AMT VP SERIES AMMETE – VOLUMETRIC ROTARY PISTON WATER METER

1. Introduction to AMT VP Series Ammete Water Meter
The AMT VP Series is a volumetric water meter that uses a high-precision rotary piston mechanism, allowing direct measurement of the actual water volume passing through each cycle.

Unlike traditional mechanical water meters, the VP Series measures based on true volumetric displacement, delivering superior accuracy, especially at low flow rates.

The product is MID (Measuring Instruments Directive 2014/32/EU) certified – a strict European metrology standard, ensuring legal compliance for potable water billing applications.

2. Operating Principle of Volumetric Water Meter
The AMT VP Series operates based on the following mechanism:

• A precision rotary piston inside a sealed measuring chamber
• Each cycle corresponds to a fixed water volume
• Total flow is calculated by counting piston cycles

👉 As a result, measurement error is minimized, especially under low or unstable flow conditions.

3. Key Features of AMT VP Series Ammete

🔹 Ultra-High Accuracy (R160)
Achieves R160 accuracy class, significantly higher than conventional multi-jet meters, suitable for:

• Commercial systems
• High-end residential buildings
• High-precision metering systems

🔹 Measures Very Low Flow Rates
The piston sensor accurately detects:

• Minimum flow rates
• Water leakage in the system
• Abnormal consumption

🔹 Multi-Position Installation (ANY POSITION)
Can be installed in:

• Horizontal position
• Vertical position
• Inclined position

without affecting accuracy.

🔹 Volumetric Piston Technology

• Direct water volume measurement
• Independent of flow velocity
• Long-term stability

🔹 Integrated System Protection

• Inlet strainer prevents debris entry
• Backflow prevention valve
• Protects piston from mechanical jamming

🔹 Sealed Magnetic Drive

• No direct water contact
• Reduced mechanical wear
• Extended service life
