Shigar da Bar Level Mai watsawa
I. Bayani
YY338 shigar da sandu-irin matakin watsawa ne biyu waya, 4 ~ 20MADC fitarwa, 24VDC DC samar da wutar lantarki, tare da kafofin watsa labarai lamba sassa ne duk bakin karfe,(Musamman lalata kafofin watsa labarai za a iya yi a cikin tetrafluoride kayan)Amfani ne sosai m, yadu ake amfani da shi a kan tsari iko da kuma ma'auni na ruwa matakin a man fetur, sinadarai, karfe, ruwa, wutar lantarki, abinci, magunguna, muhalli sa ido da sauran masana'antu.
2. Ka'idar aiki (Ka'idar auna matsin lamba)
Lokacin da matakin mai watsawa ya shiga cikin wani zurfin ruwa da aka auna, matsin lamba da na'urar firikwensin ke fuskantar ruwa shine: Ρ = ρ.g.H + Po formula:
P: Matsin lamba daga mai watsawa
ρ: yawan ruwa da aka gwada
g: Na gida gravity hanzarta
Po: matsin lamba a kan ruwa
H: zurfin mai watsawa sanya ruwa
A lokaci guda, matsin lamba na wani zurfin ruwa yana jawo hankalin matsin lamba mai kyau na firikwensin, sa'an nan kuma haɗa matsin lamba na yanayi a kan ruwa da matsin lamba mai kyau na firikwensin don daidaita Po a bayan firikwensin, don sa firikwensin ya auna matsin lamba a matsayin: ρ.g.H, a bayyane yake, ta hanyar auna matsin lamba P, za a iya samun zurfin matakin ruwa.
