Abstract
To improve concrete quality
proportion is very important
including precise measurement of sand is one of the key factors. Ultrasonic 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 provided.
