Chiyero che ultrasonic flow meter chinoshandiswa zvakanyanya pakuyera kuyerera kwemvura chisingapindi mvura. Chichishandisa tekinoroji yepamusoro ye ultrasonic, chinoyera kuyerera kwemvura mumapaipi akavharwa nekuongorora musiyano wenguva yemasaini e ultrasonic anotumirwa kumusoro nekudzika. Dhizaini yayo itsva uye mabhenefiti ayo anoshanda zvinoita kuti ive mhinduro inoshandiswa mumaindasitiri akasiyana-siyana. Pazasi, tinoongorora zvinhu zvakakosha zvechishandiso ichi chinoshandiswa zvakasiyana-siyana:
1. Dhizaini Isina Kupindira
Chimwe chezvinhu zvinonyanya kukosha pama clamp-on ultrasonic flow meters ndechekuti haapindiri. Mamita aya akaiswa kunze kwepombi, asingade kusangana nemvura yacho. Dhizaini iyi:
• Inobvisa kudiwa kwekucheka kana kugadzirisa pombi.
• Inodzivirira kusvibiswa, zvichiita kuti ive yakakodzera kushandiswa kwehutsanana uye kwakaoma senge chikafu, zvinwiwa, uye mishonga.
• Inobvumira kuiswa pasina nguva yekudzima system kana kukanganiswa kwemaitiro.
3. Kuyera Kwakarurama Uye Kwakavimbika
Nheyo yekufamba kwenguva inoita kuti kuyerera kuenderere zvakanaka, kazhinji zvichiita kuti kuenderere mberi nekufamba kwemvura kuve kwakarurama kwe±0.5% kana kupfuura. Inoyera musiyano wenguva dzekufamba kwemhepo dzinofamba nekufamba kwemvura uye dzichipesana nekuyerera kwayo. Zvinhu zvinobatsira pakujeka kwayo zvinosanganisira:
• Kugadziriswa kwechiratidzo kwepamusoro-soro kuti kugadzirise mamiriro ekuyerera kwemhepo ane kusagadzikana.
• Kukwanisa kuyera huwandu hwakasiyana hwemafambiro emvura.
• Kuenderana nezvinwiwa zvakachena uye zvinwiwa zvakasvibiswa zvishoma, chero bedzi huwandu hwekusvibiswa hwakaderera.
4. Mhando dzakasiyana dzemashandisirwo
Mamita aya akakodzera kushandiswa kwakasiyana-siyana, sezvo achigona kuyera mhando dzakasiyana dzezvinwiwa, zvinosanganisira:
• Mvura (yakacheneswa, isina kucheneswa, kana kuti isina tsvina).
• Makemikoro.
• Mafuta.
• Zvimwe zvinwiwa zvisina kusimba.
Kuchinjika kwavo kunosvika pakukwanisa kwavo kushanda nezvinhu zvakasiyana-siyana zvepombi zvakaita sesimbi, PVC, nezvinhu zvakasanganiswa, uye nepamadhayamita akasiyana-siyana epombi.
5. Kuisa uye Kugadzirisa Zviri Nyore
Dhizaini ye clamp-on inoita kuti kuisa kuve nyore, sezvo pasina chikonzero chekugadzirisa mapaipi kana kudzima mashandiro. Kugadzirisa kuri nyorewo:
• Kusafamba kwezvikamu kunoreva kuti kusakara nekupwanyika kwakaderera.
• Masensa anoramba ari kunze, zvichideredza njodzi yekusvibiswa, ngura, kana kukweshwa.
Izvi zvinoderedza mitengo yekushanda uye nguva yekushanda kwemudziyo mukati mehupenyu hwese.
6. Sarudzo Dzinotakurika uye Dzakagadziriswa
Mamita ekuyerera kwemagetsi emuchina wetransit-time anouya muchimiro chinotakurika uye chakagadzirwa, achienderana nezvinodiwa zvakasiyana:
• Mamita Ekuyerera Anotakurika: Akareruka uye madiki, akakodzera kuiswa kwenguva pfupi kana zvinangwa zvekuongorora.
• Mamita Ekufamba Akagadziriswa: Kuiswa kwechigarire kwekutarisa kuyerera kwemvura nguva dzose mumabasa akakosha.
7. Kuyera Madivi Aviri
Chinhu chakakosha che transit-time ultrasonic flow meters kugona kwavo kuyera flow munzira dzese dziri mbiri. Izvi zvinoita kuti vakwanise kushandiswa munzvimbo dzakasiyana siyana uko flow reversal inogona kuitika, senge mu hydraulic systems kana bidirectional pumping processes.
8. Kuburitswa Kwedata Rakadzama uye Kutaurirana
Mamita ekuyerera kwemvura emazuva ano ekufamba kwenguva ane hunyanzvi hwepamusoro hwekutaurirana, senge:
• Sarudzo dzemagetsi edhijitari uye analog (semuenzaniso, 4-20 mA, pulse, kana Modbus).
• Kuchengeta data kuti riongororwe kwenguva refu.
• Kubatanidzwa neSCADA nedzimwe nzira dzekutarisa.
