Abstract

A fluid flow meter having a transparent housing and a piston movable within the housing for indicating the rate of flow of fluid through the housing in accordance with the position of the piston relative to a scale on the housing. Fins are disposed within the housing to receive the fluid entering the housing and to induce the fluid to have a steady and laminar flow and thus present a steady force on the piston for accurate flow readings. A spring urges the piston toward the inlet, and a spring seat is adjustably disposed within the housing so that the spring force on the piston can be readily calibrated and thus the spring will exert the desired force on the piston so that accurate flow readings can be obtained. The entire meter is made of only a minimum number of parts but there is required accuracy and also opportunity to observe the flow through the transparent meter housing.
