Ultrasonic level gauges basa rinobva pane ultrasonic tekinoroji uye nguva-ye-ndege kuyerwa misimboti.Heino mhedziso yemashandiro ayo:
Ultrasonic Pulse Generation: Iyo yemvura level gauge inoburitsa ultrasonic pulses kubva kune transducer kana sensor yakaiswa pane yemvura mudziyo kana pamusoro pemudziyo.Iyo transducer inoshandura simba remagetsi kuita masaisai e ultrasound, anofamba achidzika nemhepo kana gasi pamusoro pemvura.
Liquid surface reflection: Kana ma ultrasonic pulses asvika pamvura, iwo anoratidzwa zvishoma kumashure kune transducer nekuda kwemutsauko weacoustic impedance pakati pemhepo nemvura.Iyo nguva inotora kuti inoratidzwa pulse idzokere kune sensor yakanangana nechekure ye sensor kubva pamvura yemvura.
Nguva Yekuyereswa Kwendege: Iyo nhanho mita inoyera nguva inotora kuti ultrasonic pulse ifambe kubva ku sensor kuenda kune yemvura pamusoro uye kumashure.Nekushandisa kumhanya kunozivikanwa kweruzha mumhepo (kana zvimwewo midhiya) uye yakayerwa nguva yekubhururuka, chiyero chechiyero chemvura chinoverengera chinhambwe kusvika pamusoro pemvura.
Nhamba Yekuverengera: Kana chinhambwe chemvura chikatemwa, chiyero chegeji chinoshandisa ruzivo urwu kuverenga huwandu hwemvura mumudziyo kana mudziyo.Nekuziva iyo geometry yemudziyo, chiyero chegeji chinogona kunyatsoona nhanho zvichienderana nenhambwe yakayerwa.
Kubuda uye kuratidzwa: Ruzivo rwedanho rakaverengerwa rinowanzo kubuda sechiratidzo cheanalogi, dhijitari yekutaurirana protocol (yakadai se4-20 mA kana Modbus), kana inoratidzwa pane yemuno interface, ichibvumira mushandisi kutarisa uye kudzora mwero muchikepe.
Pakazere, ultrasonic level gauges inopa isiri-yekubata, yakavimbika, uye yakaringana kuyerwa kweyero yemvura mumhando dzakasiyana siyana dzeindasitiri nekutengesa.Iwo akakodzera kushandiswa mumatangi, silos, matsime uye mamwe emvura ekuchengetedza uye kugadzirisa masisitimu.
