INTERFACE REGION LEVEL MEASUREMENT

This progress report is intended for final year project under Electrical & Electronic Engineering Department which provide the introduction that consist of background study, problem statement, objectives of this project and theory are also stated within the introduction part. In order to ensure correct operation of the plant or equipment involved, it require careful control of liquid level in many processes involving the storage, movement or processing of liquids. In order to maintain a smooth operation and to provide a quality product to consumer, it‟s a vital for an operator to emphasize a mutual measurement to identifying the interface level between two media with different specific of gravity either liquid or solid in the same tank or vessel, such as oil and water or water and sand.
These methods are also extensively being used in chemical industries and petrochemical plant. This paper aims to tackle the weaknesses of the current system in terms of costly and complex equipment‟s, high maintenance cost, instability and inability to control and monitor from remote location. It describes how the innovative interface level control system can be characterized as an event-based system, where every control actions are primarily deliberated compared to the events formed by instabilities from surrounding elements.
This project report offers a costs-saving solution with low maintenance required, as well as producing a great performance results. This system eliminates the over-dependability of the industry on human workforce. The system will continuously measure, control and monitor two of the most important parameters, interface liquid level and total level, as the quality and ability of process are highly affected by these factors.
Through refer the separating funnel method, a mixture of liquid will be shaken and then left it until becomes steady again. Liquid with heavier density around 1 or above such as water will goes to the bottom while on the other hand, the liquid with lighter density less than 1 like oil will floating above.
