Abstract: A thermal flowmeter comprises a heating element thermally coupled to a flowing medium, a first temperature sensor and second temperature sensor. The first temperature sensor detects a flowing medium temperature in a region not affected by the heating element. The second temperature sensor detects a temperature of the heating element and also serves as a heating element. A control unit controls heating power of the heating element based on the difference between the detected temperatures at a predetermined time. The control unit provides a square wave signal to the second temperature sensor so that in a high phase it acts as heating element and in a low phase as a temperature sensor.

Abstract: A magnetoinductive flowmeter for measuring the flow rate of a flowing, conductive medium with a capacitive measuring apparatus for detecting empty pipes is provided.

Abstract: A magnetic-inductive flowmeter with a nonconductive measuring tube, a magnetic field generating apparatus, two measuring electrodes conductively coupled to the medium for tapping a measuring-circuit voltage induced in the flowing medium, and with a measuring device for detecting an empty tube. Detection of an empty tube is obtained by the measuring device being an admittance measuring device having a detector, a counter-electrode, an ac signal source and an evaluation unit, the detector having an electrode connected to the ac signal source so that the electrode is exposed to an ac signal in the range of roughly 50 MHz-200 MHz and then an electrical field extends from the electrode into the medium. The electrode of the detector and the counter-electrode planiform shaped and are located essentially opposite one another on the outer surface of the measuring tube above and underneath the longitudinal axis of the measuring tube, respectively.

Abstract: An imaging device has a gantry designed to movie along the floor of a room in which the imaging device is installed. The imaging device has a supply unit that includes a transfer arrangement to transfer power and/or data and/or coolant between a stationary supply source and the movable gantry. The supply unit is arranged in or on the floor.

Abstract: A camshaft adjuster for an internal combustion engine of a motor vehicle, including a stator which can be driven by a crankshaft of an internal combustion engine and is located radially on the outside, a rotor which is non-rotatably connected to a camshaft and located radially on the inside, working chambers which are disposed between the rotor and stator and can be subjected to a pressure such that the rotational position of the rotor relative to the stator can be varied, and at least one sealing cover which laterally delimits the working chambers and rests against the stator and/or rotor. The sealing cover, stator and/or rotor have a convex, concave or conical contact surface, and the sealing cover can be elastically deformed by the attachment via the contact surface such that it rests against the stator and/or rotor with an increased sealing force as a result of elastic deformation.
