Abstract

Inventia se refera la un debitmetru cu imersor destinat masurarii debitelor de lichide si gaze si indicarii, atât local, printr-o valoare instantanee, cât si la distanta, prin transmiterea unui semnal electric. Debitmetrul cu imersor este alcatuit dintr-o carcasa cilindrica prevazuta cu niste racorduri si cu o diafragma în care culiseaza un imersor tronconic. Rotatia unui arbore, la capatul caruia este fixat un ac indicator, este transformata într-un semnal electric prin intermediul unor traductoare inductive, iar prelucrarea semnalului electric obtinut se face cu un bloc electronic alcatuit dintr-un oscilator cuplat la un generator, o sursa de tensiune stabilizata si niste amplificatoare. Debitmetrul, conform inventiei, este prevazut cu unimersor (B), dotat la partea inferioara cu un disc (6), iar la partea superioara cu o rozeta (7), montata la capatul unei tije (8), ce ghideaza într-o bucsa (9). Pe aceeasi tija (8) este rigidizata o cremaliera magnetica (C), alcatuita dintr-un supo rt (10), pe care sunt montate alternativ niste pastile magnetice (11), ce interactioneaza cu niste dinti (a) ai unei roti dintate (13), montata pe un arbore (12). Pe arborele (12) mai sunt montate o elice (14) si o cama (16 sau 20), ce actioneaza unul din traductoarele inductive (D sau E) cunoscute.The invention relates to an immersion flowmeter for measuring liquid and gas flows and indications, both locally, at an instantaneous value and at a distance, by transmitting an electrical signal. The immersion meter is made up of a cylindrical casing provided with some connections and a diaphragm in which a tronconic dipper slides. The rotation of a shaft at the end of which is fixed to an indicator needle is transformed into an electrical signal by means of inductive transducers and the processing of the electrical signal is made with an electronic block made up of an oscillator coupled to a generator, stabilized voltage and some amplifiers. According to the invention, the flowmeter is provided with a bimmer (B) provided at the bottom with a disc (6) and at the top with a rosette (7) mounted at the end of a rod (8) guiding in a bush (9). On the same rod (8) there is rigidized a magnetic rack (C), consisting of a rat supporter (10), on which are alternatively mounted magnetic pads (11), which interact with some teeth (a) of a toothed wheel 13) mounted on a shaft (12). A propeller (14) and a cam (16 or 20) are also mounted on the shaft (12) acting on one of the known inductance transducers (D or E).
