【Abstract】 The principle of ultrasonic pulse reflection and measurement technique for thickness of concrete material is discussed. The optimum parameter is then designed for thickness detecting of concrete material. Ultrasonic detecting circuit and method were put forward. The results of practical measurement and ultrasonic detecting in two different thickness samples are compared. Experimental results show that the method is effective.更多还原
