2.2.1 Float damping

Float damping is characterised by high standstill times and self-centering. The damping sleeve is made of high performance ceramic or PEEK, depending on the medium and the application. Float damping can also be retrofitted for the user (see Service).

Use of damping

• Generally when CIV and DIV floats are used for gas measurement.

• For TIV floats (H250/RR and H250/HC only) with an operating primary pressure:

EN 1092-1 ASME B16.5 [bar] [psig]

DN 50 ½" ≤0.3 ≤4.4

DN25 1" ≤0.3 ≤4.4

DN50 2" ≤0.2 ≤2.9

DN80 3" ≤0.2 ≤2.9

DN 100 4" ≤0.2 ≤2.9

Nominal size acc. to Operating primary pressure
