Makhalidwe ndi kusiyana kwa ultrasound flowmeter ndi electromagnetic flowmeter motsatana

Choyezera kuyenda kwa ma ultrasound ndi choyezera kuyenda kwa ma electromagnetic ndi zida zodziwika bwino zoyezera kuyenda kwa ma electromagnetic, zomwe zili ndi mawonekedwe osiyanasiyana komanso magawo ogwiritsira ntchito.

Choyezera kuyenda kwa ma ultrasound:

Mawonekedwe:

1. Yosavulaza, yopanda kutayika kwa kuthamanga;

2. Kukhazikitsa kosavuta, mtengo wotsika wokonza;

3. Kuyeza kwakukulu, kumatha kuyeza kutentha kwambiri, madzi ndi mpweya wambiri;

4. Kapangidwe ka njira yoyendera madzi ndi kosinthasintha ndipo koyenera zochitika zosiyanasiyana ndi mainchesi a mapaipi.

Kusiyana kwake:

1. Mfundo yoyezera: Choyezera kuyenda kwa magetsi chimagwiritsa ntchito ukadaulo wa ultrasonic poyesa kuchuluka kwa kayendedwe ka madzi, chimatumiza mafunde a ultrasound kupita ku sing'anga kuti chiyesedwe kudzera mu sensa, kenako chimalandira chizindikiro chobwerera, chimawerengera kuchuluka kwa madzi malinga ndi liwiro la kufalikira kwa mafunde a ultrasound mu sing'anga; Choyezera kuyenda kwa magetsi chimagwiritsa ntchito lamulo la Faraday poyesa kulowetsedwa kwa mphamvu ya maginito ya tinthu tomwe timayendetsedwa ndi magetsi mu conductive media.

2. Mikhalidwe yosiyanasiyana chifukwa cha kusokoneza chilengedwe: chifukwa ma flowmeter a ultrasonic amafunika kutumiza ndikulandira zizindikiro za ultrasound, amakhudzidwa kwambiri ndi zinthu zakunja monga phokoso ndi phokoso, ndipo amakhala pachiwopsezo chachikulu cha kusokoneza chilengedwe kuposa ma flowmeter a electromagnetic.

Choyezera kayendedwe ka maginito amagetsi:

Mawonekedwe:

1. Kulondola kwambiri, kukhazikika bwino kwa muyeso kwa nthawi yayitali;

2. Sizigwira ntchito, sizisuntha ziwalo, komanso zodalirika kwambiri;

3. Kugwiritsa ntchito mosiyanasiyana, kumatha kuyeza madzi oyendetsera mpweya.

Kusiyana:

1. Mfundo yoyezera: Monga tafotokozera pamwambapa, electromagnetic flowmeter ndi kugwiritsa ntchito tinthu tamagetsi tomwe timayendetsedwa ndi magetsi mu conductive medium yomwe imayambitsidwa ndi mphamvu yakunja ya maginito kuti isinthe chizindikiro chamagetsi kuti ipeze deta yeniyeni ya mayendedwe.

2. Mikhalidwe yosiyanasiyana chifukwa cha kusokoneza chilengedwe: Popeza mafunde amagetsi amakhudza kwambiri ma flowmeter amagetsi, kugwiritsa ntchito kwake ndikosavuta kuchepetsedwa m'malo ovuta kapena mikhalidwe yovuta monga ma radiation otumizira ma frequency apakati ndi kuwala kwamphamvu ku Asia.
