What information can a fixed liquid level gauge provide?

A fixed liquid level gauge is specifically designed to measure the level of liquid within a container. It provides information about how much liquid is present and can often indicate when a container reaches certain fill levels, commonly noted as a percentage of capacity. Choosing an indication of 80% full is particularly relevant, as many gauges are calibrated to provide clear visual or electronic feedback regarding liquid levels at specific thresholds.

The focus of a fixed liquid level gauge is primarily on the liquid level measurement rather than other parameters. For instance, it does not give data about the temperature of the liquid, the type of gas within any container, or the pressures associated with gases. These other attributes require different measuring instruments and methodologies. By selecting 80% full, the gauge's primary function is recognized, aligning with how these devices are employed in practice to ensure safety and proper operation in handling liquids.
