This research paper is about the design and implementation of a liquid level detector using ultrasonic sensor that utilizes high speed microcontroller (PIC16F887) as well as other instrumentation required. It utilizes water as its process and shall be measured from a calibrated reservoir using ultrasonic sensor for measuring the level of the process in the calibrated reservoir and displaying it using 16x4 Liquid crystal display. This device is applicable in processing industries where liquid measurement is of importance.eg breweries, oil and gas industries.
