Accurate Metering for Residential Water Systems

This Single Jet Wet Type Water Meter is designed for dependable measurement in residential and light commercial applications where accuracy, readability, and durability are essential. Built on a velocity measuring principle, it delivers stable performance across daily consumption ranges while remaining sensitive to small flows. The liquid-filled dial improves reading visibility and helps reduce fogging, allowing the register to stay clear in humid or demanding service conditions. With its compact DN15 size and threaded BSP connection, the meter is easy to integrate into standard horizontal pipeline installations.

Durable Structure for Harsh Installation Environments

Engineered for long-term reliability, this meter features IP68 protection and a hermetically sealed register, helping shield internal components from water ingress, dust, and condensation. Its anti-magnetic protection supports more stable measurement performance in environments where external interference may affect ordinary meters. Manufactured in compliance with ISO 4064, the meter is built to meet recognized standards for quality and performance. The Class B (R160) accuracy level also makes it highly effective for low-flow detection, supporting fairer billing and more precise water usage monitoring.

Key Features & Advantages:

  • High low-flow sensitivity: With R160 accuracy and a low starting flow, the meter can capture small consumption more effectively, improving measurement confidence.
  • Reliable sealed design: The IP68 housing and sealed register help maintain long service life in wet meter boxes, underground chambers, and outdoor installations.
  • Smart-readiness flexibility: Optional pulse output / AMR ready capability makes future remote reading integration easier, giving this meter added value for both conventional and upgraded metering systems.
