AUTOMATED LIQUID LEVEL MONITORING METHOD AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC G01F23/18 

FIELD: physics.

SUBSTANCE: invention relates to automated wireless control of liquid level height and can be used for remote monitoring of liquid level in water reservoirs, on streets, in rooms, wells, tunnels, reservoirs and other places. Device 1 comprises tube 5 with one open end 6, inside of which sealed partition 9 is installed with formation of two cavities 10, 11 in tube. In first cavity 10 the first air pressure sensor 12 is installed. In second cavity 11 there installed is second air pressure sensor 13, radio transmitting device 16, control controller 15 with software connected to radio transmitter 16 and each air pressure sensor 12, 13, power supply 14 connected to control controller 15 and radio transmitting device 16. Tube 5 has through hole 17 on section between sealed partition 9 and closed end 7.

EFFECT: high accuracy, reliability, information content and reliability of information on change in liquid level, timely detection of change in liquid level and possibility of remote automated monitoring, eliminating the need to lay wire communications, enabling long-term operation without the need for maintenance.
