Model 2100 Digital Level Sensor
The Model 2100 Digital Level Sensor (DLS) delivers high and consistent accuracy–regardless of the application–with a low per unit life cycle cost.
Utilizing patented reed-switch technology, the Model 2100 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
- Many other fluids
Suitable for production monitoring, inventory control, leak detection 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 and the DLS has wireless capability. Both 16- and 32-bit Modus protocols are supported.
After seating an initial level offset, the sensor does not require any additional calibration. All electronics, with the exception of the fuse board, are sealed inside the sensor tube, which is constructed of stainless steel or fiberglass for special applications. The apparatus is intrinsically safe when connected to the internal barrier board, offers low power consumption and is virtually maintenance-free over its life cycle.
