Key Features

The NJEX series odorization systems represent the leading technology in placing Ethyl Mercaptan, a.k.a. odorant, into natural gas flow streams. These systems are engineered to measure and inject precise amounts of liquid odorant into each cubic foot, or meter, of gas that flows down the pipeline.

Our systems are, and always have been, the leading edge in technology. The new NJEX 300 series systems offer technology that allows remote communications, system analysis and reconfiguration in real time via a direct or SCADA comm link. Their odorant measurement resolution is unsurpassed in accuracy to allow you to know exactly how much odorant is placed into the flow stream, not guessing at what's absorbed.

NJEX systems offer a variety of features and options to inject into a range of flow rates from low volume distribution systems to main-line transmission systems. Some of these features and options include:

• Single, double, or multiple injection systems top provide redundancy or high flow capability
• An odorization pump, measurement device, electronic controller and other components specifically designed and built for odorization use.
• Skid mounted tanks and secondary containment skids
• Insulated cabinets with optional heaters
• Remote communications, system analysis, and alarm indication for reliable operation

Sentry4 Software

Our NJEX systems have a brain and they know how to talk. Our WindowsTM based Sentry4 software is specifically written for odorization system management and employs communication, alarm management, remote diagnostic and reporting functions to allow remote management of the NJEX systems in real-time.

Each NJEX system is ready to communicate through the use of ModbusTM protocol, which supports both RTU and ASCII formats. As a standard feature, the NJEX units have two RS-485 commlinks, which are configurable for either redundant SCADA communication or one SCADA and one direct Sentry4 commlink.

The Sentry4 software can utilize one of those commlinks to allow you to remotely monitor system operation from your laptop or PC. This can be especially helpful if Gas Control receives an operation alarm in the middle of night, during the dead of winter. Imagine for a moment a 2:00am alarm call comes in from your odorization system to Gas Control. Instead of suiting up in the middle of the night and driving 50, 100 or more miles you can now walk over to your computer in your robe and slippers, and dial up the NJEX to see what's happening. Once on-line you can analyze the situation, reset parameters if appropriate, start-up a redundant system, and determine if a crew needs to work that overtime for the night. With other systems, you're on the road, with NJEX, you're working smart.

DTEX Odorant Detection System

DTEX incorporates microprocessor technology to ensure the safe use of natural gas. Targeted toward meeting the standards where the scent of odorant must be readily detectable by the human nose, the DTEX blends precise mixtures of air and gas to meet odorant survey test criteria and then records the data.

Capable of conducting two different test methods, the new DTEX Dual Process system can perform either odor concentration or odor intensity to meet the type of test methodology your company impellents for your odorant survey tests.

DTEX is a small handheld instrument that provides the user step-by-step instructions, which typically allow tests to be completed in 2 to 3 minutes. The DTEX microprocessor technology eliminates the need for flow tubes and cross reference charts and allows the on-board storage of 50 test locations and up to 100 tests. Back in the office the test results can be individually reviewed and downloaded into a PC with the Reporter software.

DTEX Reporter Software

With the DTEX System and Reporter Software, you can simply download the test results to your PC, review the data, store it in your database, run analyses, and print the results. Because DTEX can operate as a stand-alone unit or with the Reporter Software Program, you are provided with unmatched flexibility to meet the simplest or most involved odorant level detection program.

The Reporter Software provides the final link between you and total automation in your odorant level detection program. It provides an available list of test sites and users on your PC or notebook to easily upload to your DTEX then go to the field. Basically the Reporter Software eliminates forms to complete and repetitive data entry.
