GPRS Wireless LPG Flowmeter GPRS Turbine Flow Meter LPG Gas Flow Meter
Description
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 flow meter is widely used for measurement
of natural gas, coal gas, liquefied gas and light hydrocarbon gas,
etc.
Features
