INDICATION OF LIQUID LEVEL Russian patent published in 2019 - IPC G01F23/22 G01F23/24 G01K13/00 B41J2/175 

FIELD: measurement.

SUBSTANCE: invention relates to measurement equipment and can be used for measurement of liquid level in container. According to the proposed solution, a sequence of heaters is maintained at different depths in the volume. Provided is a series of temperature sensors supported at different depths in said volume. Temperature sensors output signals indicating heat dissipation from heaters to indicate fluid level in volume. Sequence of heaters and the sequence of temperature sensors form a sequence of packets located in an array of packets spaced along the length. Each corresponding packet in the sequence of packs contains a corresponding heater and a corresponding temperature sensor, which are located one above the other in corresponding different layers above the above one and the same surface of the strip.

EFFECT: technical result is to improve the information content of the received data.
