Control of Explosion-Proof Facilities

Control of Explosion-Proof Facilities

Facilities that handle flammable liquids and fuel require high safety and reliability standards for equipment. In such conditions, it is especially important to consider risks related to potential ignition or explosions, necessitating the use of certified solutions that comply with explosion-proof standards. International ATEX (Atmosphère Explosible) certification is a mandatory requirement for equipment operating in high-explosion-risk zones.

According to ATEX classification, hazardous zones are categorized based on risk levels:

Zone 0
A zone where an explosive atmosphere is constantly or frequently present (e.g., near flammable liquid storage tanks)
Zone 1
A zone where an explosive atmosphere may occur under normal operating conditions but for a limited time (e.g., near regularly used refueling sites)
Zone 2
A zone where an explosive atmosphere may occur only in the event of an emergency and for a very short period

For effective and safe control and management of fuel processes in such facilities, equipment must be certified for safe operation in these zones. This equipment must eliminate all potential ignition risks, such as sparks, high temperatures, or static electricity.

Solution Components

Omnicomm offers solutions that are ideally suited for explosion-proof facilities, including equipment certified to international standards.

Omnicomm LLS-Ex 5 Fuel Level Sensor

An explosion-proof digital sensor designed for measuring fuel levels in vehicle tanks and stationary fuel storage facilities operating in hazardous zones. It ensures high measurement accuracy and meets international fuel measurement standards for such zones.

Omnicomm BIS-MX Spark Protection Unit

A device designed to ensure spark safety when using fuel level sensors in explosion-risk zones. The BIS-MX protects equipment from spark discharges, preventing ignition in explosive atmospheres. It allows simultaneous connection of two sensors to a single GPS-tracker.

Omnicomm RKTZ-MX Splitter

A device that enables the connection of more than two Omnicomm LLS-Ex 5 fuel level sensors to a GPS-tracker while maintaining explosion-proof safety requirements.

To ensure safety and reliability at explosion-proof facilities, it is crucial to use certified equipment that meets international standards like ATEX. Omnicomm products, certified for operation in these environments, not only enhance safety but also improve fuel accounting accuracy, helping prevent losses due to fraud or mismanagement.

Using high-quality certified equipment that meets all safety requirements minimizes explosion and fire risks, ensuring uninterrupted operations and worker safety. Implementing Omnicomm solutions at such facilities enhances both safety and fuel resource management efficiency.

Frequently asked questions

Do I need an explosion-proof fuel sensor?

You need an explosion-proof sensor like LLS-Ex 5 if you are monitoring fuel tankers, oil depots, gas stations, chemical plants, mining operations, or any ATEX-zoned hazardous environment. LLS-Ex 5 is ATEX-certified, offers 5,000V galvanic isolation via the BIS-MX spark protection unit, and comes in lengths up to 6 meters, the longest in the OMNICOMM portfolio.

ATEX zone classification splits hazardous areas into three categories based on how often explosive atmospheres are present. Zone 0 is continuous (inside a fuel tank itself), Zone 1 is occasional (around tank vents, fuel transfer points), and Zone 2 is rare (general site areas where a leak might occur). Equipment installed in any of these zones must carry matching certification, and using a non-rated sensor is a safety and insurance violation, not just a regulatory one. LLS-Ex 5 is rated for Zones 0, 1, and 2, and must be connected through the BIS-MX spark protection unit, which provides the 5,000V galvanic isolation that limits energy in the sensor circuit to non-ignition levels. LLS-Ex 5 is available in 1500, 2000, 2500, 3000, 4000, 5000, and 6000 mm lengths for global markets, covering everything from medium tankers to large depot storage. The sensor itself carries a lifetime warranty, and the BIS-MX carries 3 years.

What certifications and quality standards does OMNICOMM hold?

OMNICOMM products are certified to ISO 9001:2015 (quality management), ATEX (explosive atmospheres), E-Mark (European vehicle components), FCC (US electromagnetic compatibility), CE (European conformity), and EAC. The company holds 30+ patents including the OMNICOMM LLS protocol, which became an industry standard. In 2020, Frost & Sullivan awarded OMNICOMM the Growth, Innovation & Leadership Award in connected truck telematics.

Each certification matters for a specific market and use case. ISO 9001:2015 covers the quality management system across design, manufacturing, and support, and is the baseline for any large corporate or government procurement. ATEX (specifically for LLS-Ex 5 sensors with BIS-MX) is required for any installation in hazardous areas such as fuel tankers, depots, gas stations, refineries, mining sites, and chemical plants. Operating without ATEX certification in these zones violates insurance terms and creates personal liability for site managers. E-Mark is the European vehicle component type-approval, required for any sensor or tracker installed on a road-going vehicle in the EU. FCC is the US equivalent for electromagnetic compatibility. CE is the European conformity mark covering safety, health, and environmental requirements. EAC is the Eurasian Economic Union equivalent. The Frost & Sullivan 2020 Growth, Innovation & Leadership Award recognized OMNICOMM for the combination of high-end fuel sensors, hardware terminals, and a highly scalable cloud platform, citing the company as a pioneer driving innovation in connected truck telematics.

Can a fuel monitoring system track stationary fuel tanks, generators, and depots?

Yes. OMNICOMM equips far more than vehicles. Stationary applications include gas stations, fuel depots, generator tanks for telecom towers and data centers, pumping stations, boilers, and tank farms. ATEX-certified LLS-Ex 5 sensors paired with the BIS-MX spark protection unit cover hazardous zones up to 6 meters deep. ICON Display and LLD Indicator give on-site readouts for operators.

Telecom operators in emerging markets manage thousands of tower sites powered by diesel generators, and fuel theft from those generators is a major cost line; OMNICOMM sensors on the generator day-tank or main reservoir give the operator real-time levels and theft alerts. Data centers run backup diesel generators that must have guaranteed fuel availability; precision sensors prevent the silent drift toward empty that paper-based monitoring cannot catch. Gas stations and depots use LLS-Ex 5 sensors in the ATEX-rated underground tanks to track inventory, reconcile deliveries against actual received volume, and detect leaks. For agricultural and construction operations, the on-site fuel tanker that distributes fuel to equipment is itself monitored to ensure that what the depot reports dispensing matches what the receiving equipment reports getting. Silver Spark Apparel in India deployed OMNICOMM sensors on factory generators specifically to prevent production-line downtime, with avoided losses calculated at around $30,000 per hour of prevented downtime.
