Ultrasonic Gas Meters

In gas pressure reduction and metering plants it is good practice to protect pressure regulators, valves, meters and all other components from the solid particles inside the gas, if any.

Pietro Fiorentini filters are designed with this purpose in mind: they are manufactured in different types and sizes in order to meet all the needs. They are equipped with nipples for the assembly of the several accessories. They are designed to be sturdy and may be easily installed and maintained. The filtering element is able to filter the solid particles with filtrations up to 5 μm.
