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 the level, measured through a mechanical device or electrical signal sensor connected to the float. - Pressure Level Gauge: Measures the level by utilizing the relationship between liquid pressure and level. The level height is calculated by measuring the pressure change on a pressure sensor due to the liquid. - Ultrasonic Level Gauge: Measures the level using the propagation time of ultrasound. An ultrasonic transmitter emits waves, and when the beam encounters the liquid surface, part of it is reflected back. The level height is calculated by measuring the reflection time. - Capillary Level Gauge: Utilizes the capillary principle to measure the level. By inserting a thin tube into the liquid, the liquid rises within it, and the level height is calculated based on the rise. - Level Gauge: Measures the level by reflecting waves. The transmitter emits waves, and when the beam hits the liquid surface, part of it is reflected back. The level height is calculated by measuring the reflection time. These level gauges can be selected for application in CO2 tanks based on specific needs and tank design. When selecting and installing level gauges, factors such as liquid properties, working environment, and precision requirements should be considered, ensuring they are compatible with the tank's safe operation and monitoring system.

Before using a CO2 storage tank, certain inspection and filling points must be addressed. Here are some common precautions: - Inspect the tank's exterior: Check for any visible damage, corrosion, or leakage signs. Ensure the tank shell is undamaged. - Check valves and fittings: Verify that the tank's valves and fittings are securely fastened with no leakage. Ensure proper operation. - Inspect the pressure gauge: Check if the tank's pressure gauge is functioning correctly and readings are accurate. Replace or repair if abnormal. - Check the level indicator: Ensure the tank's level indicator is operating correctly and accurately displays the level. Repair or replace if abnormal. - Inspect the pressure relief device: Verify that the tank's pressure relief device (e.g., safety valve) is functioning correctly and set to the required pressure. Repair or replace if abnormal. - Inspect filling equipment: Ensure the filling equipment (e.g., filling pipes, pumps) is operating correctly with no leakage or blockage. Confirm safety and reliability. - Filling operations: During the filling process, pay attention to the following: - Control filling speed to avoid too fast or too slow. - Control filling pressure to prevent exceeding the tank's rated pressure. - Monitor the level to ensure proper filling. - Regularly inspect filling equipment and valves to ensure normal operation. - Safety measures: Adhere to relevant safety regulations and procedures during filling. Operators should wear appropriate protective gear, such as static-dissipative clothing, gloves, etc. - Note that specific inspection and filling points may vary depending on tank type and application. Before using a CO2 storage tank, conduct inspections and operations according to relevant specifications and standards, and consult with experts to ensure safety and effectiveness.

The testing and maintenance of liquid oxygen storage tanks are crucial for ensuring safe operation and extending their service life. Below is a general outline of the testing and maintenance procedures for liquid oxygen storage tanks: - Visual Inspection: Regularly inspect the exterior of the liquid oxygen storage tank for signs of corrosion, wear, and cracks. If any abnormalities are found, promptly repair or replace them. - Internal Cleaning: Regularly clean the interior of the liquid oxygen storage tank to remove accumulated debris and dirt. Use appropriate cleaning agents and tools to avoid damaging the tank. - Level Measurement: Regularly measure the liquid level to ensure it remains within a safe range within the tank. Use a level gauge or other measuring equipment, and record the results. - Pressure Testing: Regularly conduct pressure tests to verify the tank's pressure resistance. Pay attention to controlling pressure and time during testing to ensure safety and accuracy. - Leak Detection: Regularly perform leak detection to ensure the tank's sealing integrity. Use leak detection equipment such as gas detectors or foam leak detection agents. - Valve and Pipe Inspection: Regularly check the valves and pipe connections of the liquid oxygen storage tank to ensure they are sealed properly and there are no leaks. If issues are found, promptly repair or replace them. - Maintenance Records: Keep records of the testing and maintenance activities, including dates, inspection items, and results. These records help track the tank's maintenance history and issue resolution. - Scheduled Maintenance: Develop a regular maintenance plan based on the tank's usage and requirements. Maintenance includes lubrication, bolt tightening, and replacement of seals to ensure normal operation.
