METHOD AND APPARATUS FOR REMOTELY MONITORING LIQUID FOOD PRODUCTS

摘要

A device for monitoring the temperature and level of liquid food in a container is provided. The device includes an upper base and a lower elongate housing member. A plurality of temperature sensors are located along the length of the elongate housing member. The device may include a retaining lip which allows the device to be hung over the edge of a food container, with the elongate housing member extending down into the liquid food. Signals received from the individual sensors can be used to determine both the temperature of the liquid and the level or volume of the liquid in the container, using the known distances between the individual sensors. Information regarding the liquid temperature and level can then be transmitted from the monitoring device to an external receiver. The device may also comprise an energy harvesting device which converts heat energy from the liquid into electrical energy.
