3. Ka'idar aiki

Lokacin da aka sanya daidaitaccen rufin mai watsawa a wani wuri a cikin ruwa, matsin lamba na firikwensin ta hanyar bututun gas shine:

P = 9.807ρH + Po inda P - na'urar firikwensin ta ji matsin lamba na kPa ρ - yawan matakin ruwa, na g / cm3

H - tsawon ruwa da za a auna, naúrar mPo - matsin lamba a kan ruwa, naúrar kPa

Idan na'urar firikwensin ta baya tana haɗi da saman ruwa, to, PO shine sifili, don haka H daidai ne da 0.102P / ρ, ta zama PO daidai ne da sifili, don haka H daidai ne da 0.102P / ρ, mai watsawa ya canza siginar matsin lamba da aka ji zuwa siginar lantarki, wannan siginar daidai ne da tsawon ruwa.

Lura: kwantena na ruwa da aka gwada dole ne ya shiga cikin yanayi, wato, yana buɗewa, ba za a iya rufewa ba, in ba haka ba sakamakon ma'ana ba ne.
