MODEL 2100 DLS WITH HIGH-LEVEL SHUT-IN

ACCURATE AND VERSATILE


The Model 2100 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.

These digital level sensors are suitable for production monitoring, inventory control, leak detection (in stagnant tanks), high level alarm and well shut-in. Communications to SCADA systems can be digital or analog and the DLS works with many wireless systems using Modbus RTU protocols and ASCII.


ONE DEVICE DOES IT ALL—LEVEL, TEMPERATURE, HIGH LEVEL SHUT-IN


With the addition of a third float, the Model 2100 DLS with High Level Shut-In provides two digital outputs, one for a high level alarm and one for a high-high level shut-in. This is all accomplished with two distinct circuits: one for normal continuous level and temperature measurement—the other for high level alarm and shut-in. The high level alarm requires no power and, unlike competitor’s sensors, is not affected by power outages. The high level alarm and shut-in feature is always active.

An integrated test fixture, allows for testing of the high level shut-in feature at any time and provides the added safety benefit of not having to open the tank hatch. A teflon-coated string attached to the third float provides a means to manually raise the float and trigger the high-level output/alarm.

RU 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 36” flexible diameter, 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 API 18.2 custody transfer level measurement requirements.


The RU Flex 2100 DLS is built on Electrolab’s proven, patented sensing technology. All electronics are enclosed in a proprietary, patent-pending hose with multi-layer barrier properties for difficult environments. This flexible sensor coils into a 36” diameter allowing for one person to install the sensor safely from a catwalk. ALL sensor components fit in one box, which can ship standard carrier to your location. Increased measurement accuracy, 3/16" when ordered with 1/8" resolution, makes this sensor ready for more API 18.2 custody transfer level measurement requirements.


Reliable— No Ongoing Calibration


After installing the sensor hardware and setting the initial level offset, these sensors require no additional calibration. All electronics, with the exception of those in the sensor housing, are sealed inside the sensor tube. The apparatus is intrinsically safe (when used with a qualified intrinsically Safe Barrier, such as Electrolab’s 2110 Barrier Unit) or explosion proof when used with the Explosion Proof Housing (Model 2110EX). The RU Flex 2100 DLS offers low power consumption and is virtually maintenance free.


More Versatile and Reliable than Guided-Wave Radar


Electrolab’s RU Flex 2100 DLS offers greater versatility, flexibility and more robust features than conventional guided-wave radar (GWR) level sensors. A dual float sensor measures multiple fluid levels and temperature measurements through a SINGLE TANK PORT, eliminating the need for multiple sensors in one tank. To accomplish these same measurement and alarm protections, GWR requires two separate ports in a tank. This single device can also read up to eight distinct temperature measurements.

Unlike radar, this sensor is not affected by electro-mechanical interference, tank turbulence or changing environmental variables. Simply install the sensor, set your initial level offset and the RU Flex 2100 DLS is ready to monitor your tank. Under normal operating conditions, no additional calibration is needed—EVER. Ongoing maintence is practically non-existent. The naturally oleophobic non-stick nature of the RU Flex hose helps ensure ongoing measurement accuracy by preventing paraffin and other pollutants from building up on the sensor.Cleaning of the RU Flex 2100 DLS is rarely necessary.


Flexible and Easy to Install


The RU Flex 2100 DLS offers all the benefits of Electrolab’s Model 2100 Digital Level Sensor with the added flexibility of a bendable material that can be coiled to an 35” diameter. This means the sensor can fit neatly in a box for shipping and storage. All components (sensor, housing, cord grip, floats, weight and grounding cable) fit neatly inside the same box, reducing the possibility of misplaced pieces. Once carried to the installation site and assembled, the RU Flex 2100 DLS is easily carried on the shoulder and installed in a tank by one person. A weight, sized based on the length of the sensor and turbulence of the tank, attaches to the bottom of the hose before installation to ensure the sensor straightens out inside the tank and remains straight.

The RU Flex 2100 DLS delivers consistently accurate level and temperature measurements of different types of fluids in both hazardous and non-hazardous environments. With 3/16” accuracy (optional), this sensor is ready to meet API Custody Transfer level measurement requirements. Multiple fluid densities and temperatures do not affect measurement. The RU Flex 2100 DLS is suitable for production monitoring, inventory control, and leak detection in a variety of different types of storage tanks (crude oil, diesel, kerosene, gasoline, water and chemical). Communications to SCADA systems can be digital or analog and the DLS works with most wireless systems using Modbus RTU protocols and ASCII.

Electrolab has over 70,000 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, as well as a fiberglass version.

HIGH LEVEL PROBE


Electrolab’s High Level Probe offers a single-point float switch for either high or low level detection in liquid tanks. The unit mounts vertically through a female NPT port on the top of the tank . The size requirements for this port vary depending on the material used for the probe, fiberglass (left) or stainless steel (right). A side mount version of the High Level Probe is available upon request for stainless steel tubes. An adjustable mounting grip provides for ease of installation. The High Level Probe can be built to custom lengths. The float activates and maintains the output until the level returns to normal.


The UL Certified, Intrinsically Safe, High Level Probe incorporates discrete circuits of magnetic reed switches configured such that when the float is seated on the hose clamp, the switches are activated (closed). As the float rises (approximately 0.75” from the hose clamp), the switch will open indicating a “High” or alarm condition. This configuration is very useful in the event a wire is ever cut, indicating an open circuit.

Typical applications for the High Level Probe include:

  • High Level detection in oil and salt water tanks
  • Control points for pumps
  • Liquid detection in containment areas

SIMPLE, ACCURATE, RELIABLE


This consistently accurate and reliable sensor is not affected by electro-mechanical interference, tank turbulence or other environmental variables. After installation, Electrolab’s High Level Probe is ready to monitor your tank levels.

Ongoing maintenance is practically non-existent—especially, with our patent pending anti-paraffin treatment. This optional, oleo-phobic coating significantly reduces paraffin buildup on steel instrumentation and eliminates the issue of floats sticking and impacting measurement accuracy. Cleaning of the High Level Probe is rarely necessary.
