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.
To reduce transportation cost, optimize the corrosion protection and improve safety in handling, the FMT-Q series of turbine meters are also available with low weight aluminium meter bodies. As an example, the weight of a 12” (DN300) ANSI300 FMT-S is less than 45 kg.
The operation of the FMT-Q series of turbine meter is based on the measurement of the velocity of gas. The flowing gas is accelerated and conditioned by the integrated flow conditioner. The flow conditioner prepares the gas flow profile by removing undesirable swirl and asymmetry before the gas flows over the freely rotating turbine wheel. The dynamic forces of the flowing gas cause the rotor to rotate. The turbine wheel is mounted on the main shaft, with high-precision, low-friction ball bearings.
The turbine wheel has helical blades that have a known angle relative to the gas flow. The gas flow drives the turbine wheel at an angular velocity, which is proportional with the gas velocity. Using a gearing mechanism, the rotating turbine wheel drives the mechanical counter.
The unique FMT-Q turbine meter is suitable for internal gas measurement of all non-corrosive gases such as natural gas, propane, butane, air, nitrogen, hydrogen, etc. for low and high operating pressures. Special constructions can be supplied for use under extreme conditions like high temperatures or corrosive gases. Standard FMT-Q bodies up to 8” (DN 200 mm.) ANSI150 or PN10/PN16 come with threaded flanges. Larger Sizes or higher pressure ratings up to 24” ANSI600 are available in steel.
The FMT-Q has a length of 1.5 x DN for small sizes and just 1 x DN for larger sizes. For flange ratings up to ANSI300 and PN40, the body is available in aluminium (steel on request). Due to the extremely low weight of these aluminium bodies, the meter can be transported easily and exchanged without special equipment.
Since the FMT-Q is equal to the FMT-S (but without the multi stage flow conditioner and the compliance to all international standard) the FMT-S brochure can be consulted for more information.
