Products Siensor D107

The Siensor D107 liquid level sensor is an intelligent device designed for accurate measurement of fuel level in vehicle tanks and stationary reservoirs (diesel generators, boiler installations, oil storages, etc.). Siensor D107 measures fuel level and transmits data to the terminal via RS-232 or RS-485 interfaces which is displayed in litres or percentage.
