Flowmeters are designed to give high performance

Designed to be IP 67 / NEMA 4 compliant, Titan OG-1 and OG-2 high pressure flowmeters are available in standard and customer specified configurations. Unlike other flowmeters, the measurement accuracy of oval-gear flowmeters improves as liquid viscosity increases, from a nominal 1% to around 0.1% of flow rate at higher viscosities.

In Titan high pressure OG-1 and OG-2 flowmeters, oval-shaped, gear-toothed rotors 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.
