What Are the Industry Applications of Glass Plate Level Gauges

The glass plate level gauge is a standard liquid level measurement device that is widely used in various industrial fields, including the chemical industry, petroleum, pharmaceuticals, and food. This article will introduce how glass plate level gauges work, their main applications, and their advantages in industrial applications.

What Are the Industry Applications of Glass Plate Level Gauges

1. Working Principle

The working principle of the glass plate level gauge is based on the difference in transparency and refractive index of the liquid. It usually consists of a transparent glass tube filled with a medium, such as water or air. As the liquid level rises into the tube, the difference in refractive index between the liquid and the tube wall causes light to refract, making the liquid level visible. The liquid level height can be determined by observing the relationship between the liquid level position in the glass tube and the scale line.

2. Application

2.1 Chemical industry

Reactor. In chemical reactors, glass plate level gauges can be used to monitor the liquid level of reaction materials to ensure the control and safety of the reaction process.

Storage tank. They are used to monitor the liquid level of storage tanks of various chemical raw materials and products to adjust production plans and raw material supply promptly.

2.2 Petroleum industry

Oil tanks and oil wells. Glass plate level gauges are commonly used in petroleum storage tanks and oil wells to monitor the level of crude oil, natural gas, or other petroleum products to ensure safe and efficient storage and production.

2.3 Pharmaceutical industry

Medicinal liquid preparation. In pharmaceutical production, glass plate liquid level gauges are used to monitor the liquid level during the preparation of medicinal liquids to ensure the quality and consistency of the pharmaceutical output.

Reaction tanks and fermentation tanks are used to monitor the liquid level in reaction tanks and fermentation tanks during the pharmaceutical production process to control the parameters of the reaction and fermentation processes.
