Ultrasonic Flowmeter
Amfanin acoustic flowmeter:
1. Ma'aunin kwarara mara lamba
2. Babu ma'aunin toshewar kwarara, babu asarar matsa lamba.
3. Ana iya auna ruwa mara amfani.
4. Wide bututu diamita kewayon
5. Ana iya auna ruwa, gas, mai, kowane nau'in watsa labarai, filin aikace-aikacensa yana da fadi sosai.
Rashin hasara na ultrasonic flowmeter:
1. Akwai wasu iyakoki a auna ma'aunin zafi da zafi.
2. Babban buƙatun don zafin jiki na filin kwarara.
3. Ana buƙatar tsawon sashin bututu madaidaiciya.
Electromagnetic flowmeter yana da fa'idodi da yawa a cikin kwararar ruwa kuma ana amfani dashi ko'ina a masana'antu daban-daban.
1Babu sassa masu hana ruwa gudu a cikin bututu mai aunawa, babu asarar matsa lamba, kuma buƙatun ɓangaren bututun madaidaiciya ba su da ƙarancin ƙarfi;
2 Babban ma'auni, kwanciyar hankali mai ƙarfi, ƙarfin tsoma baki mai ƙarfi;
3 Ba a shafar ma'auni ta canje-canje a cikin yawan ruwa, danko, zafin jiki, matsa lamba da haɓakawa;
4 Tare da nau'ikan na'urorin lantarki da zaɓuɓɓukan sutura, juriya mai ƙarfi ga lalatawar dielectric.
Tabbas, na'urorin lantarki na lantarki suna da nasu iyakoki:
1 Matsakaicin ma'auni dole ne ya kasance yana da ƙayyadaddun ɗabi'a (gaba ɗaya mafi girma fiye da 5us/cm), sannan akwai wasu buƙatu don auna saurin gudu na farko (gaba ɗaya mafi girma 0.5m/s).
2 Matsakaicin ma'aunin ma'auni yana iyakance ta kayan rufi, kuma tasirin ma'aunin matsakaicin zafin jiki ba shi da kyau.
3 Ba za a iya auna gas, tururi da sauran kafofin watsa labarai ba.
4 Idan na'urar aunawa tana aiki na dogon lokaci, ana iya samun sikelin, wanda za'a iya auna shi kawai bayan tsaftacewa.
5 Don matsakaicin danko mai ƙarfi da matsakaici mai ƙarfi-ruwa biyu-lokaci, ya zama dole a yi amfani da tashin hankali mai girma, ƙarancin mitar ƙarancin maganadisu.
6 Saboda ƙayyadaddun ƙa'idodin tsarin firikwensin, farashin samfuran manyan ƙira ya yi yawa, yana haifar da haɓaka ƙimar samfur da farashi.
7 Saboda ƙayyadaddun ƙa'idodinsa, na'urar firikwensin kayan aiki yana buƙatar samun kuzari don samar da filin maganadisu, kuma ƙimar wutar lantarki da aka kiyasta yana da girma, wanda bai dace da samar da wutar lantarki ba.
Kwatanta
1. Magnetic flowmeter daidaito ya fi ultrasonic flowmeter ta.
2. Farashin Electromagnetic flowmeter yana shafar diamita na bututu, amma don matsawa akan mita kwararar ultrasonic, farashinsa ba shi da alaƙa da diamita na bututu.
3. Magentic kwarara mita ba ya matsa a kan nau'in, ultrsonic kwarara mita ne na zaɓi don matsa a kan, iya cimma wadanda ba lamba ruwa kwarara mita.
4. Ultrasonic kwarara mita iya aiki tare da non conductive taya, kamar ruwa mai tsabta.Electromagnetic flow Mita kawai na iya auna ruwa masu gudana.
5. Eletromagnetic kwarara mita ba zai iya auna sosai high zafin jiki taya, amma ultrasonic kwarara mita ne ok zuwa high zafin jiki taya.
