Ndi Madzi Ati Oyenera Kugwiritsa Ntchito Ma Clamp-On Doppler Flowmeters?

Ma flowmeter a Clamp-on DopplerNdi oyenera kwambiri zakumwa zokhala ndi kuchuluka kwa ma acoustic scatterer, kutengera mfundo ya Doppler effect kuti ayesere liwiro la kuyenda mwa kuzindikira kusintha kwa mafunde a phokoso omwe amawonetsedwa ndi ma scatterer (monga tinthu tating'onoting'ono, thovu) m'madzi. Pansipa pali mitundu yeniyeni yamadzimadzi ndi zinthu zofunika kwambiri pakugwiritsa ntchito kwawo:

Mitundu Yamadzimadzi Yoyenera Kwambiri
1. Zakumwa zokhala ndi tinthu tolimba
Zofalitsa Zachizolowezi:
Zimbudzi, matope, mchere wa m'madzi, mapepala, madzi otayira a m'mafakitale (okhala ndi tinthu monga matope, zinyalala, ulusi, nthawi zambiri tinthu tating'onoting'ono tosakwana ≥30 μm).
Zakumwa zodzaza ndi tinthu tating'onoting'ono mumakampani azakudya (monga madzi a zipatso ndi zamkati, sosi, zakumwa zokhala ndi tirigu).
Zoyimitsidwa mumakampani opanga mankhwala (monga, zosakaniza za tinthu tating'onoting'ono ta catalyst, slurry ya pigment).
Zofunikira Zofunikira:
Kuchuluka kwa tinthu tating'onoting'ono kuyenera kukhala ≥100 ppm kuti zitsimikizire kuti pali zizindikiro zokwanira zowunikira mawu.
Kuyimitsidwa kwa mawu kwa tinthu tating'onoting'ono kuyenera kusiyana kwambiri ndi kwa madzi (monga, tinthu tating'onoting'ono tolimba timawonetsa bwino kuwala chifukwa cha kusiyana kwakukulu kwa kuyimitsidwa ndi madzi).
2. Zakumwa zokhala ndi thovu
Zofalitsa Zachizolowezi:
Kuyenda kwa gasi ndi madzi m'magawo awiri (monga madzi a mafakitale okhala ndi thovu la mpweya, madzi owiritsa mowa).
Madzi okhuthala kapena opumira mpweya (monga madzi otuluka m'matanki opumira mpweya pokonza madzi a zinyalala).
Zoganizira:
Ma thovu ayenera kufalikira mofanana mu madzi, kupewa "magulu a mpweya" kapena mpweya wochuluka (zomwe zingayambitse kufalikira kwa chizindikiro chosakhazikika).
3. Zakumwa Zozungulira kapena Zosawoneka Bwino
Zochitika Zachizolowezi:
Madzi omwe njira zoyezera kuwala (monga maginito flowmeters) sizigwira ntchito bwino chifukwa cha kusalowa bwino kwa madzi (monga mankhwala akuda, madzi amatope).
Ma phala kapena ma emulsions mumakampani azakudya (monga msuzi wa chokoleti, mafuta osungunuka).
