Abstract

Electronic spirit level for measurement of inclination from 0 to 360 degrees. In a circular tube being bent into a round ring and only partially filled with electrically conducting spirit along the entire perimeter there is placed a resistor in form of wire with equally varying sectional area. Therefore the resistance of the system depends upon the position of the air bubble. The resistance is measured and calculated into angular degrees and displayed upon the screen. By that the housing can be more or less filled with spirit. At the outer side can be tightly one beside the other placed coils, where each of coils is separately connected to the measuring instrument. When upon the wire in the inside the alternating electric voltage is connected, in all coils electric voltage shall be induced. There where the air bubble is placed also the induced voltage in the coils is different. By successive measurements in all coils it can be precisely ascertained where at the moment the air bubble is situated. The air bubble and the inner wire can be substituted by a small metallic ball.
