Ma flow metre osiyanasiyana amagwira ntchito popititsa patsogolo magwiridwe antchito, kulondola komanso kudalirika kwanthawi yayitali. Ndikofunikira kuyang'ana ma nuances amtundu uliwonse ndi momwe akukwaniritsira zofunikira zamakampani. Pezani mtundu wa mita yoyendera kuti mukwaniritse zosowa zenizeni.
Mitundu ya Flow Meters
Misa flow mita
Amisa flow mita, amene amadziwika kuti inertial flow mita, amagwiritsidwa ntchito poyeza kuchuluka kwa madzi omwe akuyenda mu chubu. Kuchuluka kwa madzimadzi omwe akuyenda kudutsa malo okhazikika pa nthawi ya unit amatchedwa mass flow rate. Meta yothamanga kwambiri imayesa kuchuluka kwake m'malo mwa kuchuluka kwa nthawi ya unit (monga ma kgs pa sekondi iliyonse) kutumiza kudzera pa chipangizocho.
Coriolis flow mitaamatengedwa ngati ma flow meters olondola kwambiri obwerezabwereza pakali pano. Amatumiza madzimadzi m'machubu onjenjemera ndikuwona kusintha kwamadziwo. Madzi otuluka kudzera m'machubu onjenjemera amayambitsa kupindika pang'ono kapena kupunduka. Zopindika ndi zopindika zotere zimayenderana mwachindunji ndi kuchuluka kwa mafunde. Mamita a Coriolis amachita zonse ziwirimisa ndi kachulukidwe kuyeza, kukhala wosinthasintha pazinthu zosiyanasiyana monga mafakitale a mankhwala, mafuta, ndi gasi. Zochita zawo zotsogola mwatsatanetsatane komanso kugwiritsidwa ntchito kofala ndizo zifukwa zazikulu za kutchuka kwawo m'mafakitale ovuta.
Mtundu Wotsekereza
Differential Pressure (DP) flow mitazakonzedwa kuti zisinthike pazosowa zamakono zamakampani, kukhalabe njira yodalirika kwambiri pakuwunika ndi kuyeza. Kusiyana kwapakati kumayesedwa pamaziko a mfundo yakuti mgwirizano wina pakati pa kusiyana kwa kuthamanga komwe kumapangidwa pamene madzi amadzimadzi akuyenda kudzera muzitsulo zogwedeza ndi maulendo othamanga. Chipangizo chopukutira ndi chinthu chokokerana chapafupi chomwe chimayikidwa paipi. Zomwe zimagwiritsidwa ntchito kwambiri ndizomapepala obiriwira, mphunondimachubu a venturi,amagwiritsidwa ntchito kwambiri poyezera ndi kuwongolera mafakitale.
A variable area mitaimagwira ntchito poyezera kuchuluka kwa madzimadzi omwe amadutsa gawo la chipangizocho kuti asinthe potengera kuyenda. Zina zoyezeka zimawonetsa kuchuluka kwake. Ma rotameter, chitsanzo cha mita yosinthika, amapezeka pazamadzimadzi ambiri ndipo amagwiritsidwa ntchito ndi madzi kapena mpweya. Chitsanzo china ndi malo ozungulira orifice, momwe kutuluka kwamadzimadzi kumadutsa pamtunda kumasokoneza plunger yodzaza ndi masika.
Inferential Flowmeter
Theturbine flowmeteramasintha kachitidwe ka makina kuti azitha kuwerenga mosavuta. monga gpm, lpm, etc. Gudumu la turbine limayikidwa mumsewu wamadzimadzi kuti madzi onse aziyenda mozungulira. Kenako madzi oyenda amasokoneza masamba a turbine, kutulutsa mphamvu pa tsamba ndikukankhira kozungulira. Kuthamanga kwa turbine kumayenderana ndi kuthamanga kwamadzimadzi pamene liwiro lozungulira lokhazikika lifika.
Electromagnetic Flowmeter
Themaginito flowmeter, wotchedwanso "magi mita"kapena"electromag", gwiritsani ntchito gawo la megnetic lomwe limagwiritsidwa ntchito ku chubu cha metering, chomwe chimapangitsa kusiyana komwe kungathe kutsatizana ndi kuthamanga kwa liwiro la perpendicular to flux mizere. kuchuluka kwa madzi kungathe kuzindikirika ndi mphamvu yamagetsi yomwe imachokera ku mafakitale okhudzana ndi zamadzimadzi zonyansa, zowononga kapena zowononga mwatsatanetsatane komanso durability,maginito oyenda mitaNthawi zambiri amagwiritsidwa ntchito pokonza madzi, kukonza mankhwala, komanso kupanga zakudya ndi zakumwa.
Anultrasonic otaya mitakuyeza kuthamanga kwa madzi ndi ultrasound kuwerengera kuchuluka kwa madzi. The otaya mita amatha kuyeza pafupifupi liwiro panjira ya anatulutsa mtengo wa ultrasound kudzera akupanga transduces. Werengerani kusiyana kwa nthawi yodutsa pakati pa ma ultrasound pansi kulowa kapena kutsutsana ndi komwe kumatuluka kapena yesani kusuntha pafupipafupi kutengera Doppler Effect. Kuphatikiza pa ma acoustic katundu wamadzimadzi, kutentha, kachulukidwe, mamasukidwe akayendedwe ndi ma particles oimitsidwa ndizinthu zomwe zimakhudzaUltra flow mita.
Avortex flow mitaimagwira ntchito pa mfundo yakuti "von Kármán vortex", kuyang'anira kuchuluka kwa madzimadzi poyesa kuchuluka kwa vortices. Kawirikawiri, mafupipafupi a vortices amafanana mwachindunji ndi mlingo wothamanga. Piezoelectric element mu detector imapanga chizindikiro chosinthira ndi ma frequency ofanana ndi vortex. Ndiye chizindikiro choterocho amaperekedwa kwa wanzeru otaya Totalizer kuti zina processing.
Makina opangira ma flowmeters
Miyero yabwino yosunthira imayesa kuchuluka kwamadzimadzi omwe amayenda muchombo ngati ndowa kapena wotchi yoyimitsa. Mtengo wothamanga ukhoza kuwerengedwa ndi chiŵerengero cha voliyumu ndi nthawi. Kudzaza ndi kuthira zidebe mosalekeza ndikofunikira kuti muyesedwe mosalekeza. Mamita a piston, ma oval gear metres ndi nuating disk mita zonse ndi zitsanzo zamamita abwino osamuka.
Kuyambira zosunthika mawotchi flowmeters kwambiri yeniyeni Coriolis ndi akupanga mamita, mtundu uliwonse ndi ogwirizana ndi zenizeni mafakitale amafuna. Kaya mukufunika kuthana ndi mpweya, zakumwa, kapena nthunzi, pali yankho lanu. Tengani sitepe yotsatira kuti muwongolere bwino makina anu pofunafuna chitsogozo cha akatswiri.Lumikizanani nafelero kuti mupeze mawu aulere, osachita chilichonse, ndipo tiyeni tikuthandizeni kupeza mita yabwino yoyendetsera ntchito yanu!
