Abstract
A hydrometer device according to an example includes a floating waterproof device container, and a liquid level sensor positioned in the device container to sense an immersion level of the device container when the device container is floating in a container of liquid. The hydrometer device further includes a conversion circuit positioned in the device container to convert the sensed immersion level to a digital value, and a controller positioned in the device container to determine a liquid density value for the liquid based on the digital value.
Claims14
A hydrometer device, comprising:
- a floating waterproof device container;
- a liquid level sensor positioned in the device container to sense an immersion level of the device container when the device container is floating in a container of liquid;
- a conversion circuit positioned in the device container to convert the sensed immersion level to a digital value;
- and
- a controller positioned in the device container to determine a liquid density value for the liquid based on the digital value,
- wherein the controller is to determine a liquid classification for the liquid based on the digital value, the liquid classification comprising a type of the liquid, and
- wherein the controller is to determine the liquid classification using a lookup table that associates liquid density values or ranges with types of liquids comprising gasoline, diesel fuel, water/summer windscreen washer fluid, winter windscreen washer fluid, winter washer concentrate, and diesel exhaust fluid.
An automotive system, comprising:
- a fluid container to be positioned in an automobile and hold a fluid to be used by the automobile;
- a waterproof device container positioned in the fluid container to float on the fluid;
- a capacitive liquid level sensor positioned in the device container to sense an immersion level of the device container;
- and
- a controller positioned in the device container, wherein the controller includes a conversion circuit to convert the sensed immersion level to a digital value, wherein the controller is to determine a liquid density value for the liquid based on the digital value, and wherein the controller is to cause information regarding the liquid to be wirelessly transmitted to a control device in the automobile that is located outside of the fluid container,
- wherein the controller is to determine a liquid classification for the liquid based on the digital value, the liquid classification comprising a type of the liquid, and
- wherein the controller is to determine the liquid classification using a lookup table that associates liquid density values or ranges with types of liquids comprising gasoline, diesel fuel, water/summer windscreen washer fluid, winter windscreen washer fluid, winter washer concentrate, and diesel exhaust fluid.
