FIELD: measuring engineering. SUBSTANCE: level indicator has a float with a ring magnet mounted on a nonmagnetic pipe. Magnet core is positioned within a pipe at level of the ring magnet. The magnet core can freely move along the pipe in accordance with float movements and changing of liquid level. Bottom end of a magnetic tape provided with records of digital data is connected with the magnet core. The top end of the magnet tape is positioned within a magnetic tape recorder whose output is connected to a micro-computer through a modem.
