Development of Automatic Fuel Meter Trainer Control System Using Microcontroller

The actual fuel consumption measurement tool already exists, but the work system in calculating fuel consumption from this is done by using visual sensing parameters, namely conditioning the motor rpm at a certain position and calculating how much fuel volume is reduced in units of time using a stopwatch. This method causes the reading process to be inaccurate and still depends on the human accuracy itself which is influenced by factors of concentration, fatigue, reading response, and others. Therefore, an Automatic Fuel Meter is designed to be the solution to this problem. The purpose of this research is to design and create an automatic control system that can calculate fuel consumption on the trainer using a microcontroller with available mechanical trainers. The results of this study are an Automatic Fuel Meter using an Arduino Nano controller as a controller, an infrared sensor is used as a timer or timer for fuel consumption. The work algorithm carried out in calculating fuel consumption has 3 stages, namely the filling stage, the reading stage, and the data calculation stage. The Auto Fuel Gauge can calculate fuel consumption with a sought precision value of a known standard deviation of 0.194366778. So that the percentage value of the coefficient of variation is 1.7057198596%~1.7%. Response time from the infrared sensor takes 0,202083 seconds on the test on pertalite fuel and 0,200521 seconds on Pertamax fuel.
