In a process for the determine ton of a volume flow a fluid is passed through a measuring line with a defined cross-section. In the measuring line the flow rate and the fill degree of the measuring line are determined and the volume flow is determined from the flow rate, the measuring line cross-section and fill degree. The determination of the flow rate and the fill degree takes place with a single measuring chamber at the same time and at the same location with respect to the axial extension of the measuring line.

Method and apparatus for determining a volume flow

The invention relates to a sensor system for determining the moisture content in a gas to be measured. On the basis of two current saturation ranges during the determination of the moisture content with the aid of a zirconia sensor, according to the invention two spatially separated sensors are provided, which are operated at different voltages corresponding to the individual saturation current ranges. By further evaluation of the signals, this permits a very precise, on-line determination of the moisture content of the gas to be measured.

Sensor system

The invention concerns a reading head with a tapered reading opening and/or a tapered reading stylus for reading bar-type, especially passive magnetic information on a data carrier. A high resolution in reading this information with a high output signal is obtained by tapering the reading opening in direction of the end face of the reading head. The reading head is located in a casing pot and has at least one field plate sensor, on which side remote from the face a permanent magnet is placed with a magnetic shunt to the casing pot.

An infrared temperature sensor with a sensor element sensitive for infrared radiation and which generates an analog output signal, permits a speed-variable and resolution-variable infrared temperature measurement, in that at least one resolution-adjustable converter means is provided for converting the analog signal into a digital signal and in that a digital signal processing means is provided for the program-controlled linearization and evaluation of the digital signal.
