ABOUT THIS PRODUCT

Electrolab 2100 Series Flex Level Sensor is a patent-pending flexible, rugged, chemically and abrasion resistant digital level sensor for reliable tank monitoring. A bend radius of 36″ makes the RU Flex Sensor a one-man installation job. Electrolab RU Flex Level Sensors are able to measure fluid levels and temperature measurements through a single tank port. The user is able to measure one or two levels with an additional third level with high-level alarm and shut-in option. The high-level alarm shut-in requires no power and, unlike competitors’ sensors, is not affected by power outages. Available in three measurement increments and lengths between 2 and 48 feet.
