Способ ультразвукового измерения уровня жидкости путем измерения времени прохождения акустического ультразвукового импульса по металлическому стержню, установленному вертикально внутри емкости, от излучателя до приемника, отличающийся тем, что акустический сигнал возбуждают пьезокерамическим излучателем, размещенным внутри плавающего на поверхности жидкости поплавка, коаксиально охватывающего звукопровод-металлический стержень. по которому протекает переменный электрический ток, обеспечивающий индукционное питание и синхронизацию излучателя.A method of ultrasonic measurement of a liquid level by measuring the time it takes for an acoustic ultrasonic pulse to travel through a metal rod mounted vertically inside the vessel, from the emitter to the receiver, characterized in that the acoustic signal is excited by a piezoceramic emitter located inside a float floating on the liquid surface that coaxially surrounds the sound pipe-metal rod . through which an alternating electric current flows, providing induction power and emitter synchronization.
