摘要： A prior art device for determining at least one parameter of a flowing gas-liquid mixture has a drawback in that it does not offer any protection against liquids that move counter to the main direction of flow. The inventive device (50) has a condensation trap (36), which is arranged downstream from the measuring element (25) thus protecting the measuring element (25) against backward flowing liquids. The device is used, in particular, for determining parameters of intake air in internal combustion engines.

摘要： The invention relates to a device for measuring at least one parameter, especially the volume flow, of a medium flowing in a conduit, especially the intake air volume flow of an internal combustion engine, with at least one measuring element being situated in the flow. It is known from the prior art that constrictions that extend radially in the conduit cause acoustic disturbances that can be perceived as a whistling noise. The inventive constrictions (35, 40, 79) do not evenly reduce the cross-section of the conduit (14) and therefore do not cause swirling turbulences that are acoustically perceived as a whistling noise.

摘要： The invention relates to a method for compensating the measurement deviation of an air-flow sensor, caused by the accumulation of dirt or by ageing, said sensor being located in a flow channel. To compensate the measurement error, the sensor is impinged by a blast of air and the response time of the sensor is evaluated. The sensor error caused by the coating of dirt or ageing is then corrected based on the response time.

摘要： The invention relates to a device (1) for measuring at least one parameter of a medium that flows in a conduit (3). The device is especially used for measuring the mass of a flowing medium, the intake air mass of an internal combustion engine for instance. Liquid and solid particles that are contained in the conduit (3) influence a characteristic behaviour of a measuring element (34) which serves for determining a parameter of the flowing medium. An inventive protective grid (38) rejects liquids and solid particles from the measuring element by guiding said liquids and particles to an inner wall (8) of the conduit (3). The device (1) also stabilises the flowing medium by producing longitudinal whirls in a direction of flow.

摘要： The invention relates to a device for measuring at least one parameter of a medium that flows in a conduit and especially for measuring the volume of the suctioned air in an internal combustion engine. Liquid particles that are contained in the conduit impinge upon a measuring element and influence the characteristic curve behaviour of the measuring element which serves for detecting parameters of the flowing medium. The characteristic curve behaviour of the measuring element can be negatively changed by solid body particles. The aim of the invention is to reduce the impingement of the measuring element (23) by solid body particles. A protective grating (15) is provided. Side walls (36) of channels (43) pertaining to the protective grating (15) form different intersection angles with the direction of flow (6, 12). Solid body particles are thus guided around the measuring element (23) and into a path of movement (53).

摘要： In a first embodiment of the device described, a heated sensor element is exposed to the moving fluid and is cooled by it. The temperature of the sensor element is controlled so that it remains constant, for instance with respect to the temperature of the fluid. The heating power required to maintain the temperature of the sensor element constant is a measure of the mass of the moving fluid and is used to determine this mass. In a second embodiment, at least one resistor is located above and below the heating element and the mass of the moving fluid determined from the difference in temperature between them. The device includes means for controlling the heater current with evaluation electronics and microcontroller, the evaluation electronics and microcontroller being part of a control device which calculates additional regulation and control parameters as a function of the variable determined for the moving fluid. 00000

摘要： The invention relates to an ultrasonic flow sensor for measuring the volumetric flow of a flowing medium through a flow channel (24). Said sensor comprises a transducer array (2), which is located in the flow cross-section of the flow channel (24) and which generates ultrasonic waves (27) that are propagated in the flow cross-section of the flow channel (24) transversally to the flow direction (14) of the flowing medium. According to the invention, the ultrasonic transducer array (2) has a staggered arrangement of transducer elements (4), which act alternately as transmitting (10) and receiving antennae, in such a way that all emitted individual sonic waves (27) interfere to form common wave fronts (28).
