Titan Enterprises has announced a new ruggedized IP67 / NEMA 4 compliant version of its OG2 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 uniquely combines high performance with a low cost of ownership.
With a standard flow range from 0.03 to 4.0 litres / minute on 30Cstk oil the new flowmeter is able to routinely achieve outstanding accuracy (0.5%) and repeatability (0.1%).
Beneficially, unlike other flowmeters, measurement accuracy of OG flowmeters improves as the liquid viscosity increases, from a nominal one per cent to around 0.1 per cent of flow rate at higher viscosities.
In the Titan 700 bar 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 very precise 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 highly 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 that the Titan 700 bar OG2 Special flowmeter will have a long product life with reliable, accurate operation throughout.
