ABSTRACT:
An adjustable laminar flowmeter is disclosed for use in fluid flow measurement. The flowmeter comprises a plurality of paths, at least one of which has at least one dimension which is adjustable by means of an adjustment mechanism. A measuring device is located in operative relation with at least one of said paths to measure a characteristic of the flow through that path. By maintaining laminar flow, the ratio of fluid flow through the paths is linear for a wide range of flows. This allows for a simple straight-line approximation of the flow for a wide range of flow. Also, the full scale flow rate through the device is user adjustable. The symmetrical design of the flowmeter enables bi-directional flow measurement.
