FIELD: engineering of devices for measuring level of liquid using ultrasound waves.
SUBSTANCE: level meter contains pressurized tube 1, ultrasound transformer 2 mounted at the end of wave duct 3, float 4 with constant magnet 5, measuring winding 6, generator 7, amplifiers 8, 9, impulse generator 10, key 11, constant voltage stabilizer 12, communication line 14, resistors 13, 15, direct current voltage source 16, solving block 17, transformer 18 and capacitor 19. as communication line coaxial wire may be used in level meter, by means of which powering of elements and transmission of information signals are organized, providing an advantage when using device to create multi-channel systems for controlling levels of liquid products.
EFFECT: simplified construction, increased reliability of device and increased precision of measurements.
