The rotary gas meter consists of two figure-of-eight rotors that rotate in different directions.
The rotors are installed in the measuring chamber of the cylindrical meter.
In the meter body, the gas inlet and outlet openings are different and on opposite sides.
The rotors are made very precisely, the rotating elements that do not come into contact with each other do not pass measured values between each other media.
This feature ensures the durability of the rotors and the measurement accuracy that occurs due to the wear of the rotors.
Compared to other meters, the measurement accuracy of these meters almost independent of draft, pressure or changing flow, but highly dependent on the purity of the measured gas.
The meters are used in pressure lines from atmospheric pressure to 16 bar.
Measurement chambers of the meter limited by rotors are isolated from each other.
This effect is achieved due to iti n precision manufacturing.
