Flow measurement of hydraulic oil with microsensor clusters

MicroElectroMechanical Systems (MEMS) sensors are widely used in many fields for their exclusive features. It will also be applied in hydraulic flow detection in the future. The feasibility is discussed on microsensors, communication technology and planting strategy in this paper A conceptual design in which a pressure sensor, a temperature sensor, a micro-controller, a communicating unit are integrated on a centimeters squared printed circuit board (PCB) is presented. A group of PCBs lined on the inner wall of hydraulic pipe constitute a flow sensor Compensated by temperature, flow rate can be calculated from the measured pressure gradient. We have gained an optimized distribution strategy method.
