Abstract: A consumption meter, e.g. a water or heat meter, for measuring a flow rate of a fluid supplied in a flow tube. First and second ultrasonic transducers are arranged at the flow tube for transmitting and receiving ultrasonic signals transmitted through the fluid and operated by a flow measurement sub-circuit for generating a signal indicative of the flow rate of the fluid. A noise measurement sub-circuit operates a sensor arranged at the flow tube for detection of acoustic signals of the flow tube, and being arranged to generate a signal indicative of a noise level of the flow tube accordingly. This sensor may comprise a separate transducer, or the sensor may be constituted by one or both of the first and second ultrasonic transducers. The consumption meter may communicate data representative of the noise level via a communication module along with data consumed amount of water, heat etc.

Abstract: The invention concerns a device for localization of stereotactic coordinates by available MRI, CT, PET and angiogram imaging equipment in relation to known art animal stereotactic frames comprised of a pair of bars held in spaced parallel relation to each other by a cross bar that may be fixed to an operating table or the like by means of a fixing device, which connects to the instrument. The instrument may be detached from the stereotactic frame to allow for the imaging procedures. The instrument is made of non-magnetic and radiolucent material allowing for the use of magnetic material and radio-opaque stereotactic frames in combination with available MRI, CT, PET, and angiogram imaging equipment.
