Digital fuel level indicator is installed on the dashboard of your vehicle and designed for permanent visual control of fuel volume in the tank by the driver. Digital fuel level indicator is connected to digital fuel level sensor, and indicates measured level via RS-232 or RS-485 digital interfaces. The device can operate both in passive mode (along with GPS tracking device which reads data from fuel level sensor) and in active mode, sending requests to sensor independently. Sensor has “filling” mode, which allows to control volume of fuel, filled in vehicle tank. Indicators weight does not exceed 90 g.
