Pressure gauge siphons anoshandiswa kuchengetedza gauji yekumanikidza kubva kune inopisa yekumanikidza midhiya senge steam uye zvakare kudzikisa mhedzisiro yekukurumidza kumanikidza kusimuka.Iyo yekumanikidza yepakati inoumba condensate uye inounganidzwa mukati mecoil kana pigtail chikamu cheiyo pressure gauge siphon.Iyo condensate inodzivirira iyo inopisa midhiya kuti isauye yakanangana neiyo yekumanikidza chiridzwa.Apo siphon inotanga kuiswa, inofanira kuzadzwa nemvura kana chero ipi zvayo yakakodzera yekuparadzanisa mvura.
