What is the term used for a gauge that reads higher than the actual boiler pressure?

A gauge that consistently reads higher than the actual boiler pressure is referred to as a fast gauge. This term indicates that the gauge responds too quickly to changes and displays values that can misrepresent the actual conditions within the boiler system. Fast gauges can be problematic because they may lead operators to believe that pressure levels are higher than they truly are, potentially affecting safety protocols and operational decisions.

In the context of boiler operations, having an accurate pressure reading is crucial for maintaining safety and efficiency. Understanding the difference between various types of gauges, such as fast and slow gauges, helps in diagnosing issues and ensuring proper maintenance and operation of boiler systems.
