Designed in conformity to the highest accuracy and reliability standards, the MM mechanical meter 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.

This device can be used with natural and manufactured gas, LPG or other non-corrosive and preliminarily filtered gases, this device is strongly recommended in low-pressure gas distribution networks.
