Kodi sensa ya flowmeter yolumikizira magetsi idzawonongeka ikagwiritsidwa ntchito poyesa mapaipi omwe ali ndi zinthu zowononga (monga asidi ndi alkali) kwa nthawi yayitali? Kodi nthawi yogwiritsira ntchito sensa ikugwirizana ndi zinthu zomwe zili mupaipiyo?

Sensa yolumikizira yokha siikhudzana mwachindunji ndi sing'anga. Chipinda chake nthawi zambiri chimapangidwa ndi chitsulo chosapanga dzimbiri cha 316L, PTFE (polytetrafluoroethylene), kapena pulasitiki ya ABS engineering, kotero nthawi zambiri sichidzawonongeka ndi sing'anga yowononga mkati mwa payipi. Komabe, dzimbiri ndi ukalamba wa zinthu za payipi zimakhudza mwachindunji moyo wa sensa ndi kulondola kwa muyeso:

• Ngati khoma lamkati la payipi likhala losalingana, lokhala ndi mamba, kapena lokhala ndi makulidwe osalingana a khoma chifukwa cha dzimbiri, lingayambitse kufalikira kwa liwiro la kuyenda mkati mwa payipi ndi kupatuka kwa njira yofalitsira ya ultrasound, motero kuonjezera zolakwika muyeso.
• Ngati khoma lakunja la payipi (pamwamba pa sensa) lachita dzimbiri kapena lili ndi khungu lotupa chifukwa cha dzimbiri la chilengedwe (monga chinyezi, mpweya wa mankhwala), zimachepetsa mphamvu yolumikizirana pakati pa sensa ndi payipi, zomwe zimapangitsa kuti zizindikiro zisakhazikike. Pakapita nthawi, izi zitha kuyambitsa kuwonongeka kwa sensa (chifukwa cha kusintha kwa kuthamanga mobwerezabwereza komwe kumafunika kuti kulumikizana kusagwire bwino ntchito).
