Problems solved by technology

[0002] The traditional spirit level is a straightedge bubble type with a small measurement range, and can only distinguish a small range of places at the same height: some people also invented a four-point level. When using a four-point level, three points are often overhead and one point is not recognized. big mistakes

Abstract

The invention discloses a T-type platform three-point level meter with liquid metal as a working medium. The liquid metal is used as the working medium; the level meter comprises the following components: a T-type platform, three reference points for forming a regular triangle or a right angled triangle on the platform, three metal vertical tubes with long grooves and scales, and three transparent tubes which are connected by a tee and contain liquid metal; the level meter is used for accurately determining related level degrees.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a T-shaped platform three-point level with liquid metal as a working medium. Background technique [0002] The traditional spirit level is a straightedge bubble type with a small measurement range, and can only distinguish a small range of places at the same height: some people also invented a four-point level. When using a four-point level, three points are often overhead and one point is not recognized. If it is found, it will cause a big mistake. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention is achieved in this way: the T-shaped platform three-point level gauge with liquid metal as the working medium uses the liquid metal as the working medium, and the T-shaped platform 1 and the three-point level that constitutes an equilateral triangle or a right-angled triangle are formed on the platform. A re...
