ITRON Mz100b TURBINE GAS METER 50mm
lFlow rate: from 10m³/h to 100m³/h
l DN50
l Wafer: ISO PN10
ITRON MZ100b TURBINE GAS METER 50MM MZ meters are suitable for both natural gas
and other ltered and non-corrosive gases. They are used to measure low to medium
and high ow, at low or medium, or high pressure. Various additional tting options are
available including an oil pump and a PTFE coating version, making them also suitable
for heavy duty measurement.
ITRON Mz250c TURBINE GAS METER 80mm
l Flow rate: from 16m³/h to 250m³/h
l DN80
l Wafer: ISO PN10
ITRON MZ100c TURBINE GAS METER 50MM MZ meters are suitable for both natural gas
and other ltered and non-corrosive gases. They are used to measure low to medium
and high ow, at low or medium, or high pressure. Various additional tting options are
available including an oil pump and a PTFE coating version, making them also suitable
for heavy duty measurement.
ELSTER QUANTOMETERS
Elster Quantometers are highly reliable gas meters which meet the highest standards. By
using the quantometers in production and heating processes, it is possible to control ow
of gas precisely and therefore optimise the use of energy. They work on the principle of
the rotating turbine wheel. The rotation of the turbine wheel is proportional to the volume
of the owing gas.
The QA quantometers are tted with a 7-digit mechanical totaliser which registers the
volume in cubic meters. Besides the normal registration of the total volume, the QAe
can also display the ow rate, the volume of a key day and the date of the key day.
Meters can be tted with a high and low frequency pulse output. The Quantometers are
available in a number of ow ranges, diameters and pressure ratings. Depending on the
version, a low or medium-frequency pulser and an optical readout or an optical readout
with additional M-bus output is avaliable. All of the Quantometers are DVGW approved.
For special industrial applications, stainless steel versions are also available.

ELSTER DIAPHRAGM METERS
Diaphragm meters are displacement meters where the ow channels are
designed to guarantee optimum ow conditions and a low pressure loss. They
are suitable for measuring natural gas and a variety of technical gases at
up to 0.5 bar. The approved gas temperature range is -20 °C to +50 °C. The
diaphragm meters BK-G 1.6 up to G 100 are tted with a pulse magnet as
standard. This allows to retrot a low-frequency pulser of the IN-Z61 type.
All of the meters are approved for custody transfer measurement by the
German PTB and to EN 1359 by German DVGW.
Domestic Diaphragm Meters, BK-G 1.6 to BK-G6
These meters are available in co-axial or two-pipe versions. The measuring unit
operates on the principle of pneumatic control. This guarantees low noise,
long-term stability and high accuracy and allows the possibility of including
mechanical temperature correction.
Commercial Diaphragm Meters, BK-G10 to BK-G25
These compact meters are available in co-axial or two-pipe versions with
a pressed steel housing. The measuring unit operates on the principle of
pneumatic control. This guarantees low noise, long-term stability and high
accuracy.

MZ METERS
MZ meters are ow meters. The ow of gas turns the turbine wheel, and thus the rotating speed of the turbine is
proportional to the linear speed of the gas. The movement is mechanically transmitted to the totaliser through a
magnetic coupling. The MZ meter is composed of ve main parts;
l A body part containing all the components
l A ow straightener to stabilise and accelerate the ow before the turbine wheel
l A measuring unit including the turbine wheel
l A magnetic coupling to transmit the movement of the turbine wheel to the totaliser
l A totaliser to register the measured gas
