FMG Rotary Piston Displacement Type Meter for Dry Gas

In Stock

The FMG series of rotary gas meters is designed to meet the highest demands of reliable and accurate measurement of gas flow. The meters fully comply with the EN12480 and OIML R137. A compact exchangeable aluminum cartridge allows local repair and on-site cleaning. Installation stresses caused by connecting piping are minimal due to the robust design and construction of the casing and cartridge. The aluminum casing (body and cover) is designed for working pressures up to 21 bar (300 psi) with a safety factor of 5. Square impellers and improved positioning of main bearings and shafts makes the meter less susceptible to overload and pressure shocks.
An aluminum index and protection of the LF pulsers with the associated magnets helps prevent manipulation of the meter by externally applied magnets or other external forces. Tampering of meters with strong neodymium magnets is a major concern of utility companies in many parts of the world.
This type of manipulation is very difficult to detect and or prove, therefore, prevention of such actions is the best cure. Further, in order to be prepared for the “smart grid”, the index can be equipped with an intelligent encoder. A unique proprietary oiling system, where-by the oil is distributed directly to the timing gears by means of a disc, eliminates oil loss at high impeller speed and will lubricate the timing gears at very low loads. All plugs and oil sight glasses are in the front of the meter, allowing the meter to be installed in very compact installations.
