What is a fixed liquid level gauge that indicates the maximum filling limit of a container called?

A fixed liquid level gauge that indicates the maximum filling limit of a container is called a fixed maximum liquid level gauge. This device is essential for safely filling storage tanks, as it provides a clear indication of when the maximum allowable liquid level has been reached. Such a gauge helps prevent overfilling, which can lead to spills, leaks, or other hazardous situations.

By utilizing this type of gauge, operators can ensure compliance with safety regulations and maintain the integrity of the container's contents. The fixed nature of the gauge means that its measuring point is established and does not change, providing reliable and consistent readings regarding the liquid level in the container. This is particularly important for the safe handling and storage of materials like propane, where controlling the liquid level is critical to prevent accidents.
