How a glass plate level gauge works.
Glass plate liquid level gauge is a common liquid level gauge. Its design principle is simpler than other liquid level gauges, and the measured liquid level value is relatively low. However, the glass plate liquid level gauge also has the characteristics of simple structure and convenient use. Measurements are not high in some environments.
The glass plate level gauge directly reads the liquid level through the transparent glass casing. The glass plate level gauge mainly indicates the liquid level height in the closed container. The internal materials of the glass plate level gauge are mainly steel, steel paper and graphite. Therefore, glass level gauges cannot be used to measure the corrosion of these materials.
Due to the simple design and structure of the glass plate liquid level gauge, the use is very convenient, the liquid level data can be obtained intuitively, and the readings are clear and reliable. The glass plate level gauge has simple maintenance, low maintenance cost, long service life and durability, and is an indispensable level gauge in industrial production.
The glass plate liquid level gauge is designed with an upper and lower valve structure, and the valve is equipped with a threaded joint, which is connected with the container of the measured medium through a flange to form a connector. Under the action of the connector principle, the glass plate liquid level gauge indicates that the liquid level is consistent with the liquid level in the container, and the liquid level in the container is obtained by reading the liquid level height data in the external glass. In order to reduce the possibility of leakage, the glass plate level gauge is also equipped with steel balls on the upper and lower valve parts. When the glass cover of the glass plate level gauge is broken, the steel ball will block the flow channel in the level gauge under the pressure in the container, forming the sealing effect of the container and avoiding the leakage of the medium in the container.
The glass plate level gauge can be directly used to investigate the liquid level of the medium in various containers. It is suitable for liquid level indication in petroleum, chemical and other industrial fields. The liquid level gauge has a simple structure, intuitive and clear investigation, no blockage, no leakage, convenient installation and simple maintenance. The upper and lower ends of the glass plate level gauge are connected to the container to form a communication device, and the actual height of the liquid level in the container can be directly measured through the glass plate. The upper and lower valves are equipped with safety steel balls. When the glass is accidentally damaged, the steel balls are actively sealed under the action of the internal pressure of the container to prevent the liquid from overflowing in the container and ensure the safety of operators.
The level meter mainly measures the liquid level of a certain medium or the interface of two liquids with different specific gravity and the material level of solid materials in towers, tanks, and tanks. The most common liquid level gauges are glass tube level gauges, glass plate level gauges, and others include differential pressure level gauges and buoyancy level gauges (such as float level gauges, level switches, and float level gauges). gauges, float level gauges, steel belt level gauges, tank level weighing instruments, etc.). For the level detection of solid materials, there are resistive level meters, capacitive level meters, level switches, weight detection level meters, tuning fork level meters, ultrasonic level meters, radioactive level meters, etc.
(3) Liquid level gauge The liquid level gauge is an instrument that displays the liquid level in the steam drum. There are on-site liquid level gauges and liquid level gauges that are transmitted to the control room through transmitters. Among them, the liquid level gauge installed on site is designed according to the principle of equal height of the liquid column in the communication device. It is usually a glass tube or hollow glass plate for observing the liquid level; the remote liquid level gauge is used to convert the liquid level into pressure The signal is transmitted through the transmitter, and the principle is similar to that of the remote pressure gauge. The operator observes and adjusts the liquid level of the steam drum through the liquid level gauge to prevent the occurrence of water shortage or full water accident of the boiler.
