What alternative name is used for the fixed maximum liquid level gauge?

The fixed maximum liquid level gauge is also known as the spitter valve. This device is specifically designed to provide a means of indicating the maximum allowable liquid level in a tank. The spitter valve works by allowing liquid to exit (or "spit") from the valve when the liquid level reaches a certain height, thus signaling that the tank is full.

Understanding the function of this device is important in the context of safety and compliance with regulations governing the storage and handling of liquefied petroleum gas (LP Gas). It plays a vital role in preventing overfilling and potential hazards associated with high liquid levels.

In contrast, the other listed options refer to different types of gauges or devices with distinct functions. A pressure gauge typically measures the pressure within a system or tank, an alarm gauge signals an unsafe condition when certain parameters are exceeded, and a flow gauge measures the rate at which a liquid or gas is moving through a system. Each of these devices serves a different purpose and does not fulfill the same role as a spitter valve used for monitoring liquid levels in LP gas tanks.
