Designed in conformity to the highest accuracy and reliability standards, the MM mechanical meter range by Pietro Fiorentini is charaterised by the zinc-coated steel plate external case. Its high accuracy is determined by the metering module, which is submitted to several and strict quality control procedures during the whole production process.

Pietro Fiorentini commercial gas meters can be used with natural gas as well as manufactured gas, LPG or other non-corrosive and preliminarily filtered gases. The meters are designed to operate in low pressure gas operations.
