Monitoring System Volume of Crude Palm Oil on Vertical Tank Using Ultrasonic Sensor and Solenoid Valve

Abstract

Abstract During this time to find out the volume of Crude Palm Oil (CPO) in the palm oil mill, it was monitored every day on the vertical tank manually using a sounding meter. Monitoring data taken manually is less accurate and requires more time and manpower. So that this weak monitoring data can cause losses if there is oil loss in the tank. Therefore, research aims to help control vertical tanks and can detect any loss of CPO that can harm the company. This research uses data obtained by an ultrasonic sensor connected to a microcontroller and installed solenoid valve on the tank discharge faucet. Data received by the microcontroller is then sent to the server and then stored in the database to be retrieved visually on the monitoring system dashboard. The test results show that the system built can facilitate monitoring of CPO volume in vertical tanks.
