A gas meter works by measuring the force of the moving gas in the pipeline. The dials turn faster as the flow of gas increases.
How does a diaphragm gas meter work?
The diaphragm gas meter is a positive displacement meter, also known as a PD flow meter or volumetric flow meter. The gas flows into a meter inlet or chamber of known capacity, which has an oscillating diaphragm. The section fills and empties the gas, and the volumetric flow rate is determined with each cycle.11 Jun 2014
Read the dials from left to right. If the pointer is between the two numbers, always take the lower number. If the pointer is directly over a number, write down that one. If the pointer falls between 9 and 0, write down 9 and reduce the reading you've already taken for the dial on it's left by one.
Do gas meter readings go up or down?
A gas dial meter has 4 or more dials. Each one turns to point to a number between 0 and 9. Each dial on your meter will turn in the opposite direction to the ones next to it. If the pointer is between two numbers, write down the lower number - if it's between 9 and 0, write down 9.
How do you calculate kWh from gas meter reading?
- Take a meter reading, and then subtract the new meter reading from the previous reading to work out the volume of gas used.
- Convert from imperial to metric by multiplying the units by 2.83.
- Multiply by volume correction factor (1.02264)
- Multiply by calorific value (40.0)
Can gas meters be wrong?

How does a modern gas meter work?
Gas. A gas meter simply measures the volume of gas that passes through it. Older gas meters measure the volume in units of 100 cubic feet (ft3) and newer meters in cubic metres (m3). The suppliers systems hold the meter details and so can accurately calculate the volume of gas used.
