This paper introduces the application of the method of object oriented analysis and design in software system of new-style microcomputer nuclear gauge and control system, which we developed recently.

This paper describes the design of a kind nuclear gauge union function instructional meter, for experiments with three types of nuclear gauge-including level gauge, density gauge and thickness gauge.

In order to reduce radiation on the operator, a remote-control nuclear surface moisture-density gauge is developed by improving the original nuclear surface moisture-density gauge.
