Gas Meter Itron ACD 3/4 Inch G1.6 is Itron’s latest generation residential diaphragm meter designed to meet the needs of last growing gas markets worldwide. It combines accuracy and durability in a highly compact casing.
Through our proven know-how in gas measurement, comined with the use pf modern engineering and production techniques, Itron has developed this compact, robust and highly accurate meter, ensuring reduced shipping costs, easier handling and simplified installation.
Application :
The ACD G1.6 residential diaphragm gas meter is typically used for cooking and hot water heating applications requiring accuracy at low to medium gas flow rates. It is designed for use with natural gas, LPG and all non-corrosive gases.
Operating Principle
The movement of the diaphragm is due to the pressure difference between the inlet and the outlet of the meter. The 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 gas to fill the empty side. A transmission gear and a mechanical stuffing box transfer the reciprocating motion to the index.
Key Benefits
- Ready for remote reading and data management
- Ultra-compact design
- Long-term accuracy and reliability
- Robust, maintenance-free meter
- High resistance to corrosion
Construction
The ACD G1-6 meter contains four main parts :
- Measuring Unit
The 0.7 litre measuring unit has high gliding properties to reduce wear on kinematic parts and consists of the following components
– Four measuring chambers, separated by synthetic diaphragms
– A distribution system with a rotating mono-valve
– An outlet pipe
All materials have been selected for their superior resistance to chemicals and gas.
A back-run stop prevents the meter rom running backwards.
2. Casing
A gas-tight casing, highly protected from corrosion. Two different casing materials are available :
– Steel casing
– Alluminium Casing
3. Mechanical Transmission
A stuffing box transmits the movement of the measuring unit to the totalixer.
4. Totalizer
A totalizer is available in cubic meters (standard) or kWh (optional).
Depending on the application, different totalizer versins can be ordered :
– “c” series : mechanical index equipped with a Cyble target for retrofittable AMR communication systems. This Itron standardised meter interface allows the adaptation of different Cyble modules as a communication device. – “0” Series : mechanical index available with a permanent magnet in an index drum. ℃This Itron standardised meter interface allows the adaptation of different Cyble modules as a communication device. – “0” Series : mechanical index available with a permanent magnet in an index drum. ℃
– “0” Series : mechanical index available with a permanent magnet in an index drum.
