HYDRAULICS 16 HYDRAULICS & PNEUMATICS March 2026 www.hpmag.co.uk Accurate flow measurement plays a critical role in the performance and reliability of high-pressure fluid systems. Whether in hydraulic power units, lubrication circuits or oilfield chemical injection skids, maintaining precise control of fluid flow is essential for safe and efficient operation. In these environments, inaccurate measurement can affect system efficiency, increase operating costs and, in some cases, introduce safety risks. Flow measurement becomes particularly challenging when systems operate at very high pressures or with fluids that vary in viscosity or contain chemically aggressive components. Under these conditions, meter technologies that perform well in standard industrial applications may struggle to maintain stable, repeatable readings. Titan Enterprises has developed its high-pressure Oval Gear flow meters specifically for these demanding environments. The meters are designed to provide consistent measurement across a range of challenging operating conditions, including high pressures, fluctuating viscosities and chemically aggressive fluids. In hydraulic and fluid power systems, operating pressures can magnify the effects of even minor inefficiencies. Applications such as additive injection, lubrication monitoring and hydraulic actuation all rely on accurate flow measurement to ensure that fluids are delivered at the correct rate. If flow measurement is inaccurate, the consequences can include overdosing of additives, excessive lubricant consumption, premature component wear or reduced energy efficiency. In critical systems this may ultimately lead to unplanned downtime. For these reasons, positive displacement flowmeter technologies continue to be widely used in highpressure applications. Oval gear flowmeters in particular measure fluid volume directly as it passes through the meter, providing a measurement that is largely independent of flow profile or turbulence within the pipework. This measurement principle makes the technology well suited to applications where repeatability and accuracy are essential. Industries that commonly use high-pressure hydraulic systems include aerospace, offshore energy, marine propulsion, heavy equipment and highperformance automotive engineering. In oil and gas operations, flowmeters must often operate continuously while handling high-viscosity fluids or aggressive chemicals under elevated pressures. For components used in high-pressure systems, the stated pressure rating must be supported by robust testing. Pressure testing verifies the structural integrity of the component and ensures that it can operate safely throughout its service life. Titan Enterprises carries out pressure testing at its dedicated in-house test facility as part of the development and production process for its oval gear flow meters. Testing under controlled conditions allows engineers to assess component strength, validate mechanical integrity and confirm compliance with applicable safety standards before products are deployed in the field. At the centre of Titan’s testing capability is a Hydratron pressure test rig capable of testing flowmeters at pressures up to 1,400 bar. This exceeds the maximum operating pressure of the company’s current product range and allows both production testing and development work to be undertaken under extreme conditions. Using this facility, Titan can test and qualify flowmeters rated for pressures up to 950 bar. It also allows development engineers to evaluate how designs perform beyond their nominal limits during the product development phase. This testing capability has supported improvements in several areas of meter design, including gear geometry, materials selection and platform standardisation. According to Titan, these developments have strengthened product robustness and increased component interchangeability across the flowmeter range. The work has also created the potential to increase the maximum operating pressure of standard oval gear flowmeters by approximately 50%. The test facility also supports advanced research and development work, including cavitation simulation and the evaluation of new materials for future high-pressure applications. Titan’s oval gear flowmeters are often selected for applications involving viscous Putting the pressure on flow measurement in high-pressure systems fluids because their measurement performance tends to improve as viscosity increases. The company reports that its meters can achieve measurement performance ranging from approximately ±1 percent down to ±0.1 percent of reading depending on operating conditions. This characteristic makes the technology particularly suitable for applications such as additive injection and lubrication systems, where fluids may fall outside the optimal operating range of other flow measurement technologies. Titan’s oval gear flowmeters are available with pressure ratings from 10 bar up to 950 bar and operating temperatures up to 150 °C. ATEXapproved intrinsically safe versions are also available for use in hazardous environments. In addition to supplying standard flowmeters, Titan works with OEM manufacturers to develop applicationspecific measurement solutions. Customised designs can address particular requirements relating to pressure, viscosity or chemical compatibility. These collaborative projects allow flow measurement systems to be integrated into complex equipment used across sectors such as oil and gas, petrochemical processing, marine engineering and emerging energy technologies. By combining positive displacement measurement technology with highpressure testing and in-house product development, Titan Enterprises aims to provide flow measurement solutions capable of operating reliably in demanding fluid power environments.
