Abstract
An aspect ratio flow metering device may comprise a concentrate inlet portion, one or more restricted flow portions of tubing fluidly connected to the concentrate inlet portion, and a metered concentrate outlet portion fluidly connected to the one or more restricted flow portion of tubing. The narrowest part of the one or more restricted flow portions of tubing may each have a length (RL): inner diameter (RID) ratio of at least 10:1. The metered concentrate outlet portion may have an inner diameter (OID) greater than RID. The concentrate inlet portion may have an inner diameter (IID) greater than RID. The aspect ratio flow metering device may be structurally configured to limit flow of a concentrate into a hydrodynamic mixing apparatus. Also disclosed are methods for using the aspect ratio flow metering device to mix fluids.
