Methods of measuring ultrasonic pulse velocity

  1. Direct transmission

  2. Indirect transmission

  3. Surface transmission

Direct transmission- The transmitting and receiving transducers are placed on opposite surfaces of the concrete slab as shown in figure below.

Indirect transmission: The transmitting and receiving transducers are placed on opposite surfaces of the concrete slab. This will give maximum sensitivity and provide a well-defined path length as shown in figure below.

Surface transmission: The transmitting and receiving transducers are placed on same or either side of surfaces of the concrete slab as shown in figure below.
