Makhalidwe a Open - Channel Flowmeter mu Weir kapena Flume

1. Kuyeza Kuyenda Kolondola​

• Mu thanki ya dziwe, ma flowmeter otseguka amapangidwa kuti ayesere kuchuluka kwa madzi molondola kwambiri. Nthawi zambiri amagwiritsa ntchito mfundo yoyezera mutu (mlingo wa madzi) pamwamba pa dziwe kapena kapangidwe ka flume. Mwachitsanzo, mu dziwe la V-notch, ubale pakati pa kuchuluka kwa madzi ndi kuchuluka kwa madzi umatsatira njira yodziwika bwino ya masamu. Poyesa molondola kuchuluka kwa madzi, flowmeter imatha kuwerengera kuchuluka kwa madzi molondola. Kulondola kungakhale mkati mwa magawo ochepa, zomwe ndizofunikira kwambiri pakugwiritsa ntchito monga kasamalidwe ka madzi, komwe deta yolondola ya madzi ndi yofunika kuti madzi agawidwe bwino komanso kuwunika.​

2. Kuyenerera Mitundu Yosiyanasiyana ya Weir ndi Flume​

• Ma flowmeter otseguka amatha kusinthasintha kwambiri ku mitundu yosiyanasiyana ya ma weir ndi ma flume. Kaya ndi weir wa rectangular, triangular weir, kapena Parshall flume, flowmeter ikhoza kukonzedwa kuti igwire ntchito bwino. Mitundu yosiyanasiyana ya weir ndi flume ili ndi mawonekedwe awoawo a hydraulic, ndipo open-channel flowmeter imatha kuyesedwa ndikukonzedwa kuti igwirizane ndi kusiyana kumeneku. Mwachitsanzo, flume ya Parshall nthawi zambiri imagwiritsidwa ntchito m'malo omwe flow rate imafunika kuyezedwa pamlingo waukulu. flowmeter yotseguka ikhoza kusinthidwa kuti iyese molondola flow kudzera mu Parshall flume, mosasamala kanthu kuti flow ili pamlingo wotsika kapena wapamwamba.​

3. Kukhazikitsa Kosasokoneza​

• Kuyika ma flowmeter otseguka m'matanki a weir nthawi zambiri sikusokoneza. Ambiri mwa ma flowmeter amenewa amagwiritsa ntchito masensa omwe amaikidwa pamwamba kapena pafupi ndi weir kapena flume, popanda kusokoneza kuyenda kwa madzi. Mwachitsanzo, masensa a ultrasound level amagwiritsidwa ntchito nthawi zambiri. Amayikidwa pamwamba pa madzi mu thanki ya weir ndipo amayesa mtunda wochokera pamwamba pa madzi. Njira yokhazikitsa yosasokoneza iyi imachepetsa kukhudzidwa kwa kuyenda kwa madzi mu thanki ya weir, komanso imapangitsa kuti njira yokhazikitsa ikhale yosavuta. Palibe chifukwa choyimitsa kuyenda kwa madzi panthawi yoyika, zomwe ndizosavuta kwambiri pamakina ogwirira ntchito mosalekeza monga malo oyeretsera madzi otayira.​

4. Kudalirika m'malo ovuta​

• Matanki a m'madzi nthawi zambiri amakhala m'malo akunja kapena m'mafakitale komwe zinthu zimakhala zovuta. Ma flowmeter otseguka amapangidwa kuti akhale odalirika m'malo otere. Nthawi zambiri amapangidwa ndi zinthu zolimba zomwe zimatha kupirira kukhudzana ndi madzi, chinyezi, ndi kutentha. Kuphatikiza apo, masensa omwe amagwiritsidwa ntchito mu flowmeters awa nthawi zambiri amatetezedwa ku zinthu zakunja monga magetsi. Mwachitsanzo, mu fakitale yotsukira madzi otayidwa, komwe kungakhale ndi zida zambiri zamagetsi zomwe zikugwira ntchito pafupi, flowmeter yotseguka imathabe kugwira ntchito bwino komanso molondola kuyeza kuyenda kwa madzi otayidwa mu thanki ya m'madzi.​

5. Kuyang'anira Patali ndi Kutumiza Deta​

• Ma flowmeter amakono otseguka m'matanki a weir ali ndi kuthekera kowunikira kutali komanso kutumiza deta. Amatha kulumikizidwa ku makina olamulira pakati pogwiritsa ntchito njira zolumikizirana za waya kapena zopanda zingwe. Izi zimathandiza ogwiritsa ntchito kuyang'anira kuchuluka kwa madzi mu thanki ya weir nthawi yeniyeni kuchokera kumalo akutali. Mwachitsanzo, mu makina othirira akuluakulu okhala ndi matanki ambiri a weir omwe amagawidwa pamalo ambiri, deta ya madzi kuchokera ku flowmeter iliyonse yotseguka imatha kutumizidwa ku chipinda chowongolera chapakati. Ogwiritsa ntchito amatha kusanthula detayo, kusintha makina ogawa madzi ngati pakufunika kutero, ndikuwonetsetsa kuti madzi akugwiritsidwa ntchito bwino.
