar sensor mounted on the printed circuit board over the first end of the hollow waveguide for transmitting and receiving the microwave radiation via the hollow waveguide; and a barrier structure sealingly protects the single chip radar mounted on said printed circuit board from exposure to contaminants within the hollow waveguide, while permitting microwave propagation between the single chip radar and the liquid through the hollow waveguide. In embodiments, the waveguide may be rigid, bent, curved, or flexible, and the radar and PCB may be outside or within the waveguide.

摘要： The present disclosure relates to a fastening device for fixing a radar-based fill level gauge to an outer grating of an intermediate bulk container tank. The device comprises a clamping retainer, which can be clamped to a grating bar of the outer grating, and an adapter having a first fastener configured such that the fill level gauge can be mounted detachably on the adapter. The adapter also includes a cut-out, through which radar signals of the fill level gauge can be sent towards the filling material when in the mounted state. In addition, the device comprises a second fastener configured such that the fill level gauge can be fastened indirectly to the clamping retainer. According to the present disclosure, the outer grating is used to fasten the fill level gauge to the container.

摘要： Embodiments described herein generally relate to devices, systems and methods for measuring the dose remaining in a drug delivery device that is used for delivering a dose to a patient. In some embodiments, a dose measurement system for measuring the liquid volume in a container includes a plurality of light sources which are disposed and configured to emit electromagnetic radiation toward the container. A plurality of sensors are located in the apparatus that are optically coupleable to the plurality of light sources and are disposed and configured to detect the electromagnetic radiation emitted by at least a portion of the light sources. The apparatus also includes a processing unit configured to receive data representing the portion of the detected electromagnetic radiation from each of the plurality of sensors. The processing unit is further operable to convert the received data into a signature representative of the electromagnetic radiation detected by the plurality of sensors.
