Waa maxay labada nooc ee mitirka socodka ultrasonic?

Mitirka socodka ultrasonic waxaa ugu horreyn loo kala saaraa laba nooc oo waaweyn iyadoo lagu saleynayo mabaadi'da hawlgalka:

1. Mitirka Socodka Ultrasonic-ka ee Waqtiga-Transit-Time
• Sida ay u Shaqeeyaan:
• Cabbir farqiga waqtiga safarka ee calaamadaha ultrasonic-ka ee u dhexeeya laba transducers:
• Hoos u socodka (iyadoo socodka uu socdo): Calaamaduhu si dhakhso ah ayay u socdaan.
• Kor u socodka (ka soo horjeeda socodka): Calaamaduhu waxay qaadataa waqti dheer.
• Farqiga waqtiyada socodka (\Delta t) wuxuu la mid yahay xawaaraha socodka dareeraha.
• Astaamaha Muhiimka ah:
• Waxa ugu fiican dareerayaasha nadiifka ah ama ku dhawaad ​​​​nadiif ah (tusaale ahaan, biyo, saliido, ama dareerayaasha aan nuugnayn).
• Aad u sax ah (±0.5% ilaa ±2.0% xaaladaha ku habboon).
• Ma aha mid duullaan ah oo si ballaaran loogu isticmaalo warshado kala duwan.
• Faa'iidooyinka:
• Si fiican ayuu ula shaqeeyaa dareerayaasha isku midka ah.
• Ku habboon cabbirro iyo agabyo badan oo tuubooyin ah.
• Rakibaadaha la qaadi karo ama kuwa joogtada ah ayaa diyaar ah.
• Xaddidaadaha:
• Saxnaanta ayaa yaraata marka dareerayaasha ay ku jiraan heerar sare oo walxo ah, xumbo, ama wasakh.

2. Mitirka Socodka Ultrasonic Doppler
• Sida ay u Shaqeeyaan:
• Cabbir isbeddelka soo noqnoqda (saamaynta Doppler) ee calaamadaha ultrasonic-ka ee ka tarjumaya walxaha ama xumbo ku jira dareeraha.
• Farqiga u dhexeeya calaamadaha la gudbiyo iyo kuwa la milicsado ayaa loo isticmaalaa in lagu xisaabiyo xawaaraha socodka.
• Astaamaha Muhiimka ah:
• Loogu talagalay dareerayaasha leh walxo ama xumbo laalaaban (tusaale ahaan, biyaha wasakhda ah, kuwa wasakhda ah, ama dareerayaasha wasakhda ah).
• Saxnaanta ayaa caadi ahaan ka hooseysa mitirrada waqtiga-socodka (±1.0% ilaa ±5.0%).
• Faa'iidooyinka:
• Waxay cabbiri kartaa socodka dareeraha aan muuqan ama wejiyo badan leh.
• Ku habboon codsiyada warshadaha iyo biyaha wasakhda ah.
• Xaddidaadaha:
• Waxay u baahan tahay ugu yaraan isku-urursiga walxaha ama xumbo (badanaa >100 ppm).
• Kuma habboona dareerayaasha nadiifka ah.

Labadan nooc waxay u adeegaan adeegyo kala duwan, iyadoo mitirada waqtiga-gudbinta ay ku fiican yihiin saxnaanta dareerayaasha nadiifka ah iyo mitirada Doppler-ka oo ku habboon socodka marxaladaha adag ama isku dhafan.
