Tank Monitors

The Sentry tank monitor is a self-contained unit designed and engineered for use on most single or double walled aboveground tanks. The Sentry is primarily used by the automotive and industrial markets to help prevent costly and unnecessary tank overflows or bulk product shortages
of such fluids as oils, waste oils, antifreeze, water and most non-combustible liquids. The Sentry is also ideal for monitoring interstitial space as well. The Sentry is a low cost unit that is simple to install and easily maintained on-site. When activated to an alarm condition, the Sentry will sound its 103-decibel siren for up to 4 days on a fresh 9-volt battery. The Sentry is a simple solution for remote areas where AC power is not accessible.
