What is a G25 gas meter?
Accurate and safe, this Elster BK-G25 465mm diaphragm gas meter measures the volume of gas used and sends a pulsed signal directly to your BMS system. Supplied in folded form as co-axial and two-pipe versions, BK-G25 ensures low bearing loads and quiet operation via a pneumatically stopped stroke.
What is a diaphragm gas meter?
Diaphragm meters are displacement meters where the flow channels are designed to guarantee optimum flow 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.
What is Qmax gas meter?
Q max refers to the maximum flow rate. This is the highest flow rate at which a gas meter is required to operate within the limits of its maximum permissible error. Qmin refers to the minimum flow rate. This is the lowest flow at which the meter accuracy will be within the maximum permitted error.

What is a U6 gas meter?
The U6 and SC6 meters incorporate a measuring unit with a two litre cyclic volume designed to accurately meter volumes in all natural gas and LPG applications. The U16 uses two of the same measuring unit to cope with larger flows of the same second and third family gases. Domestic Gas Meters. “U6 Credit Meter.
How does a diaphragm meter work?
Diaphragm meters work using the same principle as rotary meters, consisting of chambers separated by a diaphragm and deformable wall. These chambers fill up and expel gases alternately. The process starts when the gas enters through the inlet in one chamber.
How many types of gas meters are there?
There are four natural gas meter types often used for flow measurement. They are mass flow meters, velocity flow meters, differential pressure, and PD meters.
How do I know what type of gas meter I have?
The first thing to do is establish exactly what type of meter you have. If your meter only has 4 numbers to the left of any numbers in red then your meter is an older imperial-type meter. If your meter has 5 numbers to the left of a decimal point or space then you have a newer-style metric meter.
What are the different sizes of gas meters?

What is a G4 gas meter?
The Metrix G4 Diaphragm gas meter with the distance between the bosses of 152mm is designed for measurement of gas supplied to domestic housing etc, where maximum consumption of gas is equivalent to 6m3/h of air of density of 1,2 kg/m3. This meter is an ideal replacement for a U6 gas meter.
What size is a domestic gas meter?
Typically installed gas meter sizes range from 175 cf/h to 275 cf/h.
How do I know what size gas meter I have?
When a gas utility provider installs a gas meter at a residence, technicians will determine its size based on the total capacity of the home’s gas appliances. The gas meter’s label will indicate its capacity in cubic feet per hour (cf/h). Common meter sizes range from 175 cf/h to 275 cf/h.
How do I know if I need a bigger gas meter?
To determine if your gas meter is undersized, you first have to know the total gas demand for your building. The easiest way to do this is to add up the “British thermal units/hour” (Btu/h) ratings of all the gas appliances. Each appliance will have a date plate with this information, though some can be hard to find.
How many kW can a U6 meter supply?
| Meter Type: Low Pressure (Diaphragm Meters) | Flow Rate kW (kilowatts | Capacity (SCMH) Standard cubic metres per |
| U6 | 0 – 65 kW | 6 m³/hr |
| U16 | 66 – 173 kW | 16 m³/hr |
| U25 | 174 – 271 kW | 25 m³/hr |
| U40 | 272 – 430 kW | 40 m³/hr |
What kind of gas meters are there?
They generally come in two different types; either metric or imperial, with metric generally having five main numbers and imperial having only four main numbers. A metric gas meter will also feature a decimal point to the right of the main numbers that states the part units that have been used.
How often do gas meters need to be replaced?
10 to 25 years
How often should gas meters be replaced? This all depends on the type of gas meter you have, but it can range from 10 to 25 years. Your energy supplier should send you a letter informing you that your meter will need to be upgraded to a more modern model.
