Magnetic Level Gauge GB2506-89


The Magnetic Level Gauge GB2506-89 refers to a specific type of level gauge that complies with the GB2506-89 standard, which is a Chinese national standard for magnetic level gauges. This standard outlines the specifications and requirements for the design, construction, and performance of magnetic level gauges used in industrial applications.

A magnetic level gauge is a device used to measure the level of liquids or slurries in tanks or vessels. It utilizes the principle of magnetic coupling between a float and an external indicator to provide a visual indication of the fluid level. The float, typically containing a permanent magnet, rises and falls with the liquid level, while the indicator, located outside the tank or vessel, displays the corresponding level.

The GB2506-89 standard specifically defines the technical parameters, materials, dimensions, and manufacturing tolerances for magnetic level gauges. It ensures consistency and quality in the production and application of these gauges in China.
