摘要： A sensor system for measuring a velocity of a fluid flowing through a channel includes a heating element for heating the fluid. The heating element is provided with a predetermined level of power during operation. The sensor system further includes a primary electronic circuit having a primary resonance frequency which is temperature dependent. The temperature of the primary electronic circuit is determined by heat transferred from the heating element to the fluid flowing through the channel. In addition, the sensor system also includes a transducer arrangement configured to generate a measurement signal indicative of the velocity of the fluid flowing through the channel. The measurement signal is based on the primary resonance frequency.

摘要： A droplet of fluid having a predetermined drop weight is ejected from a microfluidic channel. Electrical signals are received from a sensor in the microfluidic channel, wherein the electrical signals vary in response to the ejection of the droplet of fluid. The electrical signals of the sensor are calibrated to a rate of flow of fluid through the microfluidic channel based on a number of droplets ejected and the predetermined drop weight of each droplet.

摘要： The invention relates to an air mass meter with a sensor element, wherein an air mass flow to be measured moves across the sensor element and wherein the sensor element is formed as a micro-electro-mechanical system having a membrane, on which a heating element is formed. An electrical measuring resistor and at least two electrical comparison resistors are arranged upstream and downstream of the heating element in the direction of the air mass flow, and a first temperature sensor element and a second temperature sensor are formed by the electrical connection of a respective measuring resistor to at least two comparison resistors. In order to eliminate distortion of the measuring results due to contamination of the sensor element, or at least to keep the distortion within narrow limits, the first temperature sensor element is formed as a series circuit of resistors on the sensor element, with a measuring resistor arranged upstream of the heating element relative to the air mass flow and two comparison resistors arranged downstream of the heating element relative to the air mass flow, and the second temperature sensor element is formed as a series circuit of resistors on the sensor element, with a measuring resistor arranged downstream of the heating element relative to the air mass flow and two comparison resistors arranged upstream of the heating element relative to the air mass flow.
