Aerospace Instrument-Making Annotation << Back Survey of filling level measurement systems on rocket-carriers Blinov D.I. Borminskiy S.A. We should mention such disadvantages of present filling level measurement systems on rocket-carriers as low noise protection, considerable dependence of data bus from external events, limited length of data bus, and also poor accuracy of a capacitive method of level measurements in case of using it on new models of carrier rockets. Today wave liquids level measurement and control devices, based on directional electromagnetic radiation, are perspective. Author suggested the way of liquid level measuring, concluding in using of laser distancemeter. Key words: filling level measurement system, liquid level measurement devices, wave devices, laser distancemeter. Contacts: E-mail: SchumerBlin@yandex.ru Pp. 03-08.
