Hasi hari isesengura rirambuye ry'ihame ryabyo ry'imikorere, ibyiza by'ingenzi, uburyo butandukanye bwo gukoresha, n'ibyo bigomba kwitabwaho kugira ngo bikoreshwe neza.
I. Ihame ry'imikorere: Gukoresha imiraba y'amajwi kugira ngo upime neza
Mu mizi y'imikorere y'urwego rwa ultrasound ni uburyo bworoshye ariko bufite akamaro bushingiye ku ihame ry' "igihe cyo kuguruka" ry'amajwi. Igikoresho gisanzwe kigizwe n'ibice bitatu by'ingenzi: transducer (ikora nk'itumanaho n'iyakira amajwi ya ultrasound), igikoresho gitunganya ibimenyetso, hamwe n'uburyo bwo kwerekana cyangwa gusohora.
Iyi gahunda itangira iyo transducer isohoye urumuri rw’imiraba ya ultrasonic ku buso bw’umwuka (amazi, ifu, granular solid, cyangwa slurry) aho urwego rwayo rugomba gupimwa. Uko iyo miraba inyura mu kirere (cyangwa gaze) hejuru y’umwuka, ihura n’ubuso bw’umwuka hanyuma ikongera ikagaruka nk’ibimenyetso by’impinduka. Hanyuma transducer imenya ayo majwi yagaragaye hanyuma yohereza ikimenyetso ku gice gitunganya. Igice gitunganya gipima igihe gishize hagati yo gusohora kw’umuraba w’umwimerere no kwakira impinduka—iki ni cyo “gihe cyo kuguruka.”
Kubera ko umuvuduko w'amajwi muri gaze runaka (urugero, umwuka) ari ikintu kizwi (gishobora guhindurwa bitewe n'ibintu nk'ubushyuhe, umuvuduko, n'ubushuhe), igikoresho gitunganya gikoresha formula intera = (umuvuduko w'amajwi × igihe cyo kuguruka) / 2 (igabanyijwemo 2 kuko umuraba ujya mu cyuma gipima no gusubira inyuma) kugira ngo hamenyekane intera iri hagati y'icyuma gipima n'ubuso bw'icyuma. Mu gukuramo iyi ntera yapimwe uhereye ku burebure bwose bwa tanki cyangwa ubwato, icyuma gipima kibara urwego nyarwo rw'icyuma. Aya makuru agaragara kuri ecran y'igikoresho cyangwa yohererezwa nk'ikimenyetso gisanzwe cy'amashanyarazi (nka 4–20 mA, RS485, cyangwa Modbus) kugira ngo ahuzwe na sisitemu zo kugenzura, platformi za SCADA, cyangwa ibikoresho byo kugenzura bishingiye ku bicu. Ubu buryo bwo kudahuza bukuraho gukenera imikoranire ifatika n'icyuma gipima, ikintu gishingira ku nyungu nyinshi z'ingenzi z'ikoranabuhanga.
II. Ibyiza by'ingenzi: Impamvu ibipimo by'urwego rwa Ultrasonic bigaragarira
