Introduction
The operation of the KTFG Series Gas Turbine Meter is based on the measurement of the velocity of gas. The flowing gas is accelerated and conditioned by the meters straightening section. The straightening vanes prepare the gas flow profile by removing. undesired swirl, turbulence and asymmetry before the gas flows to the turbine wheel. The dynamic forces of the flowing fluid cause the rotor to rotate.
The turbine wheel is mounted on the main shaft, with special high precision, low friction ball bearings. The turbine wheel has helical blades that have a known angle relative to the gas flow. The conditioned and accelerated gas drives the turbine wheel with an angular velocity that is proportional with the gas velocity.
KTFG Series Gas Turbine Meter is widely used for measurement of natural gas, coal gas, liquefied gas and light hydrocarbon gas, etc.

Sensor should be installed in the sites where is convenient to maintain, have no vibration of pipe, no strong electromagnetic interference, and hot radiation influence.
The each part of configuration can be chosen in view of the objects measured ,which needn’t all. It is sensitive for turbine flow meter to velocity aberrance and rotating flow, so entering sensor should be the pipe flow developed enough and match the necessary straight pipe or rectifier.
| Upstream component types | Single 90° angle bend | Double 90°angle bends at the same level | Double 90°angle bends at the different level | Concentric reducing pipe | Open whole valve | Open half valve | Downstream side length |
| L/DN | 20 | 25 | 40 | 15 | 20 | 50 | 5 |
If upstream side components of flow resistance are variables, the pipeline length upstream generally is not less than 20D and the pipeline length downstream is not less than 5D. If the installation space does not satisfy these demands, the flow rectifier may be installed between the component of flow resistance and sensor.
