摘要： An apparatus, system and methodology enable non-intrusive measurement of parameters related to fluid flow in a conduit. An acoustic sensor is located along the conduit and includes a mechanical amplifier having an acoustic input coupled to the conduit and a microphone coupled to the mechanical amplifier. The microphone receives mechanically amplified acoustic energy from the conduit and establishing first signals which are processed for generating second signals which are related to fluid flow in the conduit. The second signals can include quantitative flow data and qualitative data such as change in state and alarms. The second signals can be transmitted wirelessly to a remote site for further processing. Use of low power components and power management enable long term operations on battery power.
