Model 2100 Digital Level Sensor

Model 2100 Digital Level Sensor

Categories: Level Sensors

At the core of Electrolab’s Oil & Gas business is the Model 2100 Digital Level Sensor (DLS). Electrolab has over 30,000 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 a stainless steel version (shown at left), as well as a fiberglass version (shown below in the Product Overview).

Using patented 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
  • Condensate
  • Gasoline
  • Salt Water
  • Frac Water
  • Fluids in separation tanks and pressurized vessels
  • Many others

Suitable for production monitoring, inventory control, leak detection (in stagnant tanks) and acceptable for custody transfer measurements, the Model 2100 DLS is also appropriate for H2S environments, high/low alarms and many other applications. Communications to SCADA systems can be digital or analog. The DLS works with many wired and wireless systems using Modbus RTU protocols and ASCII.


After installing the sensor hardware and setting your initial level offset, these sensors require no calibration. All electronics, with the exception of the optional fuse board, are sealed inside the sensor tube, which is constructed of stainless steel (standard) or fiberglass (optional). The apparatus is intrinsicially safe (when used with the Model 2110 Barrier Unit or other suitable Intrinsically Safe Barrier Board), offers low power consumption and is virtually maintenance free.

Oil fields depend on the Model 2100’s quality and reliability. Since their introduction, these level sensors have consistently had warranty repair rates less than 0.25% year after year.
