How to Design an Automatic Fuel Level Monitoring-Circuit System in Gas Station Tank
Here we find an article that explains you about how to design a system that will measure the level of fuel in the tank (maybe gas station) and send it automatically to computer-monitoring system. Below is the circuit diagram of the monitoring device. The circuit will need a 240v supply which will step-down to 24V by a transformer and further be rectified using diodes (IN4007) to DC voltage. According to the article, you will need such 470µ… 2, 70.5, 2, 10, monitoring: 6 circuit: 4 voltage: 4
