a model based transit time ultrasonic gas flowrate Measurement Method
Instrumentation and Measurement Technology Conference, 2016Co-Authors: Yandan Jiang, Baoliang Wang, Zhiyao HuangAbstract:Based on the transit-time ultrasonic gas flowrate Measurement principle, a new model-based time-of-flight (TOF) Measurement Method is proposed. The proposed TOF Measurement Method includes two parts, the signal preprocessing and the model-fitting. Zero-phase filtering and independent component analysis with reference (ICA-R) are used to realize the signal preprocessing. The least-squares algorithm is used to implement the model-fitting and hence to obtain the TOF. A new single-acoustic-path ultrasonic gas flowmeter prototype with the inner diameter of 100 mm is developed and experiments are carried out to test the performance of the prototype. Experimental results show that the proposed signal preprocessing can effectively correct the distorted/noise-polluted Measurement signal. In addition, the proposed model-based TOF Measurement Method is effective and can implement TOF Measurement with higher repeatability and low standard deviation. For the gas flowrate ranges from 5 to 50 $\text{m}^{3}$ /h, the repeatability error of gas flowrate Measurement is less than 1.99% and the maximum relative error of flowrate Measurement is less than 3.27%. For the gas flowrate ranges from 50 to 500 $\text{m}^{3}$ /h, the repeatability error of gas flowrate Measurement is less than 0.51% and the maximum relative error of flowrate Measurement is less than 1.43%.

Improving the lateral resolution of a multi-sensor profile Measurement Method by non-equidistant sensor spacing
Optics express, 2010Co-Authors: Axel Wiegmann, Michael Schulz, Clemens ElsterAbstract:We present a Method to enhance the achievable lateral resolution of a multi-sensor scanning profile Measurement Method. The relationship between the profile Measurement Method considered and established shearing techniques is illustrated. Simulation and Measurement results show that non-equidistant sensor spacing can improve the lateral resolution significantly.

Measurement Method of Synchronization Error for Wireless Sensor Networks
Computer Engineering, 2011Co-Authors: Xu Yong-junAbstract:Considering the difficulty in precise Measurement of time synchronization algorithm of wireless sensor networks,this paper proposes a Measurement Method with high precision and low cost by utilizing the capability of the "self interrupt",which is realized in many microcontrollers.The Measurement Method is realized on GAINS testbed.To verify its validity,the synchronization error of TPSN is measured on the testbed.Compared with the Measurement Method with logic analyzer,better precision and lower price are simultaneously gotten.
