Titan Enterprises has redesigned its OG3 and OG4 hygienic oval gear flowmeters, introducing precision-machined stainless steel bodies, updated electronics, and dimensional compatibility with established installations.
The revised instruments are intended for liquid measurement and dosing duties across food, beverage, pharmaceutical, cosmetics, and specialist process applications, where repeatability, cleanability, and reliable operation across changing fluid conditions are required.
Oval gear meters measure flow through positive displacement. Liquid entering the chamber turns two precision gears, and each rotation represents a known volume passing through the instrument. The movement is detected electronically and converted into an output for indication, batching, dosing, or integration with a control system.
Because the measurement is based on discrete volumes rather than inferred from fluid velocity, the technology can perform well with viscous liquids and changing flow rates. Compact installation is also possible because the meter is less dependent on long straight pipe runs than several velocity-based technologies.
Machining accuracy remains fundamental to performance, as the clearances between the gears and measuring chamber affect internal leakage, pressure loss, repeatability, and the usable flow range. Titan’s redesigned stainless steel body provides a more robust platform for controlling those dimensions while improving resistance to demanding process and cleaning conditions.
Revised electronics have been introduced without requiring extensive alteration to the surrounding installation. Where a flowmeter forms part of a validated dosing skid, filling machine, blending system, or original equipment manufacturer assembly, changes to dimensions, connections, cabling, or pulse characteristics can create additional mechanical and control work.
Direct interchangeability allows an existing unit to be replaced while retaining more of the pipework, brackets, electrical interfaces, and control logic already in service. Downtime can be reduced, while engineering teams avoid turning a component replacement into a wider modification project.
Validation requirements amplify those gains in regulated production. Altering the measurement chain may require software review, calibration, commissioning, recipe checks, and updated documentation, even when the basic process duty remains unchanged. A replacement that preserves established interfaces can limit the scope of that work.
Repeated cleaning introduces a separate set of engineering demands. Temperature changes can affect seals, electronics, clearances, and fluid viscosity, while cleaning chemicals may attack unsuitable materials. Product residues must also be prevented from collecting in cavities or difficult-to-clean interfaces.
Stainless steel construction supports hygienic operation, although correct installation and material selection remain essential. Seal compatibility, surface condition, drainage, cleaning method, operating temperature, and the characteristics of the measured liquid all influence long-term performance.
As production systems become more closely connected, the flowmeter output increasingly contributes to batch records, quality systems, traceability, material-consumption data, and overall equipment effectiveness calculations. Stable signals and predictable calibration behaviour are therefore as important as mechanical durability.
Measurement drift can accumulate into significant process loss where an ingredient is dosed repeatedly or carries a high unit value. A small error may alter formulation, yield, consistency, and material consumption over thousands of batches, particularly when several metering points contribute to the same product.
Positive-displacement measurement still requires careful application engineering. Suspended solids can obstruct or damage the gears, abrasive media may accelerate wear, and pressure drop must be considered when the liquid is highly viscous or the available system pressure is limited.
Correct sizing is equally important because a meter selected too close to its operating limit can experience unnecessary wear or reduced accuracy. Flow range, viscosity, temperature, pressure, cleaning conditions, and expected service intervals should be considered together rather than treating nominal pipe size as the only selection criterion.
Many process plants are pursuing incremental productivity gains from existing production assets rather than replacing complete lines. Instrument upgrades rarely attract the attention given to major machinery investments, although reliable measurement determines whether recipe control, automation, yield management, and traceability operate as intended.
Brownfield compatibility therefore forms a substantive part of the redesign. Operating factories cannot replace complete skids whenever an instrument family reaches the end of its supported life, and machinery builders need replacement products that can be fitted across an installed base without extensive field modification.
By combining updated construction and electronics with dimensional continuity, the OG3 and OG4 provide a route to modernise selected measuring points while containing downtime and engineering cost. Their long-term performance will rest on stability across production, cleaning, and maintenance cycles, rather than on laboratory accuracy alone.
