Operating Principle:

The TBQSe quantometer is a turbine gas meter that registers the operating volume using a nine-digit electronic index. The flow ofthe measured gas causes the turine rotor to rotate.  As the gas passes throuogh an annular cross-section, it is accelerated and directed onto the smoot-runnng aluminum rotor. The number of rotations is proportional to the measured gas volume, and the frequency of rotations is proportional to the actual gas flow. The rotation of  the rotor is transmitted by a magnetoresistance sensor from the pressurized gas area to the electronic index located in the atmospheric envioronment. The CPU receives the high-frequency signal from the magnetoresistive sensor and calculates the gas flow and gas volume under operating conditions.  lf the optional electronic volume corrector function is installed, the gas flow and gas volume under standard conditions are calculated according to AGA NX-19. The calculation can be based on fixed temperature and pressure factors or on optionally  installed temperature and pressure sensors. The TBQSe is designed to allow one external temperature transmitter and one external pressure transmitter to be installed directly in the meter.
