DW901 jerin matsin lamba matsin lamba matakin mai watsawa ne wani ma'auni na ma'auni tare da matsin lamba matsin lamba ka'idar, wanda ya ƙunshi high daidaito, high kwanciyar hankali IC yaduwa silicon matsin lamba juriya firikwensin da guda kawai daidaito hadedden mai watsawa kewayawa. Za a iya canza matakin ruwa zuwa 4 ~ 20mA DC misali halin yanzu siginar, da gida ne 316L bakin karfe hatimi tsari. Don haka aka auna da sarrafa matakin ruwa.
An tsara kayayyakin don ma'auni na tanks, tsabtace ruwa a masana'antu kamar man fetur, sinadarai, wutar lantarki, takarda, abinci, magunguna da sauransu, da kuma ma'auni na ruwa a injiniyan ruwa, tashoshin ruwa, ruwan karkashin kasa, ruwan ruwa, tashoshin ruwa, tafkuna, tashoshin wutar lantarki da sauran lokuta.

Tare da 316L bakin karfe gida, IC SENSORS high-yi matsin lamba firikwensin auna tsayayye ruwa matakin. Yana da kyau ta hanyar zafin jiki, linear da maimaitawa. Jigilar sassan duk da bakin karfe tsari, lalata juriya ƙarfi ba motsawa sassa, sealability mai kyau, sauki shigarwa za a iya amfani da lalata ƙarfi ko m ruwa.

DW901 jerin matsin lamba matakin mai watsawa ya ƙunshi sassa uku na ma'aunin bincike, akwatin haɗi, da kuma haɗin haɗi. Matsin lamba mai auna matsin lamba yana amfani da binciken matsin lamba don auna matakin ruwa a kasa na kwantena, matsin lamba na ruwa yana nunawa ta hanyar formula P = Po + ρgh. inda Po shine matsin lamba na sama na ruwa, ρ shine yawan ruwa da aka auna, H shine tsawon madaidaicin ruwa, da g shine hanzarin nauyi (daidaitacce). Don kawar da tasirin matsin lamba na sama na ruwa, mai watsawa na DW901 yana amfani da tsarin ƙirar kebul mai iska don shigo da PO zuwa bayan matsin lamba na firikwensin don daidaita tasirin Po. A gani, matsin lamba P da aka gano na'urar firikwensin yana da alaƙa ta layi da matakin ruwa da aka gwada. Matsin lamba siginar da daya yanki hadedde V / I mai watsawa canza zuwa 4 ~ 20mA DC fitarwa siginar, auna (rikodin) fitarwa yanzu darajar girman, za a iya auna tsawo na ruwa matakin. Lokacin da fitarwa halin yanzu ya kai da aka saita halin yanzu darajar, ta hanyar wani zaɓi sayen kayan aiki mai kula, za a iya fitar da iko ko ƙararrawa siginar.
Dole ne a dakatar da binciken firikwensin ko a sanya shi a kan wani wuri mai tsayi don cimma ainihin manufofin aunawa. Lokacin da kafofin watsa labarai ke gudana ko rikice-rikice masu girma, ya kamata a shigar da binciken a kan tallafin tallafi ko ƙara ƙarfin tuƙuru da sarkar dakatarwa, kuma ana iya sanya binciken a cikin bututun ruwa.
