What is the difference between a spirit level and a level?

Level: It is a common measuring tool for measuring small angles. In the mechanical industry and instrument manufacturing, it is used to measure the angle of inclination relative to the horizontal position.

The flatness of the guide rail of the machine tool equipment.

and straightness, horizontal and vertical position of equipment installation, etc. According to the different shapes of the level, it can be divided into: universal level, cylindrical level, integrated level, mini level, camera level, frame level, ruler level; Press level.

The fixation method can be divided into: adjustable spirit level and non-adjustable level.

Level. It is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the leveling principle.

The main components are the telescope, the tube level (or compensator), the vertical axis, the base, the foot spiral. According to the structure, it is divided into micro-inclination level, automatic leveling level, laser level and digital level (also known as electronic level). According to the accuracy, it is divided into precision level and ordinary level.

As the name suggests, the level is used to measure the level of a certain surface, for example, the level can be placed on the table to measure whether the top surface of the table is horizontal, and the level of the plane is sometimes very important in engineering, for example, if the ground of a parking lot is not level, the car may slip if it is parked in it without applying the parking brake, and the consequences are very serious.

The level is used to ultra-flat, that is, to obtain the relative elevation of the measurement point, generally speaking, in the project is to control the construction elevation, for example, to build a building, the ground elevation on the second floor is meters, this can be measured with a level, if the measurement is not enough meters, it means that there is a problem in the construction, probably this is the meaning.

Feel free to ask!

A level is an instrument that measures the difference in height between points on the ground.

Leveling is to place a level between two points on the ground, observe the level scale erected on the two points, and calculate the height difference between the two points according to the readings on the scale.

The elevation of each point is determined station by station, usually from the origin of the level or any known elevation point, along the selected leveling route. Since the water level of different elevations is not parallel, and the elevation difference between the two points measured along different routes will be different, it is necessary to make necessary corrections according to the normal elevation system used in order to obtain the correct elevation when collating the results of national level measurements.

A level is a surveying and mapping tool, usually one person holds a ruler and one person looks at the ruler readings through the level. The relative topographic height of the ruler is obtained by the difference in the readings of the ruler. In a survey, the position of the level is fixed.

Elevation is also the level of height.

Level shuǐpíngyí

An instrument for determining the water level. It consists of a frame and a curved glass tube filled with ether or alcohol, in which air bubbles are left and the bubbles are always at the highest point of the tube. When the spirit level is in the horizontal position, the position of the bubble is in the middle of the scale on the tube. Also called leveler.

An instrument that uses a horizontal line of sight to directly determine the height difference between two points on the earth's surface is mainly composed of a telescope and a spirit level.

1. Definitions. Level: It is a common measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the guide rail of machine tool equipment, the horizontal position and vertical position of equipment installation, etc.

A level is an instrument that establishes a horizontal line of sight to determine the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the leveling principle.

2. The principle is different.

The leveling tube of the level is made of glass, the inner wall of the leveling tube is a curved surface with a certain radius of curvature, the tube is filled with liquid, when the level is tilted, the bubbles in the level tube move to the raised end of the level, so as to determine the position of the level.

The larger the radius of curvature of the inner wall of the leveling tube, the higher the resolution, and the smaller the radius of curvature, the lower the resolution, so the radius of curvature of the leveling tube determines the accuracy of the level. The spirit level is mainly used to check the flatness, straightness, verticality and horizontal position of equipment installation of various machine tools and workpieces.

When the level is operating, the instrument is roughly leveled with a round level, and then with the help of a slight tilt spiral before each reading, the level is pitched in the vertical plane until the level bubble is accurately centered to make the line of sight level.

Compared with the ordinary level, the micro-tilting precision level is small, the sensitivity is high, the magnification of the telescope is large, the brightness is strong, and the instrument structure is firm, especially the connection between the telescope and the tube level is firm, equipped with an optical micrometer, and equipped with a precision level, so as to improve the reading accuracy.

3. Classification. The level is divided into: universal level, cylindrical level, integrated level, mini level, camera level, frame level, ruler level.

Level: According to the structure, it is divided into micro-tilt level, automatic leveling level, laser level and digital level (also known as electronic level). According to the accuracy, it is divided into precision level and ordinary level.

Hello dear, <>

The difference lies in the structure of the instrument, the principle of measurement and the principle of operation method, especially the difference in accuracy. Ordinary level is an optical instrument, such as a micro-tilt level is mainly composed of three parts: a telescope, a level and a base, the telescope can provide a horizontal line of sight, and can read the reading on the level; The level is used to indicate whether the instrument is in a horizontal position; The pedestal is used to support the upper part of the instrument and attach the tripod. The electronic level is an electronic instrument that uses image processing technology to automatically read the height difference and distance, and automatically records data and processes the results.
