Ma Radar level meter ndi ma ultrasonic level meter onse ndi ukadaulo wotchuka womwe umagwiritsidwa ntchito poyesa kuchuluka kwa zinthu (zamadzimadzi kapena zolimba) m'matangi, m'ziwiya, kapena m'malo otseguka, koma amagwira ntchito motsatira mfundo zosiyanasiyana ndipo ali ndi zabwino ndi zovuta zosiyana. Nayi kufananiza pakati pa ziwirizi:
1. Mfundo Yogwirira Ntchito:
Chiyeso cha Radar Level:
Ma Radar level meters amagwiritsa ntchito ma microwave radar signals (nthawi zambiri mu GHz frequency range) kuti ayesere mtunda wopita pamwamba pa chinthucho. Ma microwave amenewa amatuluka kuchokera ku sensa, amadumphadumpha pamwamba, ndikubwerera ku sensa. Nthawi yomwe mafunde a radar amatenga kuti afike pamwamba ndi kumbuyo imagwiritsidwa ntchito kuwerengera mulingo wa chinthucho.
Chiyeso cha Mulingo wa Ultrasonic:
Ma ultrasound level meters amagwira ntchito potulutsa mafunde amphamvu kwambiri (mafunde a ultrasonic) kuchokera ku sensa. Mafunde awa amayenda mumlengalenga, amagunda pamwamba pa chinthucho, kenako amabwereranso ku sensa. Poyesa nthawi yomwe mafunde a mawu amabweranso, makinawo amawerengera mtunda wopita pamwamba pa chinthucho.
2. Mtundu wa Ntchito:
Chiyeso cha Radar Level:
Ingagwiritsidwe ntchito poyesa mulingo wamadzimadzi komanso wolimba.
Imagwira ntchito bwino m'malo otentha kwambiri, opanikizika kwambiri, kapena m'malo opanda mpweya.
Imagwira ntchito bwino m'zombo zomwe zili ndi thovu, nthunzi, kapena fumbi m'chilengedwe.
Ikhoza kuyeza milingo yayitali kwambiri (malo osungiramo zinthu zazitali kapena matanki).
Chiyeso cha Mulingo wa Ultrasonic:
Amagwiritsidwa ntchito makamaka poyesa mulingo wamadzimadzi, ngakhale kuti masensa ena a ultrasound amatha kusinthidwa kuti agwirizane ndi zinthu zolimba.
Magwiridwe antchito amakhudzidwa kwambiri ndi zinthu zachilengedwe monga kutentha, kuthamanga, nthunzi, fumbi, ndi thovu.
Zochepa pa kutentha ndi kuthamanga kwa mpweya poyerekeza ndi ma radar mita.
3. Kulondola ndi Kulondola:
Chiyeso cha Radar Level:
Kulondola kwambiri komanso kulondola kwambiri, makamaka m'malo ovuta.
Sizingatengeke kwambiri ndi kusintha kwa zinthu zomwe zimayesedwa (monga kusintha kwa kutentha, nthunzi, thovu, kapena fumbi).
Chiyeso cha Mulingo wa Ultrasonic:
Kulondola kungakhudzidwe ndi kusintha kwa kutentha, chinyezi, ndi mtundu wa chinthu chogwiritsidwa ntchito (monga nthunzi, thovu, kapena fumbi).
Mwina sizingakhale zolondola ngati zoyezera radar m'mikhalidwe yovuta kapena yovuta.
4. Kusamala zachilengedwe:
Chiyeso cha Radar Level:
Mafunde a radar sakhudzidwa ndi kusintha kwa kutentha, kuthamanga, chinyezi, ndi nthunzi.
Ikhoza kugwira ntchito m'mikhalidwe yovuta kwambiri (monga kutentha kwambiri, vacuum, kuthamanga kwambiri, kapena pamene pali mpweya kapena nthunzi).
Chiyeso cha Mulingo wa Ultrasonic:
Imakhala yogwirizana ndi kutentha, chinyezi, ndi kusintha kwa kuthamanga kwa mpweya, zomwe zingakhudze liwiro la mawu.
Sizigwira ntchito bwino m'malo okhala ndi nthunzi yambiri, thovu, fumbi, kapena kugwedezeka.
5. Mtengo:
Chiyeso cha Radar Level:
Kawirikawiri zimakhala zodula kuposa zoyezera ma ultrasound level, makamaka pa zitsanzo zolondola kwambiri kapena zogwira ntchito kwambiri.
Mtengo umakwera ndi zinthu zapamwamba monga radar ya pafupipafupi, kuthekera kotentha kwambiri, ndi zina zotero.
Chiyeso cha Mulingo wa Ultrasonic:**
Kawirikawiri zimakhala zotsika mtengo komanso zotsika mtengo pa ntchito zoyezera zapadziko lonse.
Chisankho chabwino pa ntchito zosavuta komanso zosafuna zambiri pomwe nyengo ndi yokhazikika.
6. Kukonza:
Chiyeso cha Radar Level:
Sizimafunika kukonza kwambiri chifukwa palibe zinthu zosuntha.
Kawirikawiri zimakhala zolimba kwambiri m'malo ovuta, koma zimakhala zovuta kuziyika ndikuzikonza.
Chiyeso cha Mulingo wa Ultrasonic:
Zimafunikanso kusamalidwa pang'ono, koma zimakhala zovuta kwambiri ku zinthu zakunja (monga fumbi lomwe limasonkhana pankhope ya sensa).
Kukonza ndi kukhazikitsa zinthu n'kosavuta, koma magwiridwe antchito amatha kuchepa m'malo ovuta.
7. Nthawi Yoyankha:
Chiyeso cha Radar Level:
Ili ndi nthawi yoyankha mwachangu kwambiri, nthawi zambiri imakhala mu milliseconds.
Izi zimapangitsa kuti ikhale yoyenera kuwunika nthawi yeniyeni, makamaka munjira zosinthika.
Chiyeso cha Mulingo wa Ultrasonic:
Nthawi yoyankha nayonso ndi yachangu, koma imatha kukhala yocheperako poyerekeza ndi radar, makamaka pamene zinthu zachilengedwe zikusintha.
8. Mtundu:
Chiyeso cha Radar Level:
Imatha kuyeza kuyambira mamilimita ochepa mpaka kupitirira mamita 70, kutengera mtundu ndi momwe yagwiritsidwira ntchito.
Zoyenera kwambiri poyeza kutalika.
Chiyeso cha Mulingo wa Ultrasonic:
Kawirikawiri amakhala ndi malo oyesera afupiafupi kuposa radar, nthawi zambiri mpaka mamita 3-40.
Mphamvu ya mafunde a mawu ndi mtundu wa zinthu zomwe zikuyesedwa zimachepa.
