Measuring fluid flow under high pressure, such as in hydraulic fluid monitoring, chemical additive injection and other demanding fluid power systems, ensures optimum operational performance and minimises wastage.
Hydraulic systems perform significant work in a broad range of industrial applications, such as:
- Aerospace: in deploying and retracting landing gear on planes, flight control actuators, etc.
- Mining, Construction, Agriculture: in lifting heavy loads with earth-moving equipment or processing materials with rock-crushing machinery.
- Oil and Gas industry: in drilling wells in oil fields or chemical additive injection to improve oil recovery.
- Marine: in pushing and steering the ship through water using propellors and thrusters powered by hydraulic systems.
- Automotive: in Formula One cars incorporating sophisticated hydraulic systems to handle multiple applications, such as power-assisted braking, clutch, gearbox, and throttle actuation.
The oil and gas sector also drives a significant portion of the flow meter market, with conventional flowmeters, such as positive displacement (oval gear) devices, still having the advantage of being proven across a large installed base. These flow meters are crucial for applications like high-pressure additive injection and custody transfer, where accuracy and chemical resistance are vital.
Pressure Testing
Pressure is a key factor in the selection of hydraulic components. Pressure testing each component within a hydraulic system helps to verify its structural integrity and fitness for purpose. The pressure rating of a component indicates its maximum operating pressure.
Pressure testing is carried out during the manufacturing process. It helps to identify defects (such as leaks) early on, preventing potential failures and reducing costly downtime caused by faulty components. It also ensures that the hydraulic system meets safety standards set by regulatory bodies. This ensures compliance. By confirming that both the components and the system as a whole can withstand and function effectively at the required operating pressure, pressure testing plays a vital role in validating the overall performance and reliability of the system.
Onsite Pressure Test Facility
Due to the demand for their high-pressure oval gear flowmeters, Titan made a capital investment into an in-house pressure test rig. This not only enables rapid turnaround of both new and refurbished flowmeters, but from an R&D perspective, allows Titan to pressure test new materials in development.
The Hydratron pressure test rig is capable of testing to a pressure of 1400 bar allowing for testing over the whole range of Titan’s oval gear flowmeters, including the 950 bar high-pressure options. The rig has also proved invaluable when testing new products and simulating the effects of cavitation within a hydraulic system. Alongside a refinement of gear design and standardising the flowmeter designs to improve product interchangeability, Titan’s pressure test rig has proven the design modifications, allowing a potential increase to the maximum operating pressure of its standard oval gear flowmeter range by around 50%.
Key features and benefits:
- High Accuracy and Chemical Resistance
The Oval Gear flow meters improve in measurement accuracy as liquid viscosity increases, from about 1% to around 0.1% of reading at higher viscosities. They are designed to handle a broad range of physical and chemical properties, essential for petrochemical additive injections which vary in viscosity and density. - Robust Construction
Compact and rugged design ensuring long-term performance with minimal maintenance. Models offer pressure ratings from 10 bar to 950 bar and can operate at temperatures up to 150°C. Intrinsically safe options for potentially explosive atmospheres, such as ATEX compliant models, are available.
Reliable Performance
Proprietary oval gear design providing high performance and 0.1% repeatability. Suitable for high-pressure applications such as marine fuel flow measurement, grease supply monitoring in wind turbines, offshore oil drilling additive injection, and biodiesel production. - Custom Solutions
Titan Enterprises collaborates with OEM customers to develop bespoke flow meters that meet specific high-pressure, high viscosity and chemical compatibility requirements, enhancing their application in various industries including oil, petrochemical, and green energy sectors.
By ensuring reliable and accurate flow measurement, Titan’s Oval Gear flow meters contribute significantly to the efficiency and safety of oil and gas processes, from additive injection to fuel measurement; and hydraulic systems in diverse and demanding environments.
