Mitundu Yodziwika ya Mamita a Madzi ndi Makhalidwe Awo

Miyezo yamadzimadziNdi zida zofunika kwambiri zoyezera zomwe zimagwiritsidwa ntchito kuzindikira, kuwonetsa ndikuwongolera kutalika kwa madzi mkati mwa matanki, maiwe ndi mapaipi. Mfundo zosiyanasiyana zogwirira ntchito ndi kapangidwe kake zimapanga magulu angapo a ma level gauges, iliyonse yoyenera malo apadera, kutentha, kuthamanga ndi mafakitale. Mitundu yayikulu ikuphatikizapo ma buoy level mita, ma radar level transmitters, ma ultrasonic level sensors, ma magnetic flap level gauges, ma pressure-type level transmitters ndi capacitance level mita.

Ma gauge a maginito flap level ndi amodzi mwa zida zowonetsera zomwe zimagwiritsidwa ntchito kwambiri pamalopo. Amagwira ntchito potengera kuyandama ndi kulumikizana kwa maginito. Choyandama cha maginito mkati mwa chubu choyezera chimakwera ndikutsika ndi mulingo wamadzimadzi, ndikuyendetsa mapepala otembenuza maginito amitundu iwiri pa chizindikiro chakunja kuti atembenuke ndikuwonetsa kutalika kwamadzimadzi nthawi yeniyeni. Safuna magetsi, ali ndi kuwerenga kwachilengedwe, ndipo amatha kukhala ndi ma switch otulutsa chizindikiro chakutali. Ma gauge awa amakwanira zakumwa zoyera zosakhuthala monga madzi, mafuta ndi mankhwala opepuka, ndipo nthawi zambiri amaikidwa m'matanki osungiramo zinthu ndi m'madziwe oyeretsera madzi.

Miyeso ya mpira woyandama imagwiritsa ntchito mapangidwe oyandama a makina. Mpira woyandama umatsatira kusintha kwa pamwamba pa madzi ndipo umayendetsa ndodo zolumikizira kapena zotsutsana zamkati kuti zisinthe kutalika kwa madzi kukhala zizindikiro zamagetsi. Zosavuta komanso zotsika mtengo, ndi zabwino kwambiri pa matanki wamba ndi mafakitale wamba omwe safunidwa kwambiri. Komabe, mapangidwe a makina amatha kugwedezeka akamagwira ntchito ndi zakumwa zokhuthala kapena madzi okhala ndi matope.

Ma ultrasound level mitaKudalira kuwunikira kwa mafunde a phokoso. Chofufuzira chimatulutsa ma pulse a ultrasound kupita pamwamba pa madzi; makinawo amawerengera mtunda polemba nthawi yomwe ma echo amatenga kuti abwerere. Kuyeza kosakhudzana ndi madzi kumapewa kukhudzana mwachindunji ndi madzi, kuchotsa dzimbiri ndi zoopsa zotsekeka. Zimagwirizana ndi madzi oyera, zimbudzi ndi mankhwala osasinthasintha. Komabe nthunzi yochuluka, thovu kapena fumbi lolemera zidzafooketsa zizindikiro za ultrasound ndikuchepetsa kulondola kwa kuyeza.

Ma transmitter a radar level amatumiza zizindikiro za ma microwave zomwe zimawala kwambiri kuti ziwonetse pamwamba pa madzi. Ma microwave amalowa mu nthunzi, thovu ndi fumbi popanda kusokonezedwa, kupereka muyeso wokhazikika wolondola kwambiri pansi pa kutentha kwakukulu, kuthamanga kwambiri komanso mikhalidwe yosinthasintha. Amagwiritsidwa ntchito kwambiri m'ma kettle a chemical reaction, matanki osungira mafuta ndi malo osungiramo mafakitale otentha kwambiri, omwe amaonedwa kuti ndi chisankho chabwino kwambiri pamikhalidwe yovuta yogwirira ntchito.

Mtundu wa kupanikizikazotumizira za mulingoMuyeze kuchuluka kwa madzi kudzera mu mphamvu ya hydrostatic. Sensa yoyikidwa pansi pa thanki imasintha mphamvu ya madzi kukhala zizindikiro zamagetsi za 4-20mA. Mtengo wotsika komanso kuyika kosavuta kumapangitsa kuti zikhale zoyenera kwambiri maiwe otseguka, matanki a zinyalala pansi pa nthaka ndi ntchito zothirira. Sizingagwiritsidwe ntchito pa matanki otsekedwa okhala ndi mphamvu ya pamwamba yosinthasintha.

Mamita a capacitance level amazindikira kutalika kwa madzi kudzera mu kusintha kwa capacitance pakati pa ma electrode. Amasinthasintha kuti agwirizane ndi zolumikizira zokhuthala, slurry ndi mankhwala owononga, ndipo amathandizira muyeso wopitilira wa level komanso alamu ya point level. Kagwiridwe kawo ka ntchito kamakhudzidwa mosavuta ndi kusinthasintha kosalekeza kwa dielectric yamadzimadzi.

Mtundu uliwonse wamita yoyezera mulingoIli ndi mphamvu ndi zopinga zake. Makampani amafunika kusankha zida zofanana malinga ndi kukhuthala kwapakati, kuwononga, kutseka thanki, kutentha ndi kulondola kuti akwaniritse kuyang'anira mulingo wamadzimadzi mokhazikika komanso modalirika.
