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

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

SUBSTANCE: the level meter has a body 1, a directional tube 2 out of non-magnetic material, a float-level element 3 with a constant magnet 4, a limiter of transferring 5, a working medium 6, U-shaped acoustic line 7, an input and output signal electric acoustic transformers 8,9, a recording generator 10, a reading amplifier 11, a calculation block 12, an indication block 13 and a control bus-bar. At submerging of the body 1 of the level meter into the working medium the position of the float-level element 3 with the constant magnet 4 changes relatively to the U-shaped acoustic line 7. This is reflected on the positions in the time field of information signals excited and read by the input and output electric acoustic transformers 8,9 in the medium of the acoustic line 7, and also on the result of the digital coding level h_x fulfilled by the indication block 13 in the shape of light (sound) information.

EFFECT: increases reliability of the measuring level of transformation and explosion safety at the work with liquid medium, increases noise immunity and expands the field of technical usage.
