MAGNETOSTRICTIVE LEVEL METER-INDICATOR Russian patent published in 2007 - IPC G01F23/28 G01F23/30 

FIELD: the invention refers to measuring and transformational technique and is designed for using in quality of a mobile measuring device for measuring and control of liquid highly explosive medium.

SUBSTANCE: the level meter has a body 1, a directional tube 2 out of non-magnetic material, a magnetostrictive acoustic line 3 with a wave reflector 4 and a stabilizer 5 of tension and twisting placed in a discrete filler 6 with small surface friction, an input and output signal electroacoustic transformers 7,8, a float-level element 9 with a constant magnet 10, a limiter 11 of transferring, a working medium 12, a recording generator 13, a reading amplifier 14, a calculation block 15, an indication block 16 and a control bus-bar 17. The changing of the level of liquid 12 in a working cavity of the bode 1 of the arrangement call transferring of the float-level element 9 with a magnet 10 relatively to the acoustic line 3. This reflects dimension of a time interval of the level formed along the acoustic section of the primary transformer with the aid of the recording generator 13 and the reading amplifier 14 which transforms with the aid of the calculation block 15 into a binary code and is reflected by the indication block 16. The technical result is increasing of reliability of the measuring transformation of the level and expansion of technical application.

EFFECT: increases noise immunity and explosion safety of the measuring transformation of the level.
