Icho chiridzwa chinofanira kuverengerwa mukati memba isati yaiswa kuti ive nechokwadi chekuita kwakajairika.
General kufunga
1. Iyo yakavhurika chiteshi flowmeter inofanirwa kuongororwa mukati memba isati yaiswa kutisimbisa kuita kwakajairika kwemamita.
2. Rongedza iyo ultrasonic probe yeyakavhurika chiteshi flowmeter ine madziro seyakamira sezvinokwanisika kuve nechokwadi kuti inoyerwa.
3. Zvinoenderana neiyo label pazasi terminal, batanidza probe kune muenzi, uyemaererano nemagetsi ekupa label, simba mita nemazvo.
4. Iyo yakavhurika chiteshi flowmeter inotanga kuratidza yekutanga sikirini, uye ipapo inoratidza iyopeji huru yekuyera.Chiratidzo chiri pakona yepamusoro yekurudyi yechiratidziro
kupenya uye kuverenga kwakagadzikana, zvichiratidza kuti kutaurirana pakati pehost uye probe ndeye yakajairika.
5. Bata bhari yekufambisa yemamita, mita inogona kuchinja kune imwe chiyeroruzivo mapeji (chinhambwe, tembiricha, zvazvino, nhanho yemvura), uye iwe unogona zvakare
ona chaiyo-nguva data mafambiro uye nhoroondo data rekodhi.
6. Zvishoma nezvishoma fambisa probe, kukosha kweyero yemvura uye kukosha kwechinhambwe kunoratidzwa nemita inofanira kuchinja saizvozvo.Kana uchifamba mukati mechinhambwe chipfupi (1m), kumhanya hakufanirwe kudarika 0.1m/s.Kune hwindo rekuona mukati mechiridzwa, uye chiridzwa chinotarirwa kupfuurahwindo rekuona rinoda nguva yekutonga ingangoita 5s.Hwindo rezingageji pazasi 10m inowanzo ± 0.5m, uye hwindo regeji repamusoro pamusoro pe10m.iri ±1.2m.Nekuda kwekuvapo kwehwindo rekuona, mita yacho dzimwe nguvaita zvikanganiso kana chinhambwe chinenge 1/2 nguva chinhambwe kubva kure kuenda kunepedyo.Iko kungoerekana kwachinja kwechinhambwe kazhinji hakupo mune chaiyokuyerwa nzira.
7. Muzvirongwa zvekutanga, shandura weir / flume modhi uye urefu hwekuisa, chengetedza uyekubuda, kukosha kwekuyerera kunoratidzwa nemamita kuchachinja, uye ona kuti iyokuyerera kwemamita kuri kuwedzera.
8. Shandisa multimeter kuyera DC4-20mA ikozvino kubuda, ikozvino kubudanguva dzose inopindirana nekukosha kwekuyerera kwepakarepo.
9. Shandura mamiriro ekushanda kweiyo relay uye kukosha kwakatarwa kwenzvimbo yekuita, uye shandisamultimeter yekutarisa kana relay yakanyatso kunonoka kuita.
10. Batanidza nekombuta inotambira kuti uedze iyo RS485 yekutaurirana basa remudziyo .
