Techniques to determine a fluid flow characteristic in a channelizing process flowstream, by bifurcating the flowstream or inducing a standing wave therein

A method comprising:

• receiving in a signal processor or processing module signaling containing information about a fluid flow passing through a pipe that is channelized causing flow variations in the fluid flow by inducing flow perturbations caused by a modulated standing wave across the pipe that sweeps back and forth across a flow cross-section of the pipe and imparts lateral momentum into a combed fluid flow;
• and
• determining with the signal processor or processing module corresponding signaling containing information about a fluid flow characteristic of the fluid flow that depends on the flow variations caused in the fluid flow channelized, based upon the signaling received.

A method comprising:

• receiving in a signal processor or processing module signaling containing information about a fluid flow passing through a pipe that is channelized causing flow variations in the fluid flow by bifurcating the fluid flow through a bridge having two pipe paths/channels fluidically coupled by a balance flow meter as a bifurcated fluid flow;
• and
• determining with the signal processor or processing module corresponding signaling containing information about a fluid flow characteristic of the fluid flow that depends on the flow variations caused in the fluid flow channelized, based upon the signaling received.
