GUARD Level® Digital Level Indicator (DLI)
Features & Benefits
The DLI gauge is a 100% digital solution for tanks with no top or bottom access (it mounts on the sides). It replaces unreliable glass tube methods.
A single DLI gauge can indicate for an entire tank, and can span up to 20 ft. Marine environment construction with housing made of extruded aluminum with stainless steel caps. It eliminates potential leaks from glass tubes.
The DLI uses a red LED for exact fluid level indication. Ultra-high reliability, low maintenance, and calibrated for life. The DLI gives "at a glance" accurate tank levels.
