New way of statistical pulsation measurements by radioisotope technique is described, being alternative to the existing stream control methods and allowing to improve accuracy of measurements. The basic formula fundamental for the method of calibration characteristics correction is shown.
The radioisotope method of specific weight measurement of the controlled environment is briefly described in article. The technique of creation and the block diagram of servo astatic system of the second order is submitted with the purpose of indemnification of errors due to influence on result of measurements of casual characteristics of a stream.
