Abstract

A wireless multi-range, mass velocity sensor assembly for remote monitoring with direct on-site visual validation of mass velocity is provided. In certain implementations, the sensor assembly comprises a channel body fixture, an obstruction mounted within an aperture formed in the inlet or outlet of the channel body fixture, and an arcuate indicator that protrudes above the fluid flow path and provides clear visual readout of the flow velocity. In some implementations, the sensor assembly can be easily adapted for existing back check valve and other back flow prevention devices.

Claims

1. A fluid flow sensor assembly adapted for measuring in-line fluid velocity, comprising:

an fluid obstruction member, said obstruction member comprising an arcuate appendage extending outwardly from a distal end of the obstruction member;

an indicator lid assembly, said indicator lid assembly having an arcuate configuration and comprises a rim and a receiver pocket adapted for receiving at least a portion of the arcuate appendage; and

wherein said fluid obstruction member is attached to the protruding lid via a rotatable shaft, wherein the fluid obstruction member is pivotable about the shaft, wherein the rim of the protruding lid is adapted to attach to an aperture in a pipe line.

2. The assembly of claim 1 wherein the arcuate appendage is a hollow plastic appendage is pushed up into the receiver pocket

3. The assembly of claim 1, wherein the obstruction member position is sensed electronically

4. The assembly of claim 1, wherein the position of the obstruction position is sensed optically

5. The assembly of claim 1, wherein the flow position is indicated visually against a scale imprinted on the lid portion of the assembly.

6. The assembly of claim 1, wherein the obstruction member movement moves an electronic connection over discrete conductive pads leading to resistors integrated to change resistance of a circuit resulting in a change in current.

7. The assembly of claim 1, wherein indicator has a magnet at distal end and movement is detected by Hall Effect.
