True or False: A gage glass can be replaced by 2 remote level indicators at operating level.

A gage glass can indeed be replaced by two remote level indicators at the operating level, making the statement true. The primary purpose of a gage glass is to provide a visual indication of the water level within a boiler or other vessel. However, when two remote level indicators are installed correctly and are continuously monitored, they can serve as reliable substitutes for a gage glass.

Using two indicators adds a layer of redundancy, ensuring that if one indicator fails, the other can still provide accurate information about the water level. This is particularly important for maintaining safe operating conditions and avoiding potential hazards associated with incorrect water levels.

In contrast, relying solely on one remote indicator may not offer the same level of reliability. Thus, using two remote level indicators meets the safety and operational requirements that the gage glass system provides.
