Ingabe i-ultrasonic flowmeter ingalinganisa ngokunembile lapho ijubane lokugeleza eliphakathi epayipini liphansi kakhulu (isb., < 0.1 m/s) noma liphezulu kakhulu (isb., > 10 m/s)?

Kulesi sigaba, ukugeleza okuphakathi kuseduze nokugeleza kwe-laminar, kanye nokusatshalaliswa kwejubane okungalingani kahle. Ama-flowmeter endlela eyodwa, alinganisa ijubane lokugeleza kuphela esikhungweni sepayipi, azobona iphutha lawo lokuguqulwa likhula lisuka ku-±1% liye ngaphezu kuka-±3%. Ngokuphambene nalokho, ama-flowmeter ezindlela eziningi angagcina ukunemba okungu-±0.5% kuya ku-±1% ngokulinganisa ijubane ezindaweni eziningi nokubala isilinganiso esilinganisiwe. Kodwa-ke, kuyadingeka ukukhetha "uhlobo olukhethekile lwejubane eliphansi lokugeleza" (olunokukhuliswa kwesignali okuphezulu).

Ukugeleza kwesivinini esikhulu kuvame ukukhiqiza umsindo oguquguqukayo, futhi umehluko wesikhathi wokusabalala kwamagagasi e-ultrasonic uba mncane (okwenza kube nzima ukubamba ngokunembile), okungase kuholele ekushintsheni kokugeleza okusheshayo. Kuyadingeka ukukhetha i-flowmeter “yohlobo lwesampula olunemvamisa ephezulu” (enomvamisa wokuthatha isampula ≥ 100 Hz) futhi uqinisekise ukuhlangana okuqinile phakathi kwenzwa kanye nephayiphi (ukunciphisa ukuphazamiseka kokudlidliza).
