High Pressure

The FMT-Lx high-pressure turbine gas meter is an extremely precise flow meter for various gas types with operating pressures up to 100 bar (1440 psi) (MID approved for legal use by NMi). The integrated flow regulator reduces the need for straight upstream piping to 0 x D.


The FMT-Lx series turbine meters are designed to perform at the highest level of accuracy. The meters comply with all international standards and are approved for legal measurement. The actual flow sensor is a replaceable cartridge with an internal multi-stage flow regulator, allowing the meter to be installed without straight inlet and outlet sections. All these meters are tested and approved through perturbation tests conducted according to international standards.


The cartridge can be pre-calibrated under both low and high-pressure conditions and then replaced on-site. The cartridge is supported within O-rings and isolated from the body, so it is not affected by any forces on the casing. The short-length cartridge allows larger cartridges to be used in the meter body. The approved maximum capacities of these meters are extremely high and comparable to ultrasonic meters’ capacities.
