MICROCOIVTROLLER BASED LIQUIDVOLUME FLOW RATE METERING SYSTEM

This document presents the project entitled Microcontroller-Based Liquid Volume-Flow-
Rate Metering System. The proposed system is composed of hardware and software
structures. The hardware structure consists of a flow sensor, solenoid valve, and
microcontroller circuitry. Flow sensor senses the liquid flows in the pipeline. The
solenoid valve shall be the final control element to allow appropriate flow to be
controlled in the metering system. The microcontroller circuitry is equipped with LCD
and keypad. LCD displays the flow rate of the liquid flowing in the pipeline meanwhile
keypad allows the user to input data of the volume. The software structure commands the
whole process via the microcontroller input/output ports. In general, the principle of
sensing, measurement, and control is usedin this project.
