HM is the smart meter by Pietro Fiorentini which combines the new generation electronic features with a diaphragm metering unit. The mechanical register is replaced by an electronic totalizer equipped with a data transmission device and a remote firmware upgrade function.
This device combines a temperature and pressure sensor which compensate for the measured gas volume. It is mainly used in low pressure natural gas distribution networks.
