The testing of spilled-oil recovery systems necessitates the measurement of the thickness of waterborne oil layers. The construction and testing of a successful electro-acoustic oil layer thickness gauge is described. The system determines oil layer thickness by measuring the time interval between acoustic signals reflected from the bottom and top of the layer. The major acoustic and electrical parameters of the systems are given and their effect on the accuracy of the system is discussed, when pertinent. Examples of thickness measurements reduced to graphic form by computer processing are included. With careful manual operation, layers down to 1 mm are measurable by the system. With automatic data processing, a minimum thickness threshold ...
