MeiTwin Water Meter

Sensus MeiTwin water meter is a compound meter for:

• Measurement for billing of cold potable water up to 50 °C at high flow rates as well as very small flow rates for extremely wide spread flow profiles.
• Measurement of medium and high flow rates
• Measurement of extremely low flow (e.g., in light load period)
• Leakage control

The MeiTwin is a versatile solution, specifically designed to bridge the gap between high-volume pumped pipes and extremely low flow rates. Its superior sensitivity makes it an essential tool for active leakage control and district metering, allowing utility managers to monitor network health with confidence. With the MeiTwin, you gain a robust, all-in-one system that maintains accuracy where standard meters might fail.

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
