What is a fixed maximum liquid level gauge also referred to as?

A fixed maximum liquid level gauge is commonly referred to as an outage gauge because it indicates the maximum level of liquid in a storage tank, essentially showing how much liquid must be removed or "outaged" from the tank to maintain safety and proper operations. This type of gauge is important in ensuring that the tank does not overflow and helps in managing the inventory of the liquid being stored, particularly for hazardous materials like liquefied petroleum gas (LP gas). The outage gauge type specifically relates to the aspect of monitoring and controlling the maximum fill level, which is critical for safety regulations and operational management in gas storage facilities.

In contrast, a liquid level indicator generally provides a continuous readout of liquid levels without focusing on maximum limits. A standard gauge may refer to various types of gauges used in industry but does not specifically denote the fixed maximum aspect. A pressure gauge measures the pressure within a system and does not provide information about the liquid level directly. Understanding the specific function of a fixed maximum liquid level gauge helps in recognizing its primary role as an outage gauge in the context of storage and safety protocols in LP gas operations.
