Kev ntsuas qhov ceev yog ncaj qha cuam tshuam nrog qhov ceev ntawm lub suab hauv dej. Qhov tseem ceeb uas siv losqhov ntsuas qhov ceev yog raws li qhov ceev ntawm lub suab hauv dej tshiab ntawm 20 ° C (saiblub rooj hauv qab no). Qhov ceev ntawm lub suab no muab qhov ntsuas calibration ntawm 0.550mm / sec ib Hz ntawmDoppler hloov pauv.
Qhov calibration factor no yuav raug kho rau lwm yam mob, piv txwv li qhov calibration factorrau dej hiav txwv yog 0.5618mm/sec/Hz.
Qhov ceev ntawm lub suab sib txawv ntau nrog rau qhov ceev ntawm dej. Qhov ceev ntawm dej yog nyob ntawmsiab, dej kub, salinity thiab sediment cov ntsiab lus. Ntawm cov no, kub muajqhov cuam tshuam tseem ceeb tshaj plaws thiab nws raug ntsuas los ntawm Ultraflow QSD 6537 thiab siv rau hauvkev kho qhov ntsuas ceev.
Lub Ultraflow QSD 6537 kho qhov kev hloov pauv ntawm qhov ceev ntawm lub suab hauv dej vim yogkub siv qhov sib piv ntawm 0.00138mm/s/Hz/°C. Qhov kev kho no yog qhov zoo tshaj plaws rau dejkub ntawm 0 ° C txog 30 ° C.
Cov lus hauv qab no qhia txog qhov ceev ntawm lub suab sib txawv li cas nrog qhov kub thiab txias thiab ntawm cov tshiabthiab dej hiav txwv.
Cov npuas dej hauv dej yog qhov xav tau ua cov khoom tawg, tab sis ntau dhau tuaj yeem cuam tshuam rau qhov ceev ntawm lub suab.
Hauv huab cua qhov ceev ntawm lub suab yog li 350 m / s.
