Measuring ranges
Type TME400 turbine meters have measuring ranges of at least 1:20 at atmospheric
pressure (see
chapter 1.4.2.9 Measuring accuracy
). At a higher pressure, the meas-
uring range can be expanded to 1:50. The measuring ranges are between 2.5 and
25,000 m 3 /h (operating conditions), depending on meter size.
The turbine meters with nominal diameter of DN25 and DN40 can be used up to a
maximum of 16 bar. However, there may be restrictions for threaded connections that
are subsequently used.
