The M4com is a compact residential diaphragm gas meter designed to measure accurately volumes of natural gas, LPG and all
non-corrosive gases.
M4Com is a residential gas meter which is manu-
factured by MANAS with the technology transfer
of Gallus2000. Gallus2000 has been produced by
Schlumberger / Actaris / Itron more than 60 milli-
on units installed in 30 years. From now on it will
be distributed to worldwide users as M4Com
under Itron licence.
M4Com is designed for measurement of natural
gas, hydrogen blended natural gas, LPG and all
non-corrosive gas fluids.
M4Com “c” series totalizer offers an inductive
pulse measurement technology which offers,
100% reliable and accurate measurement
against all kind of magnetic tampering, ideal for
AMR applications.
IMPORTANT BENEFITS
- Operational efficiency with remote reading infrastructure
- Compact design, easy installation
- Reliable and maintenance-free design
- Internal RFID Tag application (Smart-Tag)
- Suitable for use with hydrogen blended gas
Gas enters one side of the diaphragm plate, while on
the other side it sluice through a separate port on the
valve. When one side is full, the rotating mono-valve
moves on to the next position, allowing the gas to fill
the empty side.
A transmission gear and mechanical coupling or
stuffing box transfer the reciprocating motion to the
mechanical, retrofittable index.
The measuring unit is housed in a robust, gas-tight
casing.

Construction
1- Measuring Unit
The measuring unit has 1.2 dm
volume. It was manufactured with the
materials which has the least surface
roughness to provide high endurance
for reducing wear and increasing the
life time.
Measuring unit consists of bellow
components
- Measuring unit body contains four measurement chambers seperated by synthetic diaphragms
- A distribution system with a rota- ting mono-valve
- An outlet pipe
High-tech design tools have been used
in the design of the fixed-stroke,
long-proven measuring group mecha-
nism and high-quality mechanical
automation has been achieved.
M4Com provides a perfect stability
and accuracy of measurement through
its whole lifetime due to unique design
of measurement mechanisms and long
life synthetic diaphragms used in mea-
surement chambers.
All material used for production of
M4Com meter were selected to provi-
de an outstanding endurance for
chemicals and gases allowed to use.
Measuring unit was designed to
prevent the reverse gas flow in cases
of meter tampering.
2- Casing
Meter casing has been manufactured
with steel material. Body has withs-
tand high performance in 500 hours
salt fog spray test.
The extreme strength of the case joint
is achieved by rolling the belt and com-
pressing the flanges into contact with
a seal and applied between the faces.
This forms a joint which is both gas-hi-
ght and fire-resistant.
3- Mechanical Transmission (Stuffing Box)
A stuffing box transmits the movement
of the measuring unit right to the tota-
lizer.
4- Totalizer (Record Mechanism)
Totalizer records the consumptions in
cubic meters. Totalizer comes with an
IP54 protection class. Two different
totalizer versions are provided depen-
ding on requirements.
- “c” Series Totalizer:
C series totalizer type has been deve-
lopped in order to provide retrofittable
communication infrastructure in AMR
applications. The totalizer has inducti-
ve pulse production technology.
Thanks to this infrastructure, meter is
converted as a smart meter by using
plug & play wireless M-Bus, GPRS,
NB-IoT, LoRa based communication
modules.
- “o” Series Totalizer:
The numarator type provides an LF
(low frequency) pulse by a magnet
fixed to index drum
