This device is designed to give people with sight problems an alternative method of telling when sufficient liquid has been poured into a cup, glass or other container.
There are two different devices. One an audible liquid level indicator and another one, a vibration liquid level indicator.
The devices detect two different levels of liquid; An intermittent tone or vibration indicates cup is nearly full; continuous tone or vibration indicates it is full.
Replacement batteries are available from RNIB (Product No CP08).
