Bayoumi, “Remote Measuring of Flow Meters for Petroleum Engineering and Other Industrial Applications,” The 2006 IEEE International Workshop on Computer Architecture for Machine Perception and Sensing (CAMPS06), September 18-20, 2006, Montreal, Canada.Abstract: Reliable remote measuring of flow meters for the petroleum gas industry is proposed in this work. The monitoring of flow rates and the total amount of the fluid flow is collected using a manual process. The main goal of this work is to implement a mechanism that avoids human error and achieves reliable, continuous, and accurate monitoring. We employed the NuFlo Measurement System Model MC-II Flow Analyzer to prototype our monitoring mechanism for measuring the liquid flow and a Crossbow Technology MICA2 mote and MDA300CA Data Acquisition Board to transmit collected data via a Wireless SensorNetwork (WSN). The flow analyzer generates a pulse signal whose frequency depends on the flow rate. The mote is used to count the number of pulses and send it to the host computer. An amplifier lets the mote detect the voltage level differences and overcome signal weakness. The host computer stores the data received from the mote into a PostgreSQL database for use in preparing Excel sheets and graphical displays in real time. The flow rate and the total flow amount collected by the host computer match those shown on analyzer. The design and implementation of our prototype serves as a proof of concept of how existing analog sensors used to monitor the flow rate and volume of the oil and water in petroleum production can be integrated with other devices in a WSN.
