DEVICE FOR MEASURING GAS FLOW Russian patent published in 2023 - IPC G01F1/64 

FIELD: measuring gas flow.

SUBSTANCE: device consists of an inlet fitting “gas inlet”, a coulometric cell, a microammeter, a direct current source and an output fitting “gas outlet”. The coulometric cell contains electrodes in form of non-contacting helical wound spirals made of plastic or rhodium wire, placed in the channel of a tube made of fluoroplastic or glass, and a film of partially hydrated phosphorus anhydride P₂O₅ is applied to the electrodes and the bearing surface, and the device is designed to calculate gas consumption using the formula Q = (Io·E_H2O)/V, Io – electrolysis current of the coulometric cell, E_H2O – electrochemical equivalent of water, V – gas humidity.

EFFECT: elimination of the need to operate the device for measuring gas flow at high temperatures.
