摘要

The invention provides an improved instrumentation system for measurement of velocity of solid particles in a two-phase gas-solid flow through a pneumatic conveyor, comprising (i) tv/o sensors fitted at an adjustable distance from each other along the length of a tube of an electrical non-conducting material, used for conveying a mixture of a gas and solid particles at a given flow rate; (ii) two electronic amplifiers for amplifying the fluctuations in the electrostatic charge collected on said solid particles and picked by said tv/o sensors; (iii) an analog to digital (A/D) converter for converting the analog voltage output of each said electronic amplifier into corresponding 12-bit digital data; and (iv) a 406 based personal computer (PC) which is provided with a software programmed in C language, for calculating and displaying the velocity of the said solid particles flowing through said tube from the cross correlation function of the outputs of said two electronic amplifiers. The said sensors are of electrodynamic 'ring' or 'horn' types and the said electronic amplifiers are operational amplifiers of relatively simple design and construction, each having an integrated circuit and a low-pass filter.
