The HM gas meters series are designed and manufactured to meet the most stringent requirements of the European Natural Gas Distribution industry.

The HM-iCON combines new generation electronical features with a diaphragm measuring unit. The mechanical register is now replaced by an electronic totalizer equipped with a data transmission interface and a remote firmware update function. The HM-iCON combines integrated temperature and pressure sensors that can be used (by configuration) in order to perform gas volume compensation (this feature is only configurable in factory) of the measured gas volume.

FT 518 is an unbalanced pressure regulator.

This regulator is suitable for use with previously filtered, non corrosive gases. It is a truly top entry design which allows an easy maintenance of parts directly in the field without removing the body from the pipework.

When the built-in token relief valve is active, it prevents undesiderable slam shut trip due to minor internal leakages or ambient temperature variation.

The modular design of FT 518 pressure regulators allows to retrofit either slam shut valve or integral full monitor.

This product is available on selected markets only. For further details, please contact your closest Pietro Fiorentini representative.

Pietro Fiorentini created a completely independent division to perform the periodic verifications, provided for by Italian D.M. n. 93 of 21 April 2017, “Regulation concerning the criteria for the execution of subsequent metrological controls on gas meters and volume conversion devices“.

Pietro Fiorentini inspection agency complies with the requirements of UNI CEI EN ISO/IEC 17020: 2012, and is therefore accredited as a Type C Inspection Body for the periodic verification of gas meters and volume conversion devices associated with gas meters. This accreditation allows to perform maintenance activities at the same time of the periodic verification activity.

Pietro Fiorentini inspection agency is structured to respond to every need throughout the national territory; in fact, thanks to three Territorial Units located in the North-West, North-East and South, it can easily reach any location around Italy.

The Organization bases its activity on objective evidence obtained through an impartial, fair, valid and reliable evaluation, not influenced by other interests and without prejudice.

The organization is structured with tools that allow the execution of all activities with a very high degree of automation; moreover, each inspector is provided with his own digital electronic signature with which he validates the verification reports; thanks to an automated process, the documents are transferred to the attention of the Technical Manager of the Body who checks them and validates them with his own digital electronic signature in real time.

All the activities carried out by the inspectors can be evidenced by photographic documentation which is always filed together with the relevant inspection report.
