Carbon dioxide storage tanks offer the following features and benefits: High storage density: These tanks can compress carbon dioxide gas into a liquid state, significantly increasing storage density. Compared to storing it in gas form, liquid carbon dioxide can store more in a smaller tank, saving space and costs. Multiple application fields: Carbon dioxide storage tanks are widely used in various industries, including food and beverage, industrial, fire suppression, and gas supply. Carbon dioxide serves as a preservative, beverage effervescent agent, gas, and fire extinguisher, with extensive applications and market demand. Environmental friendly and renewable: Carbon dioxide is an eco-friendly gas, and its increased concentration in the atmosphere contributes to warming and climate change. By storing and utilizing carbon dioxide, we can reduce its emissions into the atmosphere, achieving environmental protection and sustainable development. Safe and reliable: During design and manufacturing, carbon dioxide storage tanks typically use high-strength materials (such as carbon steel or stainless steel) with excellent pressure resistance and safety. The tanks are usually equipped with safety valves, pressure gauges, level indicators, and other accessories to ensure safe operation. Additionally, carbon dioxide is a non-flammable and non-explosive gas, making it relatively safe. Supply: Carbon dioxide storage tanks provide a stable supply of carbon dioxide. Through tank design and control systems, precise measurement and supply of carbon dioxide can be achieved, meeting the needs of various industries and applications. In summary, carbon dioxide storage tanks have features and benefits such as high storage density, multiple application fields, environmental friendliness, renewable energy, safety, reliability, and supply. This makes them an important storage and supply equipment, widely used in various industries. However, when using carbon dioxide storage tanks, it is still necessary to follow relevant safety operating procedures.

Carbon dioxide tank level gauges are devices used for measuring and monitoring the liquid level of CO2 within the tank. Depending on different working principles and application requirements, common types of CO2 tank level gauges include the following: - Buoy Level Gauge: Uses the buoyancy of a float to indicate liquid level highs and lows, measured through a mechanical linkage or electrical signal sensor connected to the float. - Pressure Level Gauge: Measures level by utilizing the relationship between liquid pressure and level. Liquid pressure changes on a pressure sensor are used to calculate the level height. - Ultrasonic Level Gauge: Measures level using the propagation time of ultrasound. An ultrasonic transmitter emits waves, and when the beam encounters the liquid surface, some of the beam is reflected back. The level height is calculated by measuring the reflection time. - Capillary Level Gauge: Utilizes the capillary principle to measure level. By inserting a thin tube into the liquid, the liquid rises within the tube, and the level height is calculated based on the rise. - Level Gauge: Measures level by reflecting waves. A transmitter emits waves, and when the beam encounters the liquid surface, some of the beam is reflected back. The level height is calculated by measuring the reflection time. These level gauges can be applied to CO2 tanks based on specific needs and tank design. When selecting and installing level gauges, consider factors such as liquid properties, working environment, and precision requirements, ensuring they match the tank's safe operation and monitoring system.
