MeiTwinRF Water Meter

Overview Solutions Documentation & Tools


The MeiTwinRF with MID approval is a compound meter with integrated radio for measurement of high flow rates as well as very small flow rates for extremely wide spread flow profiles.

Benefits to you

  • Provides a wide measuring range for capturing very low and high flow rates
  • Provides communication interfaces for remote reading
  • Is ideal to use in fire service pipes
  • Secured encrypted data transmission
  • A multi-range metrological unit provides an easy economical replacement after the validity period of the calibration has expired
Product Features
  • Registers with integrated radio communication and data logger
  • Radio communication with different frequencies
  • The main meter and the bypass meter are arranged one behind the other in the direction of the flow
  • There is no longer a need to differentiate between the “bypass meter on the left” and the “bypass meter on the right”
  • No straight upstream or downstream pipe is necessary due to a integrated flow straightener (U0D0)
  • Removable metrological unit consisting of the main meter, the change-over valve and the bypass meter (3-in-1 concept)
  • Main meter with hydrodynamic balanced rotor
  • Spring-loaded changeover valve with low head loss and extended lifetime
  • Bypass meter specified as a piston meter cartridge 612MTW-RF with plug-in non-return valve, register copper/glass, protection class IP68
  • Minimum flow rate: 6 l/hour for piston-type bypass meter
  • Available in body lengths specified as per DIN 19625 and ISO 4064



  • Spool piece for extension of meter casing as per DIN 19625
  • Port for ¼” pressure sensor
  • SensusRF integrated technology providing the advantages of both uni and bidirectional system architecture
