Ultrasonic Flow Measurement with Integrated Temperature Measurement Compensation
Compensation for ultrasonic flow measurement has increasingly become the trend for applications that call for higher accuracy and tighter repeatability. Temperature is a variable that tends to have a significant impact on performance. Geometric dimension changes due to thermal expansion and contraction, as well as fluid dynamics, are impacted by temperature and thus have an influence on overall...
متن کاملTemperature compensation of ultrasonic velocity during the malolactic fermentation process
Ultrasonic properties of materials present a strong dependence on temperature and in turn the ultrasonic velocity of propagation in the material under test. It is precisely for this reason that most ultrasonic measurements are often carried out with thermostated samples by using either water tanks or climate chambers. This approach is viable in a laboratory and when the measured or characterize...
متن کاملsingle-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
15 صفحه اولSupply Voltage Compensation of Hot Wire Flow Measurement Device
Supply voltage compensation is important to keep the accuracy for hot wire/hot film gas flow sensors. A compensation experiment device is established, the two steps curve fitting is presented to determine the functional relations among flow、sensor output and supply voltage, the coefficient of fitting polynomial is determined by Least Square method, thus eliminating the influence of supply volta...
