This two level Liquid Level Sensor is an aid which prevents cups from being overfilled with 2 levels of liquid. The unit simply hangs over the side of a cup or glass with the probes on the inside. Ideal for making a cup of tea or coffee with milk. Simply pour in the hot water stopping when a pulsating tone is heard then pour in milk stopping when a continuous tone is heard. Can also be used as a single level sensor such as for non mixed drinks. Handy magnets on the back of the unit allow for easy storage on fridge or other metal object. Uses a 12V battery.
