A Pietro Fiorentini diaphragm meter is a mechanical gas volume meter designed to measure the flow of gas (such as natural gas, LPG, manufactured gas, and other non‑corrosive, filtered gases) in low‑pressure distribution networks with high accuracy, reliability and durability. These meters are ideal for residential, commercial, and light industrial applications, helping utilities and end‑users monitor gas consumption and manage billing or flow control processes.

✔ High Accuracy & Quality Control — The measuring module is produced under strict quality checks to ensure consistent performance and accuracy in gas measurement.
✔ Durable Construction — Meters typically feature zinc‑coated steel plate or die‑cast aluminium housings with synthetic diaphragms designed to withstand tough operating conditions.
✔ Low‑Pressure Operation — Suitable for use in low‑pressure gas distribution networks, including residential, commercial, and industrial distribution points.
✔ Wide Gas Compatibility — Works with natural gas, LPG, manufactured gas and other non‑corrosive gases when properly filtered.
✔ Robust Environmental Range — Designed to operate reliably in typical ambient temperatures ranging roughly from –25 °C to +55 °C without loss of accuracy.
✔ Easy Installation & Maintenance — Mechanical design and standardized connection sizes make these meters easy to install and service in gas metering systems.

• Residential gas metering for homes and small properties.
• Commercial metering for offices, shops, hotels, and light industrial facilities.
• Low‑pressure gas distribution networks where accurate volume measurement is needed.

• Metering stations and energy usage tracking systems.

✔ Trusted Italian engineering with decades of experience in gas metering.
✔ Reliable mechanical performance even with variable flow rates.
✔ Cost‑effective and low‑maintenance compared with more complex electronic meters.

✔ Suitable for a wide variety of gas distribution setups, including hydrogen‑ready versions in some models.
