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 sensor network (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.","PeriodicalId":104356,"journal":{"name":"2006 International Workshop on Computer Architecture for Machine Perception and Sensing","volume":"105 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132228413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, queries are sent out by master node(s) and query-satisfying data are aggregated at optimized points in a sensor network and sent back to master node(s). If patterns of queries sent out by master node(s) are studied, replies can be sent back based on patterns observed. This would be especially beneficial in saving energy for large heterogeneous sensor network whose nodes' location is partially unknown and could change. The contribution of this paper is to propose two simple learning algorithms (block based, incremental learning) to learn about the pattern of queries and also to use an associated sensor and data (ASD). Initial results show promising energy savings with this scheme when compared to flooding.","PeriodicalId":104356,"journal":{"name":"2006 International Workshop on Computer Architecture for Machine Perception and Sensing","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126221993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
