A digital gas meter measures the volume of gas being used, in the same way that a traditional meter does. The benefit of a digital meter is that it can communicate the meter reading via a digital communication network, rather than requiring a person to manually read the meter. In the future, this technology could alleviate issues associated with estimated bills (which can happen when traditional gas meters cannot be easily accessed to read), as well as give customers increased visibility of their gas usage.
The trial involved replacing a small number of existing gas meters with digital gas meters to evaluate different types of digital metering technology.
