Abstract
We have invented an improved apparatus for electronically measuring fluid flow. The apparatus includes a radiation detection means for indicating the position of a flow indicator in a chamber of a variable area flowmeter and has a reliability, versatility and functional accuracy not obtainable with known variable area flowmeters. The invention may also include a variable area flowmeter with the flow indicator in a tapered fluid flow chamber with a wall and a long axis, the chamber having a front side, a back side, and an operational length substantially parallel to the long axis. The invention has no moving parts and is not intrusive so mechanical malfunction and unwanted leaks can not occur. Useful embodiments include, for example, compact self contained apparatus useful for fitting around existing flowmeters, systems that include flowmeters and systems able to work with some fluids that are visually opaque.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
