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
Provides wide measuring range for capturing very low and high flow rates
Provides communication interfaces for remote reading
