Abstract

Aparatul potrivit inventiei are în compunere un detector de sens al variatiei de nivel sustinut si legat electric cu o banda-cablu cu gradatii echidistante, care moduleaza prin reflexie un fascicol al unui detector optoelectronic cu care se stabileste nivelul lichidului la un moment dat si viteza de variatie a nivelului, detectorul de sens fiind constituit dintr-un senzor conductometric sau capacitiv si un altul de tip ultrasonor, înglobate împreuna cu un montaj electronic continând un osiclator, doua amplificatoare si un discriminator care, fiind alimentat electric prin banda-cablu, transmite tot prin aceste semnale corespunzatoare pentru miscarea sondei pentru a urmari permanent suprafata de nivel al lichidului.The apparatus according to the invention consists of a sustained and electrically interconnected level detector with an equidistant gradation band which modulates by reflection a beam of an optoelectronic detector which determines the level of the liquid at a given moment and the velocity the sensing detector consists of a conductive or capacitive sensor and another of the ultrasonic type, embedded with an electronic assembly containing an oscillator, two amplifiers and a discriminator which, being electrically powered by the cable strip, transmits all through these appropriate signals for moving the probe to continuously pursue the liquid level.
