Ultrasonic Flow Meters

20+ Xyoo Kev Tsim Khoom

Ultrasonic flow meter thiab magnetic flow meter

Ultrasonic flowmeter

Qhov zoo ntawm acoustic flowmeter:

1. Kev ntsuas tsis sib cuag

2. Tsis muaj kev ntsuas kev khiav dej num, tsis muaj kev poob siab.

3. Cov kua uas tsis yog-conductive tuaj yeem ntsuas tau.

4. Txoj kab uas hla dav dav

5. Dej, roj, roj, txhua yam kev tshaj tawm tuaj yeem ntsuas tau, nws daim ntawv thov teb yog dav heev.

Disadvantages ntawm ultrasonic flowmeter:

1. Muaj qee qhov kev txwv hauv kev ntsuas cov xov xwm kub kub.

2. Cov kev xav tau siab rau qhov kub ntawm qhov chaw ntws.

3. Qhov ntev ntawm cov yeeb nkab ncaj yog yuav tsum tau.

Electromagnetic flowmeter muaj ntau yam zoo hauv cov dej ntws thiab yog siv dav hauv ntau yam lag luam.

1 Tsis muaj qhov cuam tshuam qhov ntws ntawm cov yeeb nkab ntsuas, tsis muaj qhov poob siab, thiab qhov yuav tsum tau muaj ntawm cov yeeb nkab ncaj nraim yog qhov tsawg;

2 Kev ntsuas qhov tseeb, muaj zog ruaj khov, muaj peev xwm tiv thaiv kev vibration cuam tshuam;

3 Kev ntsuas tsis cuam tshuam los ntawm kev hloov pauv ntawm cov kua dej ntom ntom, viscosity, kub, siab thiab conductivity;

4 Nrog ntau yam electrodes thiab hauv ob sab phlu kev xaiv, muaj zog tiv thaiv dielectric corrosion.

Tau kawg, electromagnetic flowmeters muaj lawv tus kheej cov kev txwv:

1 Lub ntsuas nruab nrab yuav tsum muaj qee yam conductivity (feem ntau ntau dua 5us / cm), thiab kuj tseem muaj qee qhov yuav tsum tau ntsuas qhov pib khiav nrawm (feem ntau ntau dua 0.5m / s).

2 Qhov ntsuas kub ntawm qhov ntsuas nruab nrab yog txwv los ntawm cov khoom siv hauv ob sab phlu, thiab kev ntsuas qhov ntsuas kub nruab nrab tsis zoo.

3 Tsis tuaj yeem ntsuas roj, vapor thiab lwm yam xov xwm.

4 Yog tias ntsuas electrode ua haujlwm ntev, tej zaum yuav muaj qhov ntsuas, uas tuaj yeem ntsuas tsuas yog tom qab ntxuav.

5 Rau lub siab viscosity nruab nrab thiab cov khoom-kua ob-theem nruab nrab, nws yog ib qho tsim nyog yuav tsum tau siv lub zog siab excitation, tsawg zaus tsawg magnetic raug.

6 Vim qhov kev txwv ntawm lub ntsiab lus sensor qauv, tus nqi ntawm cov khoom loj-caliber yog siab dhau lawm, ua rau cov khoom caliber nce thiab nqi.

7 Vim nws txoj cai txwv, lub ntsuas ntsuas ntsuas lub kauj yuav tsum tau ua kom muaj zog los ua kom muaj qhov sib nqus, thiab qhov kwv yees siv hluav taws xob yog qhov siab, uas tsis haum rau lub roj teeb lub zog.

Kev sib piv

1. Sib nqus flowmeter raug siab dua li ultrasonic flowmeter's.

2. Electromagnetic flowmeter tus nqi cuam tshuam los ntawm cov yeeb nkab diameters, tab sis rau clamp ntawm ultrasonic flow meter, nws tus nqi tsis cuam tshuam nrog cov yeeb nkab txoj kab uas hla.

3. Magentic flow meter tsis muaj clamp ntawm hom, ultrsonic flow meter yog xaiv tau rau clamp rau, tuaj yeem ua tiav cov dej ntws tsis sib cuag.

4. Ultrasonic flow meter tuaj yeem ua haujlwm nrog cov kua dej tsis zoo, zoo li dej ntshiab.Electromagnetic flow meter tsuas yog tuaj yeem ntsuas cov kua ua kua.

5. Eletromagnetic flow meter tsis tuaj yeem ntsuas cov kua kub kub, tab sis ultrasonic flow meter yog ok rau cov kua kub kub.
