Tank gauges must have a scale capable of detecting small changes in what?

Tank gauges are crucial for monitoring various parameters related to the contents of underground storage tanks. The correct understanding of what these gauges need to detect is fundamental for ensuring safety and compliance in operations.

In the context of tank gauges, they must be capable of detecting small changes in pressure to ensure that the tank is functioning correctly and maintaining its integrity. Monitoring pressure is important because it can indicate leaks, overfills, or other malfunctions that could lead to hazardous situations. A sensitive pressure gauge allows operators to respond promptly to any significant changes that could suggest a problem with the tank system.

While temperature, volume, and density are also important parameters in managing underground storage tanks, the specific need to detect small changes in pressure is critical for immediate safety concerns and regulatory compliance. This focus on pressure allows for proactive measures to mitigate risks associated with potential leaks and spills.
