Abstract:
In this research non-contact ultrasonic based method is used for liquid level measurement in a container. A system has been designed and developed to determine the liquid level and show the results on a personal computer. The system contains three main parts, which are mechanical and electronic parts and the programming. The setup can measure the liquid level with the accuracy of 1cm. An ATMEGA8 microprocessor commands to relays and controls the pumps. The pumps are used to change the height of the liquid in the containers to accurately calibrate the sensor and test its operation. The ultrasonic sensor, which is mounted above the vessel, transfers the data to an ATMEGA64 microprocessor for processing and calculating the height of the liquid. The measured level is displayed on a PC.
Here, we have described the problems of installing the ultrasonic sensor on the outer wall of the container; we have verified them by calculating and testing with different sensors and then giving some solutions to deal with this problem. We have used the SRF485WPR ultrasonic sensor to prove the offered solution
