Metung a nibel

Aniang mumuna, ating lang aduang ampolias (glass vial) a tabas-sagin king balang pisisilipan (viewing point), at mas komplikadu lang gamitan deng nibel. Kanitang dekadang 1920, i Henry Ziemann, ing mitátag king w:Empire Level, inimbentu ne ing makabayung nibel a maki metung mung ampolias. Deting ampolyas, a mayayakit kareng keraklan a karaniwang nibel ngeni, atin lang tubong salamin a makabaluktut bagya at e laganas a sapak king likidu, a keraklan ‘spirit’ (ing aus da king ethanol, metung a uri ning alcohol)ania ating bulang lalto king tubo. Gagamitan de ing ethanol uling mababa ing kayang w:freezing point (temperatura ning pamagyelu]], −114 °C, at e magyelu neng marimla ing panaun. Keraklan, gagamitan do reng nibel bang ipakit nung pante ya pangakera (level) o pangatikdo (plumb) ing metung a patag o surface.

Deng aliwang nibel, agyu de muring pakit ing anggulu ning metung a patag pilatan ning pakera (horizontal) ampong patikdo (vertical). Ing simpling diling uri ning nibel, ya pin ing bull's eye level: metung a kasangkapan a mabilug at pante king lalam, nung nu atyu ing likidu king lalam ning lupang salamin a convex (makalual libutad) bagya, nung nu ya malinong mayayakit ing sentru. Papakit na ing pangapante ning metung a patag kareng aduang direksiun/nangan a mikukurus (perpendicular), kabang itang w:tubular level agyu na mung gawan iti king direksiun ning tubo. Saktu la angga king limang kayapulung libu ning pulgada (.0005) balang pulgada, at mas malagua lang basan uling iro/asul ing karelang kule. Nung kailangan yang gamitan a agiang baligtad ya ing metung a nibel, tubo yang tabas-barilis ing magagamit, imbes na tubong tabas-sagin. Uli na niti, pane yang ustu tabas ing babo nang patag a pangkilub (upper internal surface) nign tubo. Anti la kaniti tabas deng keraklan kareng makabayung nibel, uling ampolias a plastic ing gagamitan da imbes na salamin a baluktut.
