Custom Gas Flow Meter Manufacturer, Lpg Gas Flow Meter

Operating Principle

The operation of the International 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 lo (he 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.

Description

The Gas turbine flow meter in the secies LWQ are specially designed for use in natural gas. compressed, air and other fluid measurement.
And the volume and mass flow rate are available.
