A fuel meter is a device used to measure the amount of fuel remaining in a fuel tank, commonly found in vehicles or various types of equipment. The fuel meter typically displays a visual reading on the dashboard or control panel, allowing the driver or operator to monitor the fuel level in the tank. It usually consists of a sensor inside the tank that detects the fuel level and converts it into a signal displayed as a percentage or a point on a gauge. The fuel meter is an essential tool for ensuring smooth and safe operation, helping to avoid unexpected fuel depletion and allowing for efficient fuel management.
