How can overfilling of LPG tanks be prevented?

Using liquid level gauges and overfill protection devices is an effective method to prevent the overfilling of LPG tanks. Liquid level gauges provide real-time data on the amount of liquid in the tank, helping operators monitor levels accurately. Overfill protection devices are designed to automatically stop filling when the tank reaches a predefined level, ensuring that it does not exceed safe limits. These devices serve as crucial safety features that help mitigate the risk of leaks and accidents due to overfilling.

In contrast, limiting tank size may not always be a viable solution since it doesn't directly address the need for accurate monitoring or filling control. Manual checking, while better than no monitoring, is prone to human error and may not provide the necessary precision needed in many operational contexts. Regularly emptying tanks can be operationally burdensome and does not contribute to preventing overfilling during normal usage scenarios. Hence, relying on advanced monitoring and protection systems is the most effective and safety-conscious approach to manage LPG tank filling.
