What does a tank interstitial sensor monitor?

A tank interstitial sensor is designed to monitor the space between the inner and outer walls of a double-walled storage tank. This interstitial space is crucial for leak detection; by monitoring for the presence of liquid in this area, the sensor can alert technicians to potential leaks from the inner tank that could affect the environment or compromise safety.

The interstitial monitoring system typically functions by detecting changes in fluid levels or the presence of a liquid, which can indicate a breach in the tank containment. This is a critical part of maintaining compliance with environmental regulations and ensuring the safety of fuel storage operations.

The other options involve parameters related to the contents of the tank or the tank's environment. Monitoring fuel levels, temperature, or chemical composition are functions of different types of sensors but are not the focus of interstitial sensors. Their primary role is specifically related to leak detection within the containment systems of the tanks.
