Umgomo wokusebenza wesikhathi sokuthutha
Isimiso Sokukala:
IIsikhathi sezokuthuthaIsimiso Sokuxhumanisa sisebenzisa iqiniso lokuthi isikhathi sokundiza kwesignali ye-ultrasonic ithintwa isivinini sokugeleza kwendawo yenethiwekhi.Njengombhukudi owela umfula ogelezayo, isignali ye-ultrasonic ihamba kancane ikhuphuka nomfula.
EyethuTF1100 ultrasonic flow metressebenza ngokwalesi simiso se-transit-lime:
Vf = Kdt/TL
Kuphi:
Isivinini se-VcFlow
K: Njalo
dt: Umehluko ngesikhathi sokundiza
I-TL: Isikhathi Sokuhamba Esimaphakathi
Lapho imitha yokugeleza isebenza, ama-transducer amabili adlulisa futhi athole amasignali e-ultrasonic akhuliswa ugongolo oluningi oluhamba luqale phansi nomfula bese lukhuphuka nomfula.Ngenxa yokuthi umsindo omkhulu uhamba ngokushesha uye phansi kunomfula, kuzoba nomehluko wesikhathi sokundiza (dt).Uma ukugeleza kumile, umehluko wesikhathi (dt) unguziro.Ngakho-ke, inqobo nje uma sazi isikhathi sokundiza kokubili phansi nomfula, singakwazi ukuthola umehluko wesikhathi, bese kuba isivinini sokugeleza (Vf) sisebenzisa ifomula elandelayo.
