Ubwino ndi kuipa kwa mita ya radar poyerekeza ndi mita ya ultrasonic

Radamita yoyezera mulingondipo mita yoyezera mulingo wa ultrasound ndi zida zoyezera mulingo zomwe zimagwiritsidwa ntchito kwambiri, zotsatirazi ndi zabwino ndi zoyipa za mita yoyezera mulingo wa radar poyerekeza ndi mita yoyezera mulingo wa ultrasound:
ubwino
Kulondola kwambiri kwa muyeso: choyezera mulingo wa radar chimagwiritsa ntchito mfundo ya microwave reflection poyezera, yomwe simakhudzidwa ndi kusintha kwa kutentha, kuthamanga, kuchulukana, chinyezi ndi zinthu zina, ndipo kulondola kwa muyeso kumakhala kwakukulu, nthawi zambiri mpaka ±1mm kapena kupitirira apo. Kulondola kwa muyeso wa ultrasound level meter kumakhudzidwa kwambiri ndi zinthu monga mawonekedwe apakati ndi kutentha kwa malo ozungulira, ndipo kulondola nthawi zambiri kumakhala pafupifupi ± 3mm-± 5mm.
Ntchito zosiyanasiyana
Kusinthasintha kwapakati: Chiyeso cha radar level chimatha kuyeza kuchuluka kwa madzi a zinthu zosiyanasiyana zamadzimadzi ndi zolimba, kuphatikizapo kuwononga, kukhuthala, kupangika mosavuta kwa makristalo ndi zinthu zina zapadera. Poyeza sing'anga yokhala ndi kukhuthala kwakukulu, kupangika kosavuta kwa makristalo kapena thovu, choyezera cha ultrasonic level chingakhale ndi kuchepa kwa chizindikiro kapena kuwunikira kosakhazikika.
Malo otentha kwambiri komanso opanikizika kwambiri: choyezera radar level chingagwire ntchito bwino pamalo otentha kwambiri (mpaka 400℃ kapena kuposerapo) komanso opanikizika kwambiri (mpaka 40MPa kapena kuposerapo). Chifukwa cha kuchepa kwa zinthu zosinthira ndi mfundo zake, kuchuluka kwa mita yamadzimadzi ya ultrasonic yomwe imagwiritsidwa ntchito pamalo otentha kwambiri komanso opanikizika kwambiri ndi kochepa.
Kuchuluka kwa malo: Kuchuluka kwa malo oyezera a radar level meter ndi kwakukulu, komwe nthawi zambiri kumatha kufika mamita makumi kapena mazana a mamita, ndipo ndikoyenera kuyeza madzi m'matanki akuluakulu osungiramo zinthu ndi nsanja zazitali. Kuchuluka kwa malo oyezera a ultrasonic level meter nthawi zambiri kumakhala mkati mwa mamita khumi.
Mphamvu yolimbana ndi kusokoneza: chizindikiro cha microwave chomwe chimachokera ku radar level meter sichisokonezedwa ndi mafunde akunja a electromagnetic, mafunde amawu ndi zizindikiro zina, ndipo chizindikirocho chimakhala chokhazikika komanso chodalirika. Mu malo okhala ndi phokoso lamphamvu, kugwedezeka kapena nthunzi, ultrasound level meter imakhala ndi kusokoneza, zomwe zimapangitsa kuti zolakwika zoyezera ziwonjezeke.
Zofunikira pakuyika ndi zochepa: mita ya radar level siikhudzidwa ndi zopinga ndi zoyambitsa zomwe zili mu chidebecho ikayikidwa, bola ngati antenna sinatsekedwe. Mita ya Ultrasonic level siifuna zopinga zomwe zili pamwamba pa mulingo wamadzimadzi, apo ayi idzakhudza kufalikira ndi kuwonekera kwa mafunde amawu, zomwe zimapangitsa kuti muyeso ukhale wolakwika.
Udindo wotsika
Mtengo wokwera: Kuchuluka kwa ukadaulo wa mita ya radar ndi kokwera, ndipo njira yopangira ndi yovuta, kotero mtengo wake ndi wokwera mtengo kwambiri kuposa mita ya ultrasonic level, yomwe imachepetsa kuchuluka kwa momwe imagwiritsidwira ntchito pamlingo winawake, makamaka nthawi zina zomwe zimakhala zovuta.
N'kovuta kuyeza sing'anga ndi dielectric constant yaing'ono: pa sing'anga ndi dielectric constant yaing'ono, chizindikiro chowonetsedwa cha radar wave ndi chofooka, zomwe zingakhudze kulondola kwa muyeso. Choyezera madzi cha ultrasonic sichimazindikira dielectric constant ya sing'anga, ndipo ndi choyenera kwambiri kuyeza sing'anga ndi kusintha kwakukulu kapena kochepa kwa dielectric constant.
Pali malo osawona: choyezera mulingo wa radar chili ndi malo enaake osawona pafupi ndi poyambira poyezera, nthawi zambiri masentimita makumi ambiri mpaka pafupifupi mita imodzi, ndipo sichingathe kuyeza mulingo wamadzimadzi pafupi kwambiri ndi pansi. Malo osawona a choyezera mulingo wa ultrasound ndi ochepa, nthawi zambiri pakati pa masentimita ochepa ndi masentimita makumi ambiri.
Kusalowa bwino kwa chizindikiro: mafunde a radar sangalowe m'zinthu zolimba zowunikira monga chitsulo, ngati chidebecho ndi chachitsulo ndipo mkati mwake muli mkati kapena chotchingira, chingakhudze kufalikira ndi kuwunikira kwa mafunde a radar, muyenera kugwiritsa ntchito njira yapadera yoyikira kapena kusankha chitsanzo choyenera cha radar level gauge. Mafunde a phokoso la ultrasound level meter amatha kulowa m'makulidwe enaake a zinthu zosakhala zachitsulo, ndipo kusinthasintha kwa zinthu ndi kapangidwe ka chidebecho ndikwabwino.
