MEITWIN XXX
SIZE RANGE:
50-150mm

Main characteristics

  • The main meter and the by-pass meter are arranged one behind the other in the direction of flow.
  • There is no longer any need for the differentiation between the “by-pass meter on the right” and “by-pass meter on the left”.
  • No straight upstream or downstream pipe necessary due to integrated flow straightener (U0D0).
  • Removable metrological unit consisting of the main meter, the change-over valve and the by-pass meter (“3 in 1” concept).
  • A multirange metrological unit allows an easy economical replacement after the validity period of the calibration has expired.
  • Main meter with hydrodynamic balanced rotor.
  • Spring-loaded change-over valve with low headloss and extended lifetime.
  • By-pass meter specified as a piston meter cartridge 612MTW-HRI with plug-in non-return valve, register copper/glass, protection class IP68.
  • Minimum flowrate: 6 l/hour for piston type by-pass meter.
  • Available in body lengths specified as per DIN 19625 and ISO 4064.
