Commercial & Industrial Compound Water Meter with Wide Spread Flow Profiles
The MeiTwin is a compound meter for cold water up to 50 °C that measures high flow rates and very small flow rates for extremely widespread flow profiles.
Product Features
- The main meter and the bypass meter are arranged one behind the other in the direction of flow
- No need to differentiate between the “bypass meter on the right” and “bypass 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 changeover valve and the bypass meter (“3-in-1” concept)
- Main meter with hydrodynamic balanced rotor
- Spring-loaded changeover valve with low headloss and extended lifetime
- Bypass meter specified as a piston meter cartridge 612MTW-HRI 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
- A multirange metrological unit allows an easy economical replacement after the validity period of the calibration has expired
- Is ideal to use in fire service pipes
Benefits to you
