ABSTRACT:
A vortex type flowmeter having a body member, a cover member and an interior varying diameter cavity formed in the body member in which fluid is introduced to flow in a generally helical pattern within the cavity, the fluid being introduced at the periphery of the cavity having the largest diameter and the fluid exiting from an aperture at the center of the vortex formed by the helical flow. The flowmeter includes a toothed rotor mounted for rotation within the cavity and the flow of fluid causes the rotor to rotate within the cavity at a rotational rate which is generally directly related to the velocity of flow. The flowmeter is provided with a light-emitting diode and photosensitive transistor combination which senses the passage of each of the teeth as the rotor is rotating within the cavity. This combination is formed as a unitary assembly, a portion of which nests a portion of the rotor. The unitary assembly further includes spoiler means which takes the same general configuration as the rotor, the spoiler means being mounted closely adjacent and parallel to the rotor to cause shear drag on the rotor at high flow rates to improve the down side response time of the rotor after the flow of fluid has been decreased. In this way the linearity of the assembly is enhanced.
