ABSTRACT:
A level vial includes a pair of elongated vessels, each having a top open end, a bottom open end and a transparent tube portion having a flat side wall extending between the top open end and the bottom open end. A flexible elongated pipe has two ends respectively connected to the bottom open end of the elongated vessels to communicate with the transparent tube portion so as to contain water therein. The transparent tube portion of the elongated vessels may be selectively vented with the ambient environment. A float restraining member is fixed to and extends inwardly from an inner wall surface of the transparent tube portion of each of the elongated vessels. The float restraining member is disposed adjacent to the top open end of the elongated vessel and defines an axial through hole. A floating article is provided in the transparent tube portion of each of the elongated vessels inwardly of the float restraining member. The floating article blocks the axial through hole of the float restraining member when water inside the transparent tube portion rises to the vicinity of the top open end of the elongated vessel.
