<p>A method and apparatus for determining of weight on a strucutre which utilizes an acoustic wave transmitting tranducer (30) and an acoustic wave receiving transducer (32). The elapsed time of transmission of the acoustic wave between the transmitting transducer and the receiving transducer varies according to the amount of weight on the load bearing member within the structure upon which the transducers are fixedly mounted. By determining of the elapsed time and comparing same in computer (58) to a known weight versus elapsed time curve, the current weight can be determined for the structure.</p> |
