Ubwino ndi Kuipa kwa Doppler Flowmeters

Ngakhale kuti Doppler ultrasonic flowmeter si yolondola kwambiri monga transit time ultrasonic flow meter, Doppler flowmeter imatha kuyeza zakumwa zodetsedwa (koma singathe kuyeza zakumwa zoyera), Doppler flow meter imatha kuyeza kuyenda kwa zimbudzi chifukwa zimbudzi zimakhala ndi zinthu zambiri zolimba, nthawi yomweyo, imayesedwanso zamadzimadzi okhala ndi thovu la mpweya wambiri;

Pali malire ena okhudza doppler flowmeter:

1. Kuzindikira kusintha kwa kutentha

Ma transducer a Doppler flow ndi okhudzidwa kwambiri ndi kusintha kwa kutentha, kuchuluka, ndi kuchulukana kwa zinthu, pamene zinthu zomwe zili mu chitolirocho zikusintha pang'ono, zimatha kukhala ndi zotsatira zoyipa pakuyesa kuyenda kwa zinthu;

2. Zoletsa za mtundu wa madzimadzi

Choyezera kuyenda kwa doppler sichiyesa madzi oyera, madzi okhuthala kwambiri, matope a pepala, zamkati, ndi zina zotero.

3. Zoletsa zosankha zotuluka

Doppler flow meter ikupezeka mu 4-20mA, Pulse, Relay output, no data logger, RS485 modbus, GPRS, ndi zina zotero. (Kupatula area-velocity floemeter)
