The contents of a container are non-intrusively monitored by probing the container with an ultrasonic signal, and measuring changes in the ultrasound signature of the received signal after the signal has passed through the contents of the container.

Monitoring the contents of a container by ultrasonic means

An arrangement for the measurement of the height of a layer of a first liquid floating on a second liquid which comprises projection means for projecting a beam of optical radiation along an inspection path which is horizontal when the arrangement is in use, detector means for detecting radiation of the said beam after transmission along the inspection path, means for providing relative displacement in a direction which is vertical when the arrangement is in use between the said layer and the said inspection path whereby the said layer traverses the inspection path, the detector means being capable of observing the upper and lower surfaces of the said layer by detecting changes in an optical transmission property of the said beam occurring at the said surfaces and means for measuring the said relative displacement between the locations of the observed upper and lower surfaces.
