| Abstract: | To improve concrete quality, proportion is very important,including precise measurement of sand is one of the key factors. Uhrasonic wave measurement system is proposed and designed for sand level;in order to ensure precision of measurement, automatic gain control circuit is adopted and temperature is compensated. This method is proved to be convenient and feasible by experiment, so a new reference method for sand quality measurement is |
