Yiziphi izinkinga ezingase zihlangabezane nazo lapho usebenzisa ama-fluid ultrasonic flowmeters?

I-fluid ultrasonic flowmeter iwuhlobo lomehluko wesikhathi sokugeleza kwe-ultrasonic, efanelekile ukulinganisa ukugeleza kweziphuzo ezihlukahlukene ezihlanzekile nezifanayo.I-interface yayo enhle yomshini womuntu yenza umsebenzisi abe lula futhi akhumbule kalula lapho ebeka imingcele, futhi igcina ikhwalithi enhle kakhulu nokwethembeka okuphezulu.

Ngokomgomo wokutholwa kwesignali i-flowmeter ye-ultrasonic ingahlukaniswa ngendlela yokuhlukanisa isivinini sokusakazeka (indlela yokuhlukanisa isikhathi esiqondile, indlela yokuhlukanisa isikhathi, indlela yomehluko wesigaba kanye nendlela yokuhlukanisa imvamisa), indlela yokufuduka kwe-beam, indlela ye-Doppler, indlela yokuxhumana, isihlungi sesikhala. indlela kanye nendlela yomsindo.

I-fluid ultrasonic flowmeter kanye ne-electromagnetic flowmeter, ngoba isiteshi sokugeleza kwensimbi asimiswanga noma yikuphi ukuvinjelwa, yi-flowmeter yokuqala, ifaneleka ukuxazulula inkinga enzima yokulinganisa ukugeleza kwekilasi le-flowmeter, ikakhulukazi esilinganisweni esikhulu sokugeleza sinokubonakala okuvelele. inzuzo, ingenye yentuthuko esheshayo yekilasi le-flowmeter.

I-fluid ultrasonic flowmeters ingase ihlangabezane nezinkinga ezilandelayo:

1. Lapho indlela yokudlulisa iqukethe ukungcola okuwuketshezi njengamanzi, ithubhu yokucindezela i-flowmeter kulula ukukhiqiza ukuqoqwa kwe-liquid, futhi ukuqandisa kweshubhu lokucindezela kuzokwenzeka lapho izinga lokushisa liphansi, ikakhulukazi ebusika esifundeni esisenyakatho.Isixazululo: Hlanza ishubhu lokucindezela noma wengeze umkhondo wokushisa kagesi.

2, izidingo zepayipi ziqinile kakhulu azikwazi ukuba nomsindo ongajwayelekile, ngaphandle kwalokho kuzothinta iphutha lokulinganisa likhulu kakhulu.Ngenqubo yokusabalalisa, ngenxa yokuvinjelwa noma ukumuncwa kwe-medium kanye nokungcola okuphakathi, amandla ayo azoncishiswa.Kungakhathaliseki ukuthi i-flowmeter ye-ultrasonic noma imitha yezinga le-ultrasonic, kunezidingo ezithile ze-acoustic wave intensity eyamukelekayo, ngakho-ke zonke izinhlobo zokunciphisa kufanele zicindezelwe.

3, ukushintshashintsha kokugeleza okusheshayo kukhulu?

Amandla esignali makhulu, futhi uketshezi olulinganiselwe lushintshashintsha kakhulu.Isixazululo: Lungisa indawo ye-probe, uthuthukise amandla esignali, ukuze uqinisekise ukuthi amandla esignali azinzile, njengokuguquguquka koketshezi lwawo, indawo ayilungile, khetha kabusha iphuzu.
