TURBINE
METERS / QUANTOMETERS
|
|
|
|
Turbine meters
and Quantometers are flow meters which display the volume
flowing through the device in actual cubic meters. The
incoming gas is accelerated through the inlet body and
strikes the blades of the turbine wheel. The revolutions
of the turbine wheel are transferred to an 8-digit roller
counter via a multi-stage gear and a magnetic coupling.
Turbine meter are used for official metering and billing
purpose (custody transfer). Quantometers are short-pattern
turbine meters with a length of 1.5 x DN. From a metering
point of view and in terms of material, both types of
meters are suitable for use with combustible gases in the
field of energy supply as well as with a variety of
technical gases in industrial applications. All turbine
meters have an EU approval and are registered with the
DVGW.
