Abstract: new method of measuring the volume of flow in a producing oil well according to the inter-coherent detection theory is presented in this paper. The principle of the new method, the design of sensing units, the process of signal management. and the ways, steps and programing of digital intercoherent management with a microcomputer are mainly introuced here.

Key words: Inter-coherent function, Digital Inter-coherent Management, Time-lag zone
