A liquid gauge is disclosed. The liquid gauge includes a plurality of holes configured to receive a plurality of liquid droplets of a first size. The liquid gauge also includes a plurality of curved structures configured to form an aggregated liquid droplet of a second size using the plurality liquid droplets of the first size. The liquid gauge further includes a plurality of counting electrodes configured to generate a corresponding electrical signal. The liquid gauge further includes a processing unit configured to count the aggregated liquid droplet of the second size received by each of the counting electrode and also configured to compute a total amount of liquid fall based on the aggregated liquid droplet of the second size.
