摘要： A fluid flow meter serves to determine the flow of a fluid, in particular in the form of gas, in a pipe, wherein the fluid flow meter is configured to generate a first measurement variable and at least a second measurement variable for the fluid and at least a first diagnostic parameter. The fluid flow meter comprises a diagnostic system that is configured to determine a first threshold value for the at least one first diagnostic parameter both based on the first measurement variable and based on the at least one second measurement variable and to output a first message to a higher-ranking control device when said first threshold value is reached.

摘要： A method for determining multi-phase flow properties of a fluid is disclosed. The method includes measuring a first time for a first ultrasonic signal to be emitted from a first transducer into the fluid, reflected off an inner surface of the pipeline, and received back at the first transducer. Measuring a second time for the first ultrasonic signal to be emitted from the first transducer into the fluid and received at a second transducer. Calculating, using the first time and the second time, at least one of: a liquid to gas ratio, a fluid density, a gas holdup, a liquid holdup, and a fluid velocity of the fluid flowing through the pipeline.

摘要： The physical quantity measurement device includes a secondary flow path disposed outside a multilayer unit and configured to connect an upstream opening to a downstream opening. The secondary flow path is disposed gravitationally below a primary flow path. Ultrasonic transceivers are disposed to project into a flow in the multilayer unit. In the thus-configured physical quantity measurement device, the entry of water droplets into an ultrasonic propagation path and the adhesion of water droplets to the ultrasonic transceivers are substantially prevented, so that, even when the fluid flowing in contains water droplets, the physical quantity measurement device can measure the flow rate of the fluid and the concentration of components contained in the fluid.

摘要： A method of measuring the speed of a fluid, comprising the successive steps of: causing the processor component to emit at the same emission time both a first electrical excitation signal that is applied as input to a first transducer and also a second electrical excitation signal that is applied as input to a second transducer, such that the first transducer generates a first ultrasonic signal and such that the second transducer generates a second ultrasonic signal; putting the processor component on standby; reactivating the processor component after a predetermined standby duration; causing the first ultrasonic signal to be acquired by the second transducer and then by the processor component, and causing the second ultrasonic signal to be acquired by the first transducer and then by the processor component; using a value DToF to estimate the speed of the fluid.

摘要： A method of measuring temperature and velocity of a fluid flow passing through a device of a plant includes the step of positioning at least two sensors in the device. For each sensor, a traveling path for an acoustic signal received from another sensor is determined. Each sensor emits an acoustic signal at a frequency that differs from a frequency of an acoustic signal to be emitted by the other sensor(s) in the fluid flow. A velocity profile and temperature profile for the fluid flow based on the acoustic signals received by the sensors is determined. A measurement system can include sensors and a computer device that can determine a velocity profile and temperature profile for a fluid flow passing through a device based on the acoustic signals received by the sensors. A plant can be configured to implement the method or include an embodiment of the measurement system.

摘要： A flow meter ultrasonically measures fluid velocity in a pipe. Ultrasonic signals received by ultrasonic transducers are digitized. The difference between two ultrasonic propagation times is determined by computing a discrete cross-correlation of the digitized received signals. Computation time is reduced by computing only a few cross-correlation values near a peak cross-correlation value.

摘要： A disposable conduit 1 includes piezo-electric elements 2a and 2b and a memory chip 10 in which calibration data specific to the relevant conduit is stored. Before measurement, a non-disposable electrical measuring circuit reads the calibration data out of the memory chip 10 to prepare a calibrating equation or a calibration table. A flow speed of a blood passing through the conduit or a flow rate calculated from the flow speed is corrected in accordance with the calibrating equation or calibration table.

摘要： A method for recognizing the presence of liquid (30) in a gas flow flowing in a pipeline uses an ultrasound flowmeter (10). Measurement paths are provided in pairs which are displaced vertically by an equal predefined distance with respect to the center axis such that one lies in an upper region above the center axis and one lies beneath the center axis. A check is made in three stages to define various measurement values, turbulence values and speed of sound values. A liquid warning signal is output when an invalid measurement value is delivered in the first stage, or when the ratio of the turbulence values in the second stage differs from 1 by more than a predefined tolerance value, or when the ratio of the speeds of sound in the third stage differs from 1 by more than a predefined tolerance ratio.

摘要： In a method for determining the flow rate of fluids using the ultrasonic transit time method, the flow speed and therefrom the flow rate of the fluid is determined from the transit time of ultrasound signals through the measurement section. In order to take into account the change in the transmission function of the ultrasonic converters, which change acts as a drift of the measurement variable, the transmission function of the measurement section is determined at least approximately, and at least one ultrasonic transit time is corrected by means of a correction value that is determined from the group transit time of the transmission function.
