Mamita emvura eUltrasonic vs. Electromagnetic: Kuenzanisa Kwakazara

Nheyo dzeKushanda dzeCore

Mamita emvura eUltrasonic anoenderana nemusiyano wenguva yekufamba kana kuti Doppler effect. Mamodheru enguva yekufamba anotumira masaini eUltrasonic pamwe nekuyerera kwemvura; mukaha wenguva uripo pakati pemasaini aya unoyera kumhanya kwekuyerera kwemvura. Mamodheru eDoppler, zvakasiyana, anoona kuchinja kwemafrequency kubva kumafungu eUltrasonic achisvetuka kubva muzvidimbu mumvura, achishanda zvakanaka kunyangwe paine kuyerera kusina kugadzikana.​

Mamita emvura emagetsi anoshandisa Mutemo waFaraday weKupinza Masimba eMagetsi. Anogadzira simba remagineti rakafanana papombi. Kana mvura inoyerera ichipfuura nemumunda uyu, inogadzira simba remagetsi (EMF) mumaerekitirodhi—simba reEMF rinoenderana zvakananga nekumhanya kwekuyerera, zvichiita kuti kuyerwa kwacho kuve kwakarurama.​

Kusiyana Kwakakosha Kwekushanda​

Panyaya yekururamisa, ma electromagnetic meters anowanzova nemucheto mudiki: mazhinji anoramba akarurama ±0.2% kusvika ±0.5% pakati pema flow ranges, nepo ma ultrasonic models ari pakati pe ±0.5% (yekutengeserana) kusvika ±0.2% (yeindasitiri). Kuti flow range ikwanise kufamba, ma electromagnetic meters anopa turndown ratio inosvika 1:1000, achibata ultra-low uye high flows. Ma ultrasound meters anosvika 1:500, achiri akasimba asi asingashande zvakanyanya pakuyerera kwakanyanya.​

Kuenderana kwezviridzwa zvemagetsi ndicho chinhu chikuru chinosiyanisa. Mamita emagetsi anoshanda nezvinwiwa zvinofambisa mhepo uye zvisingafambise mhepo (semuenzaniso, mvura yakachena, makemikari), zvichiita kuti zvive zvakanaka kumaindasitiri akadai semishonga. Mamita emagetsi anoda mvura ine simba rekufambisa mhepo ≥5 μS/cm — anokundikana nemvura yakachena kana mafuta.​

Zvinodiwa pakuiswa zvinosiyanawo. Mamita emagetsi anotenderera panguva yekufamba anoda dhayamita 5-10 dzemapaipi akatwasuka kumusoro/kudzika kuti afambe zvakanaka, nepo maDoppler models achichinjika zviri nyore. Mamita emagetsi anongoda dhayamita 3-5 dzakatwasuka chete, uye maelectrode awo anotsvedza anodzivirira kukanganiswa kwekuyerera.​

Zvakanakira uye Zvipingamupinyi​

Mamita eUltrasonic anopenya zvikuru: ma "clamp-on" anoiswa kunze, hapana kudiwa kwekugadzirisa pombi—akanakira kugadziriswazve. Haanawo kugadziriswa kwakawanda, pasina zvikamu zvinofamba zvinobata mvura. Zvisinei, kusviba kwakanyanya kana mabubble emhepo zvinogona kukanganisa kururama, uye mamodheru emhando yepamusoro anodhura zvakanyanya.​

Ma electromagnetic meter anobudirira mumamiriro ezvinhu akaomarara: ma electrodes anodzivirira ngura (tantalum, platinum-iridium) anobata mvura yakasviba nemvura ine sediment yakawanda. Anobatanidzwa zviri nyore neIoT systems kuti ionekwe panguva chaiyo. Asi kuenderana kwavo ne conductivity kunoderedza kushandiswa, uye mazhinji anoda simba rekunze - hazvina kunaka kunzvimbo dziri kure.​

Maitiro Akakodzera Ekushandisa​

Mamita emagetsi ekugadzira akakodzera dzimba dzekugara/dzemabhizimisi (dhayamita diki, mvura yepombi), masisitimu emvura yakachena (mishonga, marabhoritari), uye kugadzirisa mapaipi ekare. Anokodzerawo mapaipi makuru emakanzuru kana emaindasitiri.​

Mamita emagetsi anobatsira zvikuru pakudzora mashandiro emaindasitiri (makemikari, nzvimbo dzemvura yakasviba), kuparadzirwa kwemvura yemumaguta (kuona kudonha kwemvura), nzvimbo dzekutengeserana (kushandiswa kwemvura yakasanganiswa), uye kudiridza kwekurima (pasi pevhu rinofambisa mvura).

Mhedziso​

Mamita ese ari maviri akagadzirwa zvakanaka, asi simba rawo rinotungamira kusarudzwa. Sarudza ultrasonic yemidziyo isingafambise mvura kana yekugadzirisa magetsi; electromagnetic yekururama kwakanyanya ine michina inofamba kana nzvimbo dzakaoma. Kunzwisisa misiyano iyi kunoita kuti mvura ikwanise kuyerwa zvakanaka, kungave kwekubhadharisa, kudzora maindasitiri, kana manejimendi yemaguta.​
