At the core of Electrolab’s business is the Model 2100 Digital Level Sensor (DLS). Electrolab has over 110,000 sensors currently installed in North American production tanks, midstream collection tanks, and many other applications.


Dedication to engineering and development, coupled with relationships with world-class OEMs, integrators and distributors, have placed Electrolab level sensors in mission-critical applications throughout North America—including hazardous locations. Accuracy and reliability are hallmarks of the Model 2100 DLS.


The Model 2100 is available in either a stainless steel version or a fiberglass version  for corrosive/caustic environments (both shown at right). A flexible version, the RU Flex Model 2100, is also available.


A one-piece nylon float designed for especially harsh environments is available as a option. See our Harsh Environment Float page for fluid compatibility information.


Class I, Div 1, Group D Intrinsically Safe with approved barrier device (using standard electronics housing)
Class I, Division 1, Groups A, B, C, D with optional Explosion proof housing (12V or 24V)

API 18.2 Custody Transfer compatible

All stainless steel parts treated with e9 Treatments Pro Performance metal surface treatment to repel paraffin and other contaminants.

No ongoing calibration after initial offset

Measure one or two levels standard (product and interface); three levels with high-level alarm & shut-in option. Measure up to eight temperatures from a single port


Using reed-switch technology, the Model 2100 Digital Level Sensor (DLS) provides accurate measurement of total fluid level, water-interface level and fluid temperature. Up to eight temperature sensors can be placed along the length of the DLS for monitoring different temperature zones. Switch placement ensures accuracy without cumulative error. Up to 32 tanks can be monitored with a single control unit.

The Model 2100 DLS effectively measures levels of fluids with multiple densities:

  • Crude oil

  • Diesel

  • Kerosene

…And many others!
