Abstract
The present invention provides an acoustic flow meter assembly (2) for pipes or open channels, said assembly including a frame (24) with a predetermined geometry. The frame has at least one user accessible port (36-42) with the at least one user accessible port (36-42) adapted to receive an interchangeable cartridge (44) which contains at least one acoustic transducer (46) to measure fluid velocity through said frame (24).
Claims20
An acoustic flow meter assembly for pipes or open channels, said assembly including a frame with a predetermined geometry, said frame including at least one user accessible port, said at least one user accessible port adapted to receive an interchangeable cartridge which contains at least one acoustic transducer to measure fluid velocity through said frame.
A tilt lift gate assembly including a gate member which can be raised and lowered from a vertically closed position through to a substantially horizontal disposition, said gate member being pivotally mounted at a top end thereof to a mechanism for pulling said gate member inwardly from the vertically closed position to the substantially horizontal disposition and at least one extension projecting from said gate member with a pivot point at an end of said at least one extension, said pivot point co-operating with a downwardly angled guide means whereby movement of said gate member does not cross said downwardly angled guide means.
An open channel fluid velocity system for measuring fluid velocity of fluid flowing through said system, said system including:
- an open channel containing said flowing fluid;
- an acoustic flow meter assembly including a frame with a predetermined geometry, said frame including at least one user accessible port, said at least one user accessible port adapted to receive an interchangeable cartridge which contains at least one acoustic transducer to measure fluid velocity through said frame;
- and
- a tilt lift gate assembly downstream of said acoustic flow meter assembly, said tilt lift gate assembly including a gate member which can be raised and lowered from a vertically closed position through to a substantially horizontal disposition, said gate member being pivotally mounted at a top end thereof to a mechanism for pulling said gate member inwardly from the vertically closed position to the substantially horizontal disposition and at least one extension projecting from said gate member with a pivot point at an end of said at least one extension, said pivot point co-operating with a downwardly angled guide means whereby movement of said gate member does not cross said downwardly angled guide means, wherein said gate member predictably influences a surface velocity of said flowing fluid.
An open channel fluid velocity system for measuring fluid velocity of fluid flowing through said system, said system including:
- an open channel containing said flowing fluid:
- an acoustic flow meter assembly including a frame with a predetermined geometry, said frame including at least one user accessible port, said at least one user accessible port adapted to receive an interchangeable cartridge which contains at least one acoustic transducer to measure fluid velocity through said frame;
- and
- an undershot gate downstream of said acoustic flow meter assembly, wherein said gate allows a fluid level in front of said gate to back to provide a uniform depth of fluid through said acoustic flow meter assembly.
