CGT series turbine gas meters are flow meters designed to measure quantity of gases. The meters are mainly used for gas flow ranges from 6.5 up to 6500 m3/h. The CGT series gas meters are applied in measurement systems where high accuracy is required:
-
transportation of natural gas
-
primary and secondary measurements
-
control metering of the natural gas and non aggressive technical gases in industry
-
flow measurement for technical purposes
The turbine gas meter measures the quantity of gas basing on the flow principle. The gas flows through an integrated flow conditioner, which distributes the flow proportionally in the annular slot and guides it to the turbine wheel. The wheel is driven by the gas flow, and the angular velocity of the rotation is proportional to the gas flow rate. The energy consumption, perceived as pressure loss, is reduced to absolute feasible minimum due to the application of the low conditioner, highest precision ball barings, most accurate tolerances of all measuring parts and their proper alignement. The rotary motion of the turbine wheel is transferred mechanically by gear wheels, and the incorporated gas tight and hermetic magnetic coupling, to the index unit, which is mounted on the top of the body, and shows the operating volume on the totalizer.
The basic components of the COMMON CGT series turbine gas meter are as follows:
-
pressure resistant meter body
-
inlet flow conditioner
-
measuring cartridge with the turbine wheel
-
magnetic coupling as the transferring element between measuring cartridge and the index
-
index
-
lubricating system (some meters are provided with self lubricating bearings)
