Abstract: In industries there will be many big pipelines carrying various types of liquids, including the flammable liquids and corrosive liquids. It is necessary to control the flow rate of the liquid for enhancing the processes and to prevent the accidents. The paper proposes a methodology to monitor and control the liquid flow in the pipeline of industries through web server. There are many systems to do the same, but this is about to monitor and control the flow of liquid using Internet with the help of Raspberry pi and Arduino. The flow rate of the liquid is measured by Hall Effect sensor based flow meter. Arduino, a microcontroller development board reads the pulses from the flow meter and sends it to Raspberry pi, a microcomputer to control the electro valve which is connected to the pipeline. Server was setup by means of Raspberry pi.

Keywords: Arduino, Raspberry pi, Flow meter, Hall Effect sensor, electro valve.
