Acoustic flowmeter for non-invasive determination of the flow or the flow rate in media flowing through electrically conductive objects, in particular pipes or pipelines, with a transmitting transducer for generating at least one ultrasonic wave in the object, which at a side facing the medium ...
Post-processing of 4D Flow CMR should always include correction for phase offsets and noise masking. Anti-aliasing needs to be performed if aliasing is present in regions of interest. Segmentation can be performed for the whole vessel in 3D or on 2D vessel cross-sections perpendicular to the c...
Measurement of flow rate and volume void fraction by means of a conventional meter plays an important role in the development of measurement techniques for multiphase flow parameters. Owing to its advantage in insensitivity to most physical properties of the fluid-like viscosity and density, a vortex...
Capacitative electromagnetic flow meter The invention consists in a capacitative electromagnetic flow meter in which excitation is performed at a frequency above the commercially available frequency and having a characteristic correction filter that corrects the gain frequency...

LUGB vortex flowmeter is mainly used for measuring the flow of industrial pipeline media fluid, such as gases, liquids, vapors and other media. ...
(Kulite Xcq-093) measuring the aerodynamic subglottal pressure \(P_s(t)\) relatively to ambient atmospheric pressure; a microphone (DPA 4060) calibrated by means of a sound level meter (Brüel & Kjaer 2250); and a high-speed camera (Mikrotron® MotionBLITZ EoSens® Cube7) to visualize...
Another advantage is the possibility to validate post-processing software and compare the results against flow meter, “timer and beaker” and pressure probe measurements, as well as other experimental fluid dynamics techniques, such as particle image velocimetry and direct pressure measurements [87, ...
VOxfilms were deposited on PI film substrates via reactive ion beam sputtering using a V target (99.9%) in an O2/Ar gas mixture. The sputtering pressure was set to 0.035 Pa. The partial pressure of oxygen (PaO2) was regulated using a mass flow meter. After deposition, the films were...
The length of straight pipe ≥ 40D for upstream and ≥5D for downstream if two 90°elbows on different planes in upstream(shown as Fig. 5). Flow or pressure control valve should be installed at least 5D far away from the meter in downstream as possible, if these valves must be installed...
