Abstract

In industrial environment, Ultrasonic level sensors are also affected by the changing speed of sound due to moisture, temperature, and pressures. Correction factors can be applied to the level measurement to improve the accuracy of measurement. Turbulence, foam, steam, and changes in the concentration of the process material also affect the ultrasonic sensor’s response. Turbulence and foam prevent the sound wave from being properly reflected to the sensor, steam and chemical mists and vapours distort or absorb the sound wave and variations in concentration cause changes in the amount of energy in the sound wave that is reflected back to the sensor. To overcome these problems, the ultrasonic water level sensor detection with the 45° cut pipe insertion, the ultrasonic improvement method for water level control and PI control scheme for continuous water level monitoring and control is implemented. Before the systems implemented, a few steps of procedure have to be followed to ensure the development of Continuous Water Level Control Using Ultrasonic Sensor With 45 Degree Cut Pipe Insertion conducted systematically. The MyRIO is used as the controller to control the system. The control valve and the AC water pump is used as the control element. As result, for this project is the process of water level using Ultrasonic Sensor will give feedback to controller when the yield measurements is that of evaluating the time taken for the sound wave to travel from transmitter towards the tank and reflects the sound wave back with the liquid level interface in the tank.
