Apparatus and method of monitoring the level of a liquid medium in a container

A method of monitoring of a level of a liquid medium comprises:

• a) providing a container, configured to contain a liquid medium therein;
• b) providing an apparatus for monitoring of a level of a liquid medium, wherein said apparatus comprises of:
• I) providing an attachment band disposable on exterior wall of a liquid medium container, said attachment band comprises at least one permanent magnet embedded therein;
• and
• II) providing a free float comprising an electric circuitry comprising:
• i. an electrical power source;
• ii. at least one magnetic proximity sensor;
• iii. an alarming device configured for generating an alert, wherein said alarming device is selected from the group consisting of:
• a LED, flicker, buzzer, IoT device and communication device;
• iv. an actuation module configured to controllably activating said alarming device, wherein actuation of said actuation module is controlled by said at least one magnetic proximity sensor;
• wherein said float free-floating or immersed on top of said liquid so that said float moves laterally and vertically into and out of proximity of said permanent magnets embedded within said attachment band, with variance of said level of said liquid;
• wherein proximity of said float to said attachment band is sensed by said at least one magnetic proximity sensor embedded within said float, when said float is in proximity with said permanent magnets embedded within said attachment band.
