Zinthu Zomwe Zimakhudza Kugwira Ntchito kwa Ma Ultrasonic Water Meters

1. Zinthu Zokhudzana ndi Madzi

Mabomba a Gasi M'madzi

Ma thovu a gasi ndi vuto lofala m'makina operekera madzi.kuyenda kwa madzikudzera m'mapaipi, makamaka pamene kuthamanga kwa madzi kumasintha kapena pali gwero la mpweya wosungunuka, thovu la mpweya limatha kupangidwa. Mafunde a ultrasonic amafalikira kudzera m'madzi pogwedeza mamolekyu amadzi. Thovu la mpweya, lomwe limakhala ndi mphamvu yosiyana kwambiri ya acoustic impedance poyerekeza ndi madzi, limagwira ntchito ngati zowunikira zamphamvu komanso zobalalitsira mafunde a ultrasound. Pamene chizindikiro cha ultrasound chikukumana ndi thovu la mpweya, gawo lalikulu la mphamvu limabwereranso msanga kapena limafalikira mbali zosiyanasiyana. Izi zimasokoneza kufalikira kwabwinobwino kwa chizindikiro cha ultrasound pakati pa chotumizira ndi cholandirira mu mita yamadzi. Zotsatira zake, mita ikhoza kutanthauzira molakwika chizindikirocho, zomwe zimapangitsa kuti pakhale kuwerengera kolakwika kwa kuchuluka kwa madzi komanso kuwerenga kolakwika kwa madzi.

Dothi ndi Zonyansa

Pakapita nthawi, mapaipi amadzi amasonkhanitsa matope, dzimbiri, ndi zina zonyansa. Zinthuzi zimatha kukhazikika pakhoma lamkati la mapaipi ndipo, pankhani ya zoyezera madzi zamagetsi, zimatha kuphimba pamwamba pa choyezera madzi zamagetsi. Dothi ndi zinyalala pa choyezera madzi zamagetsi zimatha kuchepetsa chizindikiro cha ultrasound. Chizindikirocho chiyenera kudutsa mu gawo ili la zodetsa zisanafike m'madzi, ndipo panthawiyi, mphamvu yake imachepa. Kuphatikiza apo, malo ozungulira omwe amapangidwa ndi matope amatha kupangitsa mafunde a ultrasound kufalikira, zomwe zimapangitsa kuti zikhale zovuta kuti choyezera chizindikire molondola nthawi - ya - kuuluka kapena kusintha kwa Doppler (kutengera mtundu wachoyezera madzi cha ultrasonicKusokoneza kumeneku ndi chizindikiro kumabweretsa zolakwika poyesa liwiro la madzi, zomwe pamapeto pake zimapangitsa kuti pakhale miyeso yolakwika ya kuchuluka kwa madzi.

2. Zinthu zokhudzana ndi kukhazikitsa

Kusankha Gawo la Chitoliro Cholakwika

Malo achoyezera madzi cha ultrasonicKukhazikitsa mkati mwa netiweki ya mapaipi ndikofunikira kwambiri. Ngati mita yayikidwa mu gawo la chitoliro chomwe chili ndi mawonekedwe osagwirizana a kuyenda, monga pafupi ndi kupindika, chigongono, kapena valavu, kuyenda kwa madzi kumakhala kovutirapo. Mu kuyenda kovutirapo, liwiro la madzi limasiyana kwambiri kudutsa gawo lopingasa la chitoliro. Ma ultrasound water meter amapangidwira kuyeza liwiro lapakati la kuyenda kwa madzi. Komabe, akayikidwa pamalo ovutirapo, liwiro loyezedwa silingaimire kuyenda konse mu chitoliro. Mwachitsanzo, mu kupindika kwa chitoliro, madzi pafupi ndi khoma lakunja la kupindika amayenda mofulumira kuposa pafupi ndi khoma lamkati. Ngati ultrasound meter imayeza liwiro pamalo omwe amakhudzidwa kwambiri ndi madzi akunja othamanga mofulumira, idzayerekeza kuchuluka kwa kuyenda konse.

Kusakhazikika kwa Sensor Kolakwika

Kulinganiza bwino masensa a ultrasonic ndikofunikira kuti muyeze molondola. Masensa omwe ali mu chipangizo choyezera madzi cha ultrasonic ayenera kulumikizidwa bwino kuti atsimikizire kuti chizindikiro cha ultrasound chikuyenda m'madzi munjira yodziwikiratu. Ngati masensawo asokonekera, chizindikirocho sichingafike pa sensa yolandirayo molondola. Ngakhale kusokonekera pang'ono kungayambitse mafunde a ultrasound kuyenda njira yayitali kapena yovuta kwambiri kudzera m'madzi, zomwe zingayambitse zolakwika pakuyesa nthawi - ya - kuuluka kapena kusintha kwa Doppler. Cholakwika ichi choyambitsidwa ndi kusokonekera chingasonkhanitsidwe pakapita nthawi ndikupangitsa kuti pakhale kusiyana kwakukulu pakuwerengera kwa madzi.

3. Zinthu Zachilengedwe

Kusintha kwa kutentha

Kutentha kumakhudza kwambiri momwe ma ultrasound water meter amagwirira ntchito. Liwiro la phokoso m'madzi limagwirizana mwachindunji ndi kutentha kwake. Pamene kutentha kwa madzi kukusintha, liwiro lomwe mafunde a ultrasound amadutsamo limasinthanso. Ma ultrasound water meter amadalira chidziwitso cholondola cha liwiro la phokoso m'madzi kuti awerengere kuchuluka kwa madzi. Ngati njira yolipirira kutentha mu meter sinalinganizidwe bwino kapena ikulephera kufotokozera kusintha kwa kutentha mwachangu, meter imawerengera kuchuluka kwa madzi kutengera mtengo wolakwika wa liwiro la mawu. Mwachitsanzo, ngati kutentha kwa madzi kukukwera, liwiro la phokoso m'madzi limawonjezekanso. Ngati meter sikusintha kuti igwirizane ndi kuwonjezeka kumeneku, idzachepetsa kuchuluka kwa madzi chifukwa imaganiza kuti liwiro la mawu ndi lotsika.

Kusokoneza kwa Magetsi

M'malo amakono, pali magwero ambiri a kusokoneza kwa ma electromagnetic (EMI). Ma ultrasound water meter, omwe amagwiritsa ntchito zigawo zamagetsi popanga ndikulandira ma ultrasound signals, amatha kukhudzidwa ndi EMI. Magwero a EMI amatha kuphatikizapo mizere yamagetsi yapafupi, ma motor amagetsi, ndi ma radio transmitters. EMI imatha kusokoneza ma signal amagetsi omwe ali mkati mwa meter yamadzi, zomwe zimapangitsa phokoso mu ultrasound signal yolandiridwa. Phokoso ili likhoza kusokoneza signal ndikupangitsa kuti chipangizo choyezera chizindikiro cha meter chikhale chovuta kuzindikira molondola makhalidwe oyenera a ultrasound poyezera kuyenda kwa madzi. Zotsatira zake, meter yamadzi ikhoza kupanga ma read olakwika chifukwa cha kusokoneza kuchokera ku ma electromagnetic fields akunja.

Pomaliza, kuonetsetsa kuti ntchito yolondola yazoyezera madzi za ultrasonic, ndikofunikira kuganizira ndi kuthana ndi zinthu izi zokhudzana ndi madzi, kukhazikitsa, ndi chilengedwe. Pochita izi, miyeso yodalirika yogwiritsira ntchito madzi ingapezeke, zomwe ndizofunikira kwambiri pakuwongolera bwino madzi ndi njira zolipirira.
