Overview

The Electrolab 2100 DLS Series Digital Level Sensors are cost effective, flexible accurate level sensors for tank and level monitoring applications.

2100 series with Modbus RS485 Interface features with low power operation and rapid warmup make it ideal for battery powered Wireless Sensor Operation. RS485 interface allows multiple level and temperature measurement with 4 wires.

The 2100 DLS also has a independent High Level Switch for use in high level shut-in. This allows for a cost effective installation where level measurement and shutdown is required. The 2100 Serial can be equipped with additional float to measure up to 8 independent levels.

 

2100 DLS2011 DLS with High-Level Shut-In Sensor

The 2100 Digital Level Sensor(DLS) with High Level Shut-In delivers consistently accurate measurements of different types of fluids in both hazardous and non-hazardous environments. Multiple fluid densities and temperatures do not affect measurement. The DLS with High Level Shut-In effectively measures the level and temperature of a variety of liquids, including Crude oil, Diesel, Kerosene, Condensate, Gasoline, Water, and Others.

 

RU Flex 2100 DLSRU Flex 2100 Digital Level Sensor

The patent-pending RU Flex 2100 DLS is a flexible, extremely rugged, chemically and abrasion resistant digital level sensor offering continuous, accurate, and reliable monitoring of tank level and temperature. With an 18” flexible radius, one person can install the sensor in 15 minutes. Increased measurement accuracy (3/16″ when ordered with 1/8″ resolution) makes this sensor ready for more stringent API 18.2 measurement requirements.

Wireless Sensor Node Interface

Use with Wireless Modbus Nodes, the 2100 DLS can provide tank monitoring without need to run conduit and cabling on the tanks.
