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 = 9.807pH + Po

inda P - matsin lamba da na'urar firikwensin ta ji, naúrar kPa

P - Level yawa, karatun g / cm³

H - tsawon ruwa da za a auna, m

Po - matsin lamba a kan ruwa, naúrar kPa

Idan na'urar firikwensin ta baya ta haɗa da saman ruwa, to, Po sifili ne, don haka H daidai ne da 0.102P / p, mai watsawa ya canza siginar matsin lamba da aka ji zuwa siginar lantarki, wanda ya dace da tsawon ruwa.
