Oil Flow Measurement

Bell Technologies offers a complete differential pressure solution for measuring homogeneous and non-homogeneous flows whether they are high or low pressure applications.

The compact design and lack of sharp edges allows operators to continuously monitor mud flow both in and out of the well with consistent readings and no down time.  The newest patented design integrates easily into existing infrastructures and provides a solution for drilling mud, multiphase flow, high viscosity slurries, drilling fluids, corrosive liquids, produced water, gas, and large flow ranges.


The TORUS can handle pressures up to 20,000 psig and flow rates up to 100 barrels per minute, thus, ensuring long-term asset reliability and safe rig operations.

Drilling Fluids -- Recent flow tests conducted on several types of drilling mud show that, unlike other meters, the TORUS volume flow output remains stable through all phases of fluids – including transitional periods when air, liquid and particulates (multiphase flow) were present.

Sampling -- Newer standards and processes in industry require more and more testing in order to meet requirements, Taking a sample of your process through the core of the differential pressure device is made simple with the new CENTER-TAP TORUS. To learn more, click here.

Multiphase Flow -- In a competitive multi-flow test against the Coriolis meter, the TORUS performed reliably and consistently. NOTE: Accuracy of the CENTER-TAP TORUS is predicated by the accuracy of the measured density. To learn more, click here.


Slurries --  Flow measurement of slurries has always been one of the most challenging applications in flow metering.  Since the Bell Technologies' TORUS gives a consistent reading no matter what is flowing through the pipe, it minimizes these difficulties and lowers your cost of ownership..

Liquids --  Whether your application is straight-forward or challenged by limited installation space, disturbed flow, high turn downs, wet gas, or dirty or abrasive fluids, the Bell Technologies' TORUS can manage your volumetric flow. To learn more, click here.

Gases -- The TORUS can be used to measure dry or wet gases no matter what the gas contains or what its pressure rating might be. One of the first TORUS gas meters is still in operation at the Moscow, Russia, city after more than nine years. NO replacements meter have ever been needed. To learn more, click here.


Steam -- The TORUS is an advanced differential pressure instrument ideal for use with liquid media in rugged conditions where accuracy, low maintenance and cost are important. It is especially useful in tight-fit and retrofit applications. To learn more, click here.

Produced Water -- Water coming up from a production well brings many flow measurement issues. Rocks, sediment, flow back, and a variety of other issues can often cause a device to falter. However, with the Bell Technologies' TORUS these issues are a thing of the past. To learn more, click here.
