Abstract
The disclosed flow sensors involve rotor-bearing probes proportioned for entry through a hole in a pipe. By omitting flow-straightening vanes, the rotors can be relatively large. Multiple rotors distributed across the flow passage, especially one or more pairs of oppositely rotating rotors, have respective rotation sensors whose outputs are combined for averaging out the varied effects of the flow on the rotors. The rotation sensors produce trains of pulses that are converted to narrow spikes before being combined.
