Cov keeb kwm kev loj hlob ntawm cheeb tsam-ceev flow meter los ntawm Lanry

Peb cheeb tsam tshaj tawm flow meter yog ib hom kev ntsuas ntws hauv cov channel qhib thiab cov yeeb nkab ib nrab.Cheeb Tsam-Velocity Doppler flowmeter yog qhov zoo los xam qhov txaus, tus nqi ntws thiab qib ntsuas rau txhua yam kua dej (los ntawm me ntsis qias neeg mus rau cov dej qias neeg) los ntawm kev sojntsuam ultrasonic thiab kev sojntsuam siab.Kev sojntsuam yog mounted hauv cov yeeb nkab thiab hauv qab ntawm qhib channel.

Thaj chaw tshaj tawm cov kua flowmeter ua haujlwm zoo ntawm cov kev qhib rau kev kho cov dej khib nyiab, cov dej ntws ntws tawm, cov dej khib nyiab kho cov nroj tsuag thiab kev ua liaj ua teb dej, kev saib xyuas ib puag ncig, muaj zog ntws thiab cua daj cua dub saib, dej hauv av, thiab lwm yam.

Rau kev qhib channel thiab tsis puv cov yeeb nkab doppler flow meter, nws muaj cov hauv qab no zoo:

1. Nws tsis tas yuav muaj flume lossis weir thiab yooj yim rau nruab;

2. 4.5 nti xim LCD zaub thiab Ip68 tiv thaiv chav kawm, nws muaj peev xwm ua kom pom tau tias tus nqi ntws, tshaj tawm, tag nrho, qib thiab lwm yam ntaub ntawv tseem ceeb los ntawm LCD zaub;

3. Kev ntsuas zoo heev ntawm cov kua theem, conductivity, ntws thiab ntws tus nqi;

4. Cov ntaub ntawv logger muaj nuj nqi ultrasonic flow meter rau cov ntaub ntawv saib xyuas thiab tshaj tawm;

5.

Lub evolve ntawm cheeb tsam tshaj tawm ultrasonic flow meter raws li hauv qab no:

Xyoo 1996, peb tau tsim thawj tiam QSD6526 doppler ntws sensor.

Doppler ultrasonic flowmeter tuaj yeem ntsuas qhov nrawm nrawm ntawm cov kua thiab qib dej los ntawm kev ntsuas siab.

Cheeb Tsam tshaj tawm doppler ntws ntsuas nrog cov qauv nplaum

1. Qhov kev khiav ceev yog los ntawm 21mm / s txog 4500mm / s

2. Kev ntsuas qib yog los ntawm 0 txog 2m thiab 0 txog 5m.

3. Qhov tseeb yog 2%

Hauv xyoo 2014, peb tau pib lub ntsuas thib ob: QSD6527 doppler flow sensor.

Qhov hloov tshiab ua haujlwm ntawm cheeb tsam tshaj tawm ultrasound flowmeter raws li hauv qab no:

1. Cov kua theem yog ntsuas los ntawm ultrasonic sensor, tsis yog siab sensor;

2. Nws txais yuav epoxy-sealed lub cev tsim thiab tuaj yeem ua tiav bidirection kua ntws ntsuas;

Nyob rau hauv 2018, peb tau tshaj tawm qhov tseeb version cheeb tsam tshaj tawm doppler txaus saib: QSD6537 doppler ntws sensor.

1. Ntxiv kev ua haujlwm ntawm kev ntsuas kev ntsuas;

2. Kev ntsuas qib hauv cov kua dej tuaj yeem ntsuas los ntawm ob txoj kev: ultrasonic sensor thiab siab sensor;

3. Ntxiv cov haujlwm ntawm barometric siab thiab kub them nyiaj;

4. Qhov ntsuas no adpots digital DSP doppler thev naus laus zis, tsis yog simulation doppler tech.Qhov tseeb yog ± 1%;

5. Qhov khiav ceev ntawm qhov ntsuas no yog los ntawm 20mm / s txog 12 m / s;

6. Qib ntau yog 20mm mus rau 5m los ntawm ultrasonic sensor thiab 0mm mus rau 10mm los ntawm lub siab sensor;

7. Qhov ntsuas tshiab no tuaj yeem ntsuas cov kua dej huv;

8. Kev sojntsuam ntxiv Modbus RTU tso zis;
