Commercial Gas Meters
Types and sizes of commercial gas meters — diaphragm, rotary, turbine and ultrasonic — meter installations, regulators, volumes and who is responsible for what.
The meter is where the gas transporter's network ends and the consumer's installation begins. Its type and size determine how much gas the building can draw, the meter volume used in testing and purging calculations, and who must be called when something goes wrong.
These guides explain the meter types found on London commercial sites, how they are sized and badged, and what a commercial gas engineer can and cannot do around the meter.
