FLOW METER GROUP bv (FMG)

Turbine Gas Meters

The Turbine Gas Meters are robust and designed to perform on the highest level of accuracy. All these meters is the fact they comply with all international standards and are approved for custody transfer even with smallest possible installation length.

The actual flow sensor, an exchangeable cartridge, has a build-in multi stage flow conditioner enabling the meter to be installed with limited straight in- and outlet sections. All tested and proved according perturbation test as per international standards. The cartridge can be pre-calibrated, under both low and high pressure conditions, then exchanged on-site. The cartridge is supported in O-rings and isolated from the body, hence unaffected by any influences of the housing.

FMT-Lx

The FMT-Lx turbine gas meter is an extremely accurate flow meter (MID approved for fiscal use by the NMi) suitable for various types of gas at operating pressures up to 100 bar (1440 psi). The integrated flow conditioner minimized the need for straight upstream piping to just 0 x D.

FMT-Dc

The FMT-Dc turbine gas meter is a special turbine meter (MID approved for fiscal use by the NMi) with two independent measurement units in one body. Therefore the performance of the FMT-Dc is equal to the FMT-Lx, but with two separate indexes the meter can monitor itself which prevents unnecessary maintenance.

FMT-S

The FMT-S turbine gas meter is a unique turbine meter (MID approved for fiscal use by the NMi) combining the performance of the FMT-Lx with the size of a Quanto meter. The integrated flow conditioner minimized the need for straight upstream piping to just 1 x D.

FMT-Q

The FMT-Q turbine gas meter is a Quanto meter which is equal to the FMT-S turbine gas meter series, but without the special flow conditioner. This way the meter can not be used for fiscal use, but is with the low pressure loss perfect for internal gas registrations.

Rotary Gas Meters

The FMG series of rotary gas meters are designed to meet the highest demands of reliable and accurate measurement of gas flow. The meters are MID approved and fully comply with EN12480 and OIML R137. The compact exchangeable aluminium cartridge allows local repair and on-site cleaning.

The robust design of the casing and the cartridge make the meter less sensitive to installation stresses caused by the connecting piping. A significant amount of misalignment of the connecting piping/flanges can be tolerated by the meter without affecting the meter performance by jamming the impellers.

FMR series

The FMG rotary gas meter is a displacement type gas meter. The meters are designed for fiscal use (MID approved by the NMi). The aluminium casing of the FMR (body and front plate) is designed for working pressures up to 40 barg with a safety factor of 4. The square impellers and the improved position of the main bearings and shafts, make the meter less sensitive to overload and pressure shocks.

FMR series (High pressure)

The high pressure rotary gas meter series are designed to meet the highest demands of reliable and accurate measurement of gas flow. The high pressure meters are designed for working pressures up to 100 barg and for fiscal use (MID approved and fully comply with EN12480 and OIML R137 by the NMi). Since the installation of the meter contains a special designed bracket, the exchangeable aluminium cartridge allows local repair and on-site cleaning which is unique for high pressure meters.

Electronic Volume Correctors and Devices

FMG gas meters can be equipped (optional) with two thermo wells and two pressure tapping points. Therefore the gas meters can be supplied and equiped with an Electronic Volume Conversion Device. FMG offers a large variaty in conversion devices so all required data can be provided and the best solution for every project can be assembled.

Refer to the special brochure for more information about the Electronic Volume Conversion Devices FMG is able to supply or contact a local supplier.

FMG can also supply Flow Computers which provide more functions than standard volume conversion devices. The Flow Computers can be used in combination with Rotary Gas Meters or Turbine Gas Meters, so a specific solution for every type of meter can be found.

FMVC series

The FMVC-111 is designed to convert gas volume in operating conditions to gas volume in standard conditions according to the state equation. For that purpose, it reads pulses from a gas meter, and measures gas temperature and gas pressure. The volume corrector will support PTZ, PT, TZ or T type conversions using algorithms for calculation of compressibility factors according to the standards AGA 8-92DC, AGA NX-19 mod, AGA 8-G1, AGA 8-G2, SGERG-88 or

SFC series

The SFC3000 is far more than just a dedicated flow computer. It can operate on a number of levels from a supervisory machine to a stand alone flow computer or as a system component. With its touch screen, VGA display and extensive processing capabilities, combined with simple to use controls and unique operating software it can function as a complete station supervisor integrated into a flow computer housing.
