Titan launches ruggedised flowmeter for low flow fluids

Titan Enterprises has announced a new ruggedised flowmeter for metering low flow fluids, such as viscous hydraulic oils used in heavy machinery, at pressures of up to 700 bar and temperatures up to 150°C.

Manufactured in durable 316 stainless steel, the compact Titan 700 bar OG2 Special flowmeter is an IP67 / NEMA 4 compliant version of its OG2 flowmeter.

With a standard flow range from 0.03 to 4.0l per minute on 30Cstk oil the new flowmeter is able to routinely achieve accuracy (0.5%) and repeatability (0.1%).

Beneficially, measurement accuracy of OG flowmeters improves as the liquid viscosity increases, from a nominal one per cent to around 0.1% of flow rate at higher viscosities. In the OG2 Special flowmeter, oval shaped gear-toothed rotors (manufactured in carbon filled PEEK) rotate within a chamber of specified geometry. As these rotors turn, they sweep out and trap a volume of fluid between the outer oval shape of the gears and the inner chamber walls with none of the fluid actually passing through the gear teeth. Ceramic magnets are embedded in the rotors which then actuate a reed switch to provide a pulse output. Each pulse or switch closure then represents a precise increment of liquid volume that passes through the meter. The result is accurate flow measurement almost immune from the effects of varying fluid viscosity, density and temperature.

The combination of durable materials, robust design and proven technology ensures a long product life with reliable, accurate operation throughout.
