1、 Overview of Welded Glass Plate Liquid Level Gauge

The welded glass plate level gauge is produced according to the original Ministry of Chemical Industry HG5-1364-1370-80 standards and is suitable for directly indicating the liquid level of various media in towers, tanks, tanks, boxes, and other containers. There are safety steel balls installed inside the upper and lower valves of the instrument. When the glass plate is accidentally damaged, the steel balls can automatically close the liquid flow channel under the pressure inside the container to prevent the liquid from continuing to flow out.
　　
2、 Characteristics of Welded Glass Plate Liquid Level Gauge

● Direct reading, accurate reading, reliable
● Simple structure and easy maintenance
● Safe and durable to use

3、 Structural principle of welded glass plate level gauge

According to the principle of connectivity, the liquid level of the medium in the container is led to the external glass level gauge, and the actual height of the liquid level in the container is directly displayed through transparent glass.
The sealing packing of the instrument valve stem adopts flexible graphite pressure ring, which has reliable sealing performance.
