Installation conditions:

The FMT-L meter can be equipped with two different flow straighteners. When the large one is installed a straight inlet pipe of 1xDN is applicable. With the small one installed a straight inlet pipe of 5xDN shall be applied.

The FMT-S can only be equipped with the large flow straightener, and therefore needs a minimum of 1xDN straight pipe length in front of the inlet.

The FMT-Lx meter has no installation requirements concerning straight inlet tubing. The inlet flow straightener is identical to the FMT-S configuration due to the fact that the FMT-Lx and FMT-S have identical cartridges.

The FMT-Dc meter consists of two FMT-Lx cartridges in one housing. The same installation conditions and flow straighteners are applicable for the FMT-Dc as given for the FMT-Lx.

The necessary straight pipe length is stated on the name plate of the meter.

Any components which could affect the gas flow must be avoided within the prescribed inlet pipe length. The inlet pipe must be designed as a straight pipe section of the same nominal diameter as the gas meter.
