A gas meter (10) has electrically powered gas measuring means (12) powered by the conversion to electrical energy of chemical energy from a portion of the gas. The meter includes a control valve (17) which draws off a portion of the gas, leading to a flameless combustion chamber (16). A thermoelectric device (22) converts the heat of combustion to electrical energy for running of the meter via a charge storage device (18). |
