Residential Diaphragm Gas Meter

Product Description

We are one of the well known dealer and domestic supplier of Residential Diaphragm Gas Meter. We are certified dealer of Itron. The RFL G6 is a compact residential gas meter designed to measure accurately volumes of natural gas, LPG and all non-corrosive gases.

 

Application

 

The RF1 G6 long-term metrology stability offers the solution of choice for very high residential consumption or Gas repartition applications.

 

Metrology

 

The RF1 G6 gas meter meets strict metrological requirement such as O.I.M.L and EN 1359 as well as DIN, PTB, DVGW and KVGN.

 

The RF1 G6 is a combination of proven gas meter concepts:

● Reciprocating Plastic diaphragm

● Crank- Controlled and oscillating slides

● Robust and tight connections between components

● Use of Precise, light- weight and noise-free plastic parts

 

During the preliminary test control on the sonic nozzle test benches, all meters are tested at Qmin, 0.2 Qmax and Qmax.

Operating Principle

 

The RF1 G6 is a positive displacement diaphragm gas meter with a stand –alone twin chamber measuring unit.

The twin chambers are each fitted with a flexible and gas-tight diaphragm which is moved by the differential between the inlet and outlet pressure. The gas enters one side of the diaphragm pan while on the other side it comes out through a separate port on the valve. When one side is full, the sliding valve moves on to the next position, allowing the gas to fill the empty side. A transmission gear and a magnetic coupling or stuffing box transger the reciprocation motion to the mechanical retrofit able index.

The measuring unit is housed in a robust gas- tight casing.

 

Construction

 

1 – Connections

- Moduled Connections ensure optimum resistance to corrosion

- Material Protected against corrosion (500h salt spray test)

- Available in different versions (DIN 3376).

 

2 – Backflow Flap

(Option and two-nozzle only)

- Available with and without backflow flap

- Protects against the backflow of gas.

 

3 – Body

- Made from aluminum – coated sheet steel, i.e. protected against corrosion

- Additional coating with solvent – free paint integrated crimp

- Alternatively in sturdy aluminum casing fro High pressure application.

 

4 – Back run stop

Prevents the meter from running backwards

 

5 – Crimped Body

-Crimped version for PN 0.1 – PN0.2 – Pn 0.5

-No water residues due to integrated crimp

- safe, DVGW – approved sealing material.

 

6 – Plastic Measuring Unit

- Two – litre measuring unit

- Good recycle ability due to the use of the same classes of plastic ( where possible)

- Resistance to chemicals and gas

- High gliding properties to protect against the wear of moving parts

- Optimum long – term functioning

 

7 – DIN 3374 Counter

Protected against fraud:

- by a stable, sheet metal, retention plate

- by its labyrinth shape.

- tampering is indicated by markings on the type plate.

 

- Dirt Resistant

Resistant to fine dust IP 54

 

- Legible Counter

- Broad reading angles

- Customer – specific, type plates available, e.g. bar code.

 

- Pluse Generator (Option)

- Available with a permanent magnet in counter roller

- Can be refitted with a pulse transmitter (read switch)

 

Quality Assurance

 

 The gas meter – produced in accordance with DIN EN ISO 9001/BS 5750 requirements- guarantees quality, accuracy and long-term stability.

Environmental Aspects

 

Actaris is increasingly concerned with environmental issues. In the development of the RF1 G6. Environmental aspects have been taken in to account.

● Use of an environment-friendly coating process ( water-based paint)

● Lead-free sheet metal

● Weight reduction

● Low- noise

● Plastic parts of the same class as far as possible (recyclable, all plastic parts are marked accordingly)
