摘要： A device for measuring the mass of a flowing medium which avoids measuring liquid components entrained in the medium. The device includes an interrupting body, which is accommodated upstream of the device, in a section of an air intake line that tapers in the flow direction, in order to filter out liquid components entrained in the flow by means of the interrupting body and to divert the liquid components from the measuring device. The invention is provided for measuring the mass of a flowing medium, in particular for measuring the intake air mass of internal combustion engines.

摘要： A devices for measuring the mass of a flowing medium, having a temperature-sensitive measuring element, in which accurate medium flow measurement can be made in the presence of a pulsating flow which is characterized by flow fluctuations. In order to provide accurate measurements, the device has a structure which is installed in the measuring conduit in a region of its inside wall upstream and downstream of the measuring element. The structure has friction faces exposed to the oncoming flow in which the friction faces effect a flow resistance which can be varied by the intensity of the flow fluctuations, only in the presence of a pulsating flow, so that the flow is positively displaced more or less into the region of the measuring element, in order to increase the flow velocity and to compensate for the measurement errors. The invention is for measuring the mass of a flowing medium in the intake of an internal combustion engine.

摘要： A plug-in sensor for determining an aspirated air mass of an internal combustion engine flowing through a flow pipe has a plug part, which is able to be introduced into the streaming medium with a specified orientation to the main flow direction. Provided in this plug part is at least one flow channel having at least one inlet opening and at least one outlet opening. Accommodated in the at least one flow channel is at least one sensor for determining the at least one parameter. The plug part has a rounded inflow side, which points counter to the main flow direction. The plug part at least partially has an airfoil profile, which is designed such that an asymmetrical flow profile of the fluid medium comes about when the plug part is introduced into the streaming fluid medium.

摘要： A method is provided for operating a hot-film air-mass sensor, which can be used especially for measuring air mass flows in the intake tract of an internal combustion engine. The hot-film air-mass sensor has a sensor chip having a sensor frame and a sensor diaphragm having at least one heating element and at least two temperature sensors, a chip carrier for holding the sensor chip and at least one additional heating element. The sensor chip is able to be heated up using the at least one additional heating element. Immediately after shutting down the internal combustion engine, the at least one heating element of the sensor diaphragm is switched off, or is switched to a lower heating power. Furthermore, the at least one additional heating element is switched on for a specified postheating phase. The provided method is particularly suitable for avoiding oil contamination of the hot-film air-mass sensor.

摘要： An ultrasonic flow rate meter and a method for measuring the flow rate with the aid of ultrasound are described, having at least two ultrasonic transducers situated offset in a flow channel in the flow direction for transmitting and receiving ultrasound wave packets, so that ultrasound propagation times from one of the ultrasonic transducers to the other, and vice-versa, can be determined in an electronic part, and having a pressure sensor associated with the flow channel for determining the pressure in the flow channel. Measured values for an engine control that is as accurate as possible are determinable by accurately detecting the incoming air in the intake of a motor vehicle internal combustion engine.
