Abstract
This project describes an investigation of the use of light emitted diode and photodiode sensor in a correlative measurement of flowing solid particle velocity. The main purpose is to investigate the optical sensor capability to senses the moving particle in sensing area. This optical measurement circuit consists of sensor, signal conditioning circuit and data acquisition system. Sensors fixtures are designed based on parallel beam projection. To measure the velocity, cross correlation technique is used where eight pairs of sensor is mounted upstream and downstream of the pipe. Each pair of sensor is placed facing each other in parallel beam projection. Any object interfere the sensing area; conditional circuit will produce a signal in voltage form. The output from both sensors is cross correlated. Cross correlation is a process of comparing a signal with another signal by multiplication of the instantaneous value and taking the average. It is a function of the relative time between the signals. The transmit time obtained and the distance of upstream and downstream will be used to determine the velocity of the measurement before it be transferred by data acquisition (DAS) device into computer. The data is collected by using data acquisition system and it was an offline process. Then, the data obtained will be stored and compared into Microsoft ACCESS database. The final result of the velocity measurement will be measured and displayed by using Microsoft Visual Basic.
