Lub sijhawm sib txawv ntawm hom ultrasonic flowmeter yog ntsuas siv Ib khub ntawm transducers (sensors A thiab B hauv daim duab hauv qab), uas hloov pauv (lossis ib txhij) xa thiab tau txais ultrasonic tsis.Lub teeb liab taug kev nrawm dua li ntws hauv cov kua dej, thiab lub sijhawm sib txawv yog xoom thaum cov kua dej tseem nyob.Yog li ntawd, ntev npaum li lub sij hawm ntawm downstream thiab countercurrent propagation yog ntsuas, qhov txawv tus nqi △t yuav tau.Tom qab ntawd, raws li kev sib raug zoo ntawm △ T thiab qhov tshaj tawm V, qhov nruab nrab qhov nrawm ntawm qhov nruab nrab tuaj yeem ntsuas qhov tsis ncaj, thiab qhov ntim ntws Q tuaj yeem suav tau raws li qhov chaw hla ntu.
V = K*△ t
Q = S × V, qhov twg K yog qhov tas mus li thiab S yog qhov chaw hla ntu hauv cov yeeb nkab.
Lub transit-time ultrasonic flowmeter yog tsim rau ntsuas cov kua huv si hauv cov yeeb nkab kaw tag nrho, thiab cov ntsiab lus ntawm cov khoom raug tshem tawm lossis npuas hauv cov kua ntsuas tsawg dua 5.0%.Hom flow meter no tuaj yeem siv dav hauv cov kua dej hauv qab no.
1) Cov kav dej, cov dej ntws, dej txias, dej kub, thiab lwm yam;
2) Cov dej tsis huv, dej hiav txwv, dej phwj tuaj, lossis dej phwj thib ob;
3) Dej haus, cawv, npias, kua tshuaj, thiab lwm yam;
4) tshuaj hnyav, mis nyuj, yogurt, thiab lwm yam .;
5) roj av, kerosene, diesel, thiab lwm yam khoom siv roj;
6) Fais fab nroj tsuag (nuclear, thermal, thiab hydraulic), cua sov, cua sov, cua sov;
7) Flow collection, leak detection;Flow, kub quantization tswj, saib xyuas network system;
8) metallurgy, mining, roj av, tshuaj lom neeg kev lag luam;
9) Kev saib xyuas kev txuag hluav taws xob thiab kev txuag dej;
10) Khoom noj khoom haus thiab tshuaj;
11) Kev ntsuas kub thiab ntsuas kub sib npaug;
12) On-site flow meter calibration, calibration, cov ntaub ntawv ntsuam xyuas, thiab lwm yam.
