What is the purpose of using two gauges during UST installations?

Using two gauges during underground storage tank installations serves the crucial purpose of reducing gauge failure. The dual-gauge system ensures that if one gauge fails or provides inaccurate readings, the other gauge can provide a reliable reference. This redundancy is vital because accurate monitoring of liquids stored in underground tanks is essential for safety, compliance, and environmental protection. If only one gauge were used, and it failed, the risk of undetected leaks or overfills would increase, potentially leading to environmental contamination.

In the context of UST installations, the reliability of monitoring equipment is paramount. By employing two gauges, operators can cross-verify data and catch discrepancies that might arise due to malfunction or calibration issues, thus enhancing operational safety and compliance with regulatory standards.
