Rotary meters FMR manufactured by Flow Meter Group B.V. in the Netherlands.
The FMR 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 aluminium cartridge allows local repair and on-site cleaning. Gas meter is extremely resistible to pressure shocks and overload of maximum flow thanks to robust design of aluminium casing and measuring cartridge. Measuring cartridge has square impellers, massive shafts and bearings allowing easy replacement without disassemble of measuring cartridge. Self lubricated bearings under normal operation with measuring of dry and clean natural gas have lifetime 15 years. The aluminium casing (body and cover) is designed for working pressures up to 16 bar (PN 16) and 20 bar (ANSI 150 FF) with a safety factor of 5.
An aluminium 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 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 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.
For more information and technical data can be found in the datasheet. (Documents).
ALFA IN corporation is supplier of rotary gas meters FMG to RWE Group in the Czech Rep.
