WATER LEVEL INDICATOR Russian patent published in 2021 - IPC G01F23/04 G01F23/22 

FIELD: measuring sensors.

SUBSTANCE: invention relates to devices for monitoring the level of liquids and can be used to signal the filling of containers with liquids. The water level indicator consists of Element 1 and Element 2. Element 1 is a receiver bracelet consisting of a strap and a case in which a rechargeable battery is located, charged from a magnetic contact, a power button is attached to the battery, when pressed, the LED lights up and power is supplied from the battery to the radio receiver, which is connected to the antenna, with the help of which the signal from the transmitter located on Element 2 is captured, while the radio receiver is connected to vibration and piezo-mechanisms that give sound and vibration signals when a signal from the transmitter from Element 2 is received to the antenna. Element 2 is a transmitter consisting of a housing in which a battery is located, charged from a magnetic contact, a power button is connected to the battery, when pressed, power is supplied to the temperature board with a built-in display and at the same time power is supplied to the radio relay from the plus of the battery, while contacts are installed on the wire, which are closed when immersed in water, which in turn leads to the operation of the radio relay system, which sends a signal through the antenna to the antenna in Element 1, and the current temperature of the liquid is shown on the display.

EFFECT: invention increases the convenience and reliability of the water level monitoring system.
