Abstract
In a pulse-echo measuring system, echo signals are compared by a difference calculator with the output of a model simulating the system. The detected differences are used to re-calculate parameters in the model. Other parameters are directly measured and applied to the model. A primary measurement, such as level, is detected more accurately and other parameters such as froth height and turbulence are estimated accurately.
