Mbiri yachitukuko cha dera-velocity flow mita kuchokera ku Lanry

Malo athu othamanga mita ndi mtundu wa zida zoyenda munjira yotseguka komanso chitoliro chodzaza pang'ono.Area-Velocity Doppler flowmeter ndi bwino kuwerengera kuthamanga, kuchuluka kwa mayendedwe ndi mulingo wamitundu yonse yamadzimadzi (kuchokera pazamadzi zonyansa pang'ono mpaka zamadzimadzi zonyansa kwambiri) ndi kafukufuku wa akupanga ndi kafukufuku wokakamiza.Chofufuzacho chimayikidwa mkati mwa chitoliro ndi pansi pa njira yotseguka.

Area velocity fluid flowmeter imagwira ntchito bwino pamakina otseguka oyeretsera madzi oyipa, chowunikira madzi otaya madzi, malo opangira madzi otayira m'mafakitale ndi ulimi wothirira, kuyang'anira chilengedwe, kuyenda kwamphamvu ndi kuwunika kwamadzi amkuntho, madzi apansi, ndi zina zambiri.

Kwa njira yotseguka osati mita yodzaza chitoliro cha doppler, ili ndi zabwino pansipa:

1. Sichifuna flume kapena weir ndi zosavuta kukhazikitsa;

2. 4.5 inchi mtundu LCD anasonyeza ndi Ip68 kalasi chitetezo, akhoza mwangwiro kusonyeza kuti otaya mlingo, liwiro, totalizer, mlingo ndi mfundo zina zofunika ndi LCD anasonyeza;

3. Mtengo wabwino kwambiri wa kuyeza kwamadzimadzi, kuwongolera, kuyenda ndi kuthamanga;

4. Data logger ntchito akupanga otaya mita kwa deta polojekiti ndi lipoti;

5.

Kusinthika kwa dera liwiro akupanga otaya mita monga pansipa:

Mu 1996, ife anapezerapo m'badwo woyamba QSD6526 doppler flow sensa.

Doppler akupanga flowmeter akhoza kuyeza otaya liwiro la madzi ndi madzi mlingo ndi kuthamanga kachipangizo.

Chida chothamanga cha m'dera la liwiro la doppler chokhala ndi zida zomatira

1. Kuthamanga kwa liwiro kumachokera ku 21mm / s kufika ku 4500mm / s

2. Mulingo wa muyeso umachokera ku 0 mpaka 2m ndi 0 mpaka 5m.

3. Kulondola ndi 2%

Mu 2014, tinayambitsa mita ya m'badwo wachiwiri: QSD6527 doppler flow sensor.

Ntchito yosinthidwa ya dera velocity ultrasound flowmeter motere:

1. The madzi mlingo anayeza ndi akupanga sensa, osati kuthamanga sensa;

2. Imatengera kapangidwe ka thupi losindikizidwa ndi epoxy ndipo imatha kutsata kuyeza koyenda kwamadzimadzi;

Mu 2018, tidayambitsa mtundu waposachedwa kwambiri wa dera la velocity doppler flow monitor: QSD6537 doppler flow sensor.

1. Onjezani ntchito ya kuyeza kwa conductivity;

2. Kuyeza kwa mlingo mumadzimadzi kungayesedwe ndi njira ziwiri: akupanga sensa ndi kuthamanga sensa;

3. Onjezani ntchito ya kupanikizika kwa barometric ndi malipiro a kutentha;

4. Mamita awa amatsatsa ukadaulo wa digito wa DSP doppler, m'malo mwaukadaulo woyeserera wa doppler.Kulondola ndi ± 1%;

5. Kuthamanga kwa liwiro la mita iyi kumachokera ku 20mm / s mpaka 12 m / s;

6. The mlingo osiyanasiyana 20mm kuti 5m ndi akupanga sensa ndi 0mm kuti 10mm ndi kuthamanga sensa;

7. Mamita osinthidwawa amatha kuyeza zakumwa zoyera;

8. Kufufuza kumawonjezera kutulutsa kwa Modbus RTU;
