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;
• 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.

Apparatus comprising:

• means for receiving signaling containing information about a fluid flow passing through a pipe that is channelized causing flow variations in the fluid flow;
• and
• means for determining 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.
