Kodi ubwino wa choyezera mpweya cha Doppler chotseguka poyerekeza ndi choyezera mpweya cha radar ndi wotani?

Doppler flowmeter yotseguka nthawi zambiri imatanthauza Doppler ultrasonic open channel flowmeter, poyerekeza ndi Doppler radar flowmeter, ili ndi ubwino wotsatira:

Kulondola kwambiri kwa muyeso:Choyezera madzi chotseguka cha Doppler chopangidwa ndi Ultrasonic Doppler chimatha kuyeza kuchuluka kwa madzi m'gawo la madzi, komwe kumatha kuwonetsa bwino momwe madzi amafalikira m'gawo lonse la madzi, ndipo kulondola kwa muyeso nthawi zambiri kumakhala mpaka ± 1% kapena kupitirira apo. Choyezera madzi chopangidwa ndi radar ya Doppler chimayesa kuchuluka kwa madzi pamwamba pa thupi la madzi, ngakhale kuti kuchuluka kwa madzi pamwamba kumatha kusinthidwa kukhala kuchuluka kwa madzi apakati pa gawolo kudzera mu chitsanzo chomangidwa mkati, koma m'mikhalidwe yovuta ya madzi kapena kugwiritsa ntchito koyamba kwa choyezera madzi chokhazikika, kulondola kochepa.

Mphamvu yamphamvu yosinthira ku mikhalidwe yovuta ya kuyenda: Ma Ultrasonic Doppler open channel flowmeters ndi oyenera mikhalidwe yosiyanasiyana ya kuyenda, kuphatikizapo madzi amatope, thovu, ndi kuyenda kwa madzi kosakhazikika. Chifukwa chakuti zimachokera ku kuwunikira kwa tinthu tomwe timayimitsidwa m'madzi kupita ku mafunde a ultrasound kuti tiyese kuchuluka kwa kuyenda, ngakhale pali zinyalala m'madzi, thovu, ndi zina zotero, zimatha kugwira ntchito bwino. Doppler radar flowmeter imakhudzidwa kwambiri ndi kusinthasintha kwa pamwamba pa madzi. Ngati kusinthasintha kwa pamwamba pa madzi kuli kwakukulu, chizindikiro chowunikira cha mafunde a radar sichidzakhala chosakhazikika, motero chimakhudza kulondola kwa muyeso.

Kuchepa kwa mphamvu pa nyengo: Doppler flowmeter yotseguka yomwe yayikidwa pansi pa madzi kapena munjira, yomwe sikhudzidwa ndi kusintha kwa nyengo, monga mvula yamphamvu, mphepo, chifunga, ndi zina zotero, kulondola kwake koyezera ndi kochepa. Doppler radar flowmeter imayesedwa potumiza mafunde a radar pamwamba pa madzi. Nyengo imatha kusokoneza kufalikira ndi kuwonekera kwa mafunde a radar, mwachitsanzo, mvula yamphamvu ingasokoneze chizindikiro cha radar, ndipo mphepo yamphamvu idzawonjezera kusinthasintha kwa pamwamba pa madzi, motero kukhudza kulondola kwa muyeso.

Yoyenera kuyang'anira kosalekeza kwa nthawi yayitali: Popeza choyezera kuyenda kwa Doppler chotseguka sichikhudzidwa kwambiri ndi zinthu zachilengedwe ndipo chimagwira ntchito bwino, ndi choyenera kwambiri kuyang'anira kuyenda kwa nthawi yayitali komanso kosalekeza kwa njira yotseguka, zomwe zingapereke deta yokhazikika komanso yodalirika. Choyezera kuyenda kwa Doppler radar chingasinthe kapena kukhala cholondola pa nyengo yoipa kapena mikhalidwe yapadera yachilengedwe, ndipo kukhazikika kwa kuyang'anira kosalekeza kwa nthawi yayitali ndi koipa pang'ono.
