摘要： The invention provides an ultrasonic measuring cell for measuring the volume flow of a fluid flowing in a tube comprising a continuous central recess having a longitudinal extension so that the central recess can receive the fluid-carrying tube; at least six ultrasonic transducers; at least two inlay regions and optionally at least two ultrasonic interrupter regions. At least a first and a second ultrasonic transducer are positioned on a first side of the central recess and at least a third and a fourth ultrasonic transducer are positioned on a second side of the central recess wherein the first side and the second side are opposite to each other; and the first and the second ultrasonic transducer are aligned in a way that the first and/or the second ultrasonic transducer can emit a measuring signal oblique to the flow direction of a fluid in the tube.

摘要： Provided is an ultrasonic flow sensor with improved practicality. An ultrasonic wave is transmitted and received by an ultrasonic element. A first flow rate value of a fluid in a pipe is calculated based on a propagation time difference of an ultrasonic signal, a measurement value corresponding to an ultrasonic velocity, and a parameter for identifying an inner diameter of the pipe. A second flow rate value of the fluid in the pipe is calculated based on a frequency shift of the ultrasonic signal and the parameter. The first flow rate value is calculated using a propagation time of the ultrasonic signal as the measurement value in accordance with a correspondence relationship among a distance of a path through which the ultrasonic wave propagates through the fluid in the pipe, a time for which the ultrasonic signal propagates in the path, and the ultrasonic velocity.

摘要： A throughflow measurement system for measuring a fluid throughflow through a pipe includes a first measurement arrangement having at least two ultrasonic transducers and that is configured to determine a value for the fluid throughflow through the pipe on the basis of transit times of ultrasonic signals transmitted and received with and against the flow. A second measurement arrangement includes a plurality of hot-wire sensors that are arranged distributed over the cross-section of the pipe and that are each configured to determine a local flow value. An evaluation device is in signal connection with the first measurement arrangement and the second measurement arrangement and is configured to determine a flow profile on the basis of the local flow values determined by the hot-wire sensors and to modify the value for the fluid throughflow, which is determined by the first measurement arrangement, on the basis of the determined flow profile.
