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).
Claims13
An arrangement, for controlling and computing a flow rate, comprising:
- a gate through which fluid is flowable at the flow rate;
- a measuring apparatus including acoustic transducers arranged upstream of the gate to
- transmit acoustic beams to traverse the fluid, and
- measure transit times of the acoustic beams;
- the gate having a gate position;
- the gate position being variable to control the flow rate;
- and
- the measuring apparatus being configured to compute the flow rate based on the transit times and on the gate position.
