OMEGA’s high accuracy Gas
Turbine Series measures the
volumetric flow of gas through a
pipeline. Gas flowing through the
meter turns the turbine rotor at an
angular velocity which is
proportional to the velocity of the
gas being measured. As the
turbine rotor turns, the rotor blades
pass a non-intrusive pickup coil that
generates an electrical signal,
referred to as a pulse. Each pulse
represents a specific volume of gas
(i.e. ACF/AM3). The totalization of these
pulses results in the total volumetric flow. The total
volume can be converted to mass flow total (SCF or
NM3) using reference conditions and base density, or
by applying various correction techniques. Standard
calibrations for these gas turbine systems are performed at a reference density of 0.1 lb/Ft
calibration certificate (traceable to NIST or other
recognized national laboratory) is supplied with each
meter. Standard calibration includes a calculated
K-factor for gas that is derived from a 10-point
NIST calibration for water. Calibrations at customer’s
actual operating densities can be performed with
special order.
OMEGA’s gas turbine flowmeters offer high accuracy
measurement of gases for a wide variety of applications,
including fiscal measurement, plant cost allocation,
energy consumption/conservation, etc. These gas
turbine systems are suitable for all non-corrosive
gases such as natural gas, air and nitrogen. Special
versions of this series are available for use on
corrosive gases, such as “off-gas” and feature
NACE- MR175 trim and self-lubricated ceramic ball
bearings. Contact OMEGA for further details.

The capacity of a turbine flowmeter is based on the
actual volumetric flow rate and is expressed as actual
cubic feet (ACF) or actual cubic meters (AM3). The
lower limit of operation is a function of the gas density
and velocity.
