Supply 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...

Algorithm to optimize transient hot-wire thermal property measurement.

The transient hot-wire method has been widely used to measure the thermal conductivity of fluids. The ideal working equation is based on the solution of the transient heat conduction equation for an infinite linear heat source assuming no natural convection or thermal end effects. In practice, the assumptions inherent in the model are only valid for a portion of the measurement time. In this st...

Design of High Voltage Low Power Supply Device

The objectives of this paper are to investigate and develop a device that will produce high voltage low power supply. Generation of high voltage low power supply can be determined by using Flyback converter as an optimum method which can improve the design of the device to make it smaller in size, simpler and cost effective. In this paper, the device circuits are simulated using PSPICE software...

Micromachined Hot-wire Boundary Layer Flow Imaging Array

Boundary layer flow imaging can provide real time information for flight control of air vehicles, and collision avoidance and stealth detection of underwater vehicles. High density, microscaled sensor arrays based on microfabrication techniques have made it possible to enable these new applications. We report on the development of such a flow sensor array. It is realized by combining surface mi...

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...
