DRIER FILTER PURGE SYSTEM Russian patent published in 2024 - IPC F17D5/00 G06F9/00 

FIELD: pipeline transport.

SUBSTANCE: invention can be used for control and timely removal of moisture from the inner cavity of the drier filter. Technical result is achieved by a system consisting of a control unit and an information transmission unit, connected to each other via a radio channel or by a wire method and consisting of separate housings with printed circuit boards and central processors located inside them, at that, valves with electric drive, level indicator are connected to outputs of central processor of control unit through galvanic isolation module, temperature sensor, pressure sensor are connected to analogue bus, transceiver, voltage controller—to digital bus; a transceiver for collecting data from the control unit, a module for transmitting data with the Modbus RTU protocol over RS-485 and RS-232 interfaces are connected to the digital bus of the central processor of the information transmission unit through the galvanic isolation module, a jumper and an information display are connected to the discrete output to provide visual control of the transmission of information between the control unit and the data transmission module, voltage conversion module is connected to the printed-circuit board through a switch-on button.

EFFECT: automation of processes and minimization of risks of life and health hazards of an employee when performing work on bleeding.
