This allows for operational control of its consumption and significantly increases the consumer properties of the device. Ge")

Due to the fact that the gas pressure reducer, flow meter, inlet, intermediate and outlet pipelines are located in the housing, the isolated content of the gas pressure reducer, flow meter and pipe fittings of the device in a separate housing is achieved, which prevents mechanical damage and theft, and (Z also protects against atmospheric precipitation. 3o Due to this, the reliability and safety of operation of the device is significantly increased. c

The device has other distinctive features that complement and characterize the invention in certain cases of its implementation and are used to improve its technical properties.

In the device for supplying gas to the consumption system, according to the invention, the front wall of the case is made with the possibility of removal and with an inspection window located opposite the window of the counter-flow meter. With 70 Such an improvement allows for visual operational control and accounting of gas consumption in the gas consumption system, which also significantly increases the consumer properties of the device.

From" In the device for supplying gas to the consumption system, according to the invention, slots are made in both side walls of the case.

This improvement allows for natural ventilation of the housing and reduces the concentration of gas in it in case of its possible leakage in the places of connection of the gas pressure reducer and the meter-flow meter with pipelines, and that significantly increases the reliability and safety of the operation of the device. 4! From the state of the art, the applicant has not identified technical solutions that coincide with the distinctive features of the proposed invention, on the basis of which it can be concluded that the claimed device has an inventive level. and The given features are not mandatory, but, in the opinion of the applicant, are better in solving the technical (Te) 20 task and achieving the technical result.

At the same time, the possibility of another equivalent implementation of the proposed device within the scope of the essence of the proposed invention is not excluded.
