1. Refinery Measurement
Oil refining involves importing crude oil of varying degrees of purity and separating it (by distillation) into various compounds. These may include gasoline, naphtha, asphalt, diesel fuel, jet fuel, and many others. Bell Technologies manufactures products for most every step in the refinement process.
As crude oil is unloaded from a ship or rail car and sent into temporary storage, its volume must be measured accurately. Subsequently, each step in the refinement process necessitates either accurate flow or density measurement. Delivery of final product to the end user is known as “custody transfer”.
Flow measurement of refined products ideally involves the use of an extremely durable and accurate primary element such as the TORUSWEDGE. Its unique circumferential inlet and outlet ramps help it achieve excellent rangeability and lifespan in even the harshest conditions. The device can be made of almost any material -- stainless, carbon steel, PVC, or whatever your process requires.
Accurate density measurement is also necessary in numerous refined products applications. Knowledge of product purity is one key step in the refinement process. Bell Technologies’ VTDensitometer provides clients with a line size, line pressure device for analyzing end products like kerosene, various fuel blends, and naphtha.
2. Chemical Plant Measurement
Bell Technologies' flow and density meters are helping chemical processes ensure accurate reaction, optimize production, increase safety, and save thousands every year.
With our products you can measure mass flow, volume flow, density, and temperature with a single device. There are no moving parts which results in no maintenance or repair. You can install the TORUSWEDGE anywhere with no flow conditioning or straight pipe run required. Our accuracy over a wide flow range from a single meter optimizes plant efficiency and our repeatable, direct mass flow measurement eliminates problems involved in volume measurement.
The TORUSWEDGE and VTDensitometer are used in a range of applications:
Check metering of natural / industrial gases
Greenhouse Gas compliance
Safety Certified Products (SIS)
Batch, continuous reactor and high turndown feed
Net flow/catalyst and concentration measurement
Measurement of high corrosive acids, bases and liquid-solid slurries
Custody transfer for rail car and truck loading/unloading
Combustion control of burners and boilers
High speed filling, dosing and batching
Measurement of consumer product ingredients
3. Tanker Offloading
The traditional quantity measurement via tank gauging, for example, can be associated with a great amount of uncertainty due to:
Error prone volume to mass calculation
Air content caused by tank stripping and the “cappuccino effect”
Very often, this leads to incorrect billing and unwanted bunker disputes between supplier and buyer.
For these reasons, ship owners and barge operators have been increasingly installing special bunker fuel metering systems that ensure transparent and highly accurate bunkering. The TORSWEDGE flowmeter, which have been tried and tested in custody transfer applications, and the VTDensitometer are ideal for handling these measurement issues.
Use of this product gives you:
A high level of transparency during bunkering due to continuous and simultaneous monitoring of process parameters, such as:
– Mass flow (bidirectional)
– Bunker fuel quantity
– Density, pressure and temperature
– Air index
Fewer bunker disputes, i.e. discrepancies between billed and delivered bunker fuel quantity
Clear documentation of irregularities due to an excessive tank stripping or the “cappuccino effect”
4. Flare Metering
Flaring is the burning of natural gas waste associated with oil production. According to World Bank, estimation of more than 150 billion cubic meters of gas (approximately the annual gas consumption of Germany and France combined) is flared or vented into the atmosphere every year. This adds to the greenhouse gas emissions associated with global warming and has triggered allegations of serious health consequences to people and animals.
One of the challenges in reducing flaring has been finding an accurate way to measure the amount of gas being flared. However, this highly technical problem can now be effectively addressed using uniquely simple measurement technology called the TORUSWEDGE flow meter.
Accurately measuring with a flare gas flow meter, helps oil companies comply with industry regulations on emissions, conserve energy and measure how much gas they are venting. The TORUSWEDGE flow meter is not only easy to install and cost-effective, but its high turndown ratio allows oil companies to measure a wide range of flow rates.
Downstream Oil & Gas
The downstream oil & gas industry commonly refers to the refining of petroleum crude oil and the processing and purifying of raw natural gas as well as the marketing and distribution of products derived from crude oil and natural gas.
In this sector, it is more important than ever to invest in automation improvements that help you increase asset utilization and productivity, minimize product loss, and decrease the number of environmental and safety risks. That’s why our industry experts work with your project and operations teams to reduce measurement uncertainty, optimize plant performance, and identify opportunities to improve competiveness.
With our TORUSWEDGE and other flow measurement devices, our automation solutions equate directly to increased profitability.

5. Cavern Storage
Natural gas liquids (NGL) including ethane, propane, butane, isobutene and pentane are important and widely used fuels and feedstock for petrochemical plants. NGL are most commonly held in inventory underground under pressure in three types of facilities: depleted oil and/or gas reservoirs; aquifers; and salt cavern formations. In salt cavern storage, NGL is transported into and out of the storage cavern by injecting or withdrawing brine. The brine is stored in ponds to ensure availability of brine for product transfer.
The industry challenge for cavern storage comes when brine is moved into and out of the cavern. Here, safety devices are required to detect hydrocarbon leaking into the brine. Hydrocarbons leaking into the brine circuit pose an environmental threat and an explosion or ignition hazard. In some cases, government regulations drive the type and the number of hydrocarbon breach detection devices needed on each cavern. For example, the Texas Railroad Commission Rule 95 states that each NGL storage cavern must have two forms of detection. In addition, measurement of the volumetric flow into and out of the cavern is an important process control measurement.
Traditional Flow Meter Challenges
Due to the corrosive nature of brine, traditional inline meters require frequent and costly replacement and create potential leak paths.
Tradtional flow meter accuracy is also challenged by the presence of gas in the brine.
Measuring the flow rate of liquids and salt when solution mining to create the storage dome.
6. Line Integrity
Many oil and gas assets around the world are operating beyond their nominal design life. The challenges to maintain production capability in a cost effective way while preserving the integrity of those assets is becoming a major concern. Implementing integrity management requires that all aspects of operations essential to safety and integrity are properly designed, constructed, tested, operated, inspected and maintained in a sustainable holistic and systematic way. But, maintenance costs can be extravagant.
There is a more simplistic, cost-saving way to maintain flow lines, however. Measurement of the flow amounts registered between two TORUSWEDGE meters can point out product loss and issues with the integrity of the line.
