Level bubbles

Level bubbles

A bubble level is an instrument used across many industries. Designed to indicate whether a surface is horizontal or vertical, it is an essential component in manufacturing and engineering.

These components are characterised by a hollow body containing a fluid with a gas bubble. The bubble is used to control the levelling of any object. The position of the gas bubble in the fluid shows the angle and the direction in which the object is inclined with respect to the horizontal plane. The hollow body—containing the contrast fluid—and the gas bubble floating in the upper part are always at the highest point.

Made from high quality stainless steel, technopolymer, aluminium, and brass, our level bubbles are available in the following finishes:

  • anodised aluminium body natural colour, with smooth reference surface
  • anodised aluminium body black colour, with smooth reference surface
  • anodised aluminium body natural colour, with threaded pin
  • anodised aluminium body black colour, with threaded pin

Alongside "cylindrical" levels for unidirectional measurements, our bull's eye levels are available for bidirectional measurements. These elements allow for the levelling of planes in two dimensions rather than one. The monodirectional bull's eye levels are available with rear or bottom insulation plaster and are ideal for detecting the inclination angle in a direction along the axis of the level. The bidirectional spirit levels simultaneously detect the tilt angle and the angular position of a floor.

Our selection is available with adjusting pin, mounting flange, or holes for screw mounting.

Within our range of Elesa level bubbles we also provide an adjusting plate that can be used in combination with our bull’s eye components. The adjusting pin allows the adjustment of the bubble acting as a pivot point. The screws can be tightened to achieve the desired adjustment with respect to the mounting surface until obtaining a perfect positioning of the bubble in the circular marking of the window.

Whatever you need a spirit level for, you will find the essential components in the Elesa catalogue.
