Piezometer
Ifa tapping inogadzirwa mumuganhu wepamusoro uye yakaringana yakareba chubhu yakabatana, iyo mvura inokwira muchubhu kusvika yakaenzana nemhepo yemhepo. Dzvinyiriro iri mumutumbi mukuru wemvura inomiririrwa nehupamhi hwakatwasuka hwembiru yemvura. Zviripachena, mudziyo wacho wakakodzera chete kune zvine mwero kudzvanywa, zvikasadaro mvura inokwira zvakanyanya mupiezometer chubhu kuitira kuyerwa kuri nyore.

Kana iyo mvura ichiyerera, iyo piezometer tapping haifanire kudarika 3 mm dhayamita uye inofanira kunge yakanyungudutswa nepamusoro pemuganhu. Nekunyanya kurongeka, piezometer ring inogona kuiswa.Iyi ine annular chamber yakatenderedza pombi uye yakabatana nayo nenhamba yakawanda yakaenzana tappings.
Manometer
Manometer Musimboti wakafanana newakatsanangurwa pamusoro, asi matambudziko ane chekuita nechubhu yakareba zvakanyanyisa anokundwa nekuisa U-chubhu ine mvura isingagoneki. Mercury(specific gravity 13,6) ndiyo manometer fluid inowanzo shandiswa kuyera dzvinyiriro yemvura. Iyo gauge pressure p mupombi inopiwa ne
