Accuracy of Medical Oxygen Flowmeters: A Multicentric Field Study
《Health》2014年第15期1978-1983,共6页Frédéric Duprez Maria Barile Thierry Bonus Grégory Cuvelier Sandra Ollieuz Shahram Mashayekhi Alexandre Legrand 
The accuracy of 476 oxygen flowmeters was investigated using a thermal mass flowmeter in eight hospitals in France and Belgium. Different oxygen flow rates (2 to 15 l/min) were evaluated at the patient’s bed. When th...

Nonlinear Vibration Characteristics of Coriolis Mass Flowmeter被引量：3
《Chinese Journal of Aeronautics》2009年第2期198-205,共8页郑德智 王帅 樊尚春 
National High-tech Research and Development Pro-gram (2008AA042207)
Coriolis mass flowmeter (CMF) is generally regarded as a linear system when the vibration amplitude of the measuring tube is relatively small, but the spectrum of its output signals still show existence of some multip...

Design of the target type flowmeter based on fiber Bragg grating and experiment被引量：2
《Chinese Optics Letters》2008年第11期815-817,共3页乔学光 张倩 傅海威 禹大宽 
supported by the National"863"Project of China (No.2006AA06Z210 and 2007AA03Z413);the National Natural Science Foundation of China(No.60654001 and 60727004);and the Major Technological Innovation Program of Xi'an City of China(No.GG06004).
The target type flowmeter based on fiber Bragg gratings （FBGs） is experimentally studied. The relationship between the central wavelength shift of FBG and the flux is derived and the analytic expression is also give...

DESIGN,FABRICATION,TESTING AND MECHANICAL ANALYSIS OF BULK-MICROMACHINED FLOWMETERS
《Acta Mechanica Sinica》2004年第2期152-158,共7页王小保 钱劲 张大成 
The project supported by the National "973" Project (TG1999033108);the National Natural Science Foundation of China (19928205,50131160739 and 10072068)
Micromachined piezoresistive flowmeters with four different types of sensing struc- tures have been designed,fabricated and tested.Piezoresistors were defined at the end of the sensors through p-diffusion,and their va...

The Principle of Calibration Using the Ionic Current——A New Calibration Method for Electro-Magnetic Flowmeters
《Advances in Manufacturing》1998年第2期38-42,共5页Li Bin Sheng Yu (School of Automation) 
An equivalent relationship between electro magnetic flowmeters (EMFs) and the Hall effect is discussed in principle and three equivalent conclusions about their measuring equations are derived. Thereby,the calibratio...
