Abstract
A fluidic flowmeter is provided for measuring fluid flow comprising an inlet nozzle, a chamber and splitter located on a centerline with a feedback channel on each side of the chamber with the channel inlet disposed on each side of the apex of the splitter. An outlet channel is disposed on each side of the chamber with the apex of the feedback channel inlet disposed between the outlet channel and the feedback channel. The distance from the mouth of the nozzle to the splitter is greater than the distance between the mouth of the nozzle to the apex between the feedback channel and the outlet channel to provide improved uniformity and sensitivity in measuring fluid flow.
Claims10
A fluid flowmeter comprising a chamber having a centreline (15), an inlet nozzle (22) directed along the centreline for the fluid whose flow is to be measured, a splitter (23) located on the centreline and having an apex (24) facing the nozzle, each side of the chamber on each side of a median plane including the centre line being divided into a feedback channel (28) and an outlet channel (29,14) with an apex (24) therebetween, the feedback channel (28) extending from the apex (24) of the splitter to a location (19) beside the mouth of the nozzle, characterised in that the distance (a) from the mouth of the nozzle (22) to the splitter (23) is greater than the distance (c) from the mouth of the nozzle to the apex (53) between the feedback channel and the outlet channel.
