Abstract
A pulser driver assembly of a measurement-while-drilling tool that includes an improved flow switch is disclosed. The flow switch uses multiple accelerometers of different types that measure acceleration changes in a system. The accelerometer data is then filtered and processed by an onboard microcontroller. The filtered data is then passed to a fuzzy logic voting algorithm which systematically and robustly characterizes the signal, and identifies the flow state.
