FIELD: system measuring level of oil products. SUBSTANCE: proposed device has acoustic line made from magnetostrictive material with damper on one end, reading coil mounted in front of damper and connected to amplifier-former, three permanent magnets, one being fixed at end of acoustic line on side of reading coil and two others are put on floats of different buoyancy, two connected to different ends of acoustic line and linked to common bus. Acoustic line is connected at point located between fixed magnet and reading coil to power supply source and via first key - to measurement channel which includes register with parallel input and series shift of information, generator of counting pulses, counter, storage register, two formers of initiating pulses, address decoder, former of readiness signal, former of blocking signals and exchange bus. EFFECT: enhanced operational efficiency and authenticity. 1 dwg
