● 2026-08-31 ● - ● Leave me a message

Water utility companies, municipal project contractors and water meter importers need to carefully evaluate technical parameters before purchasing volumetric water meters. Improper meter selection can lead to inaccurate billing, high pressure loss and unstable operation. YOUNIO R200 volumetric water meter delivers reliable metering for residential water supply projects. This article lists the key technical specifications that buyers must verify for procurement and tender review.

1. Operating Working Conditions

Water temperature: ≤30℃ (T30 temperature class, cold water application only)

Water pressure: ≤1MPa; Nominal pressure PN1.6MPa /16bar

Pressure loss: ΔP ≤0.1MPa for Class C; ΔP ≤0.063MPa for R160 version

Installation orientation: Supports horizontal or vertical mounting (H/V orientation limitation)

2. Metering Accuracy Standard

The R200 volumetric water meter follows Class 2 accuracy with clear error tolerance in different flow zones:

Low flow zone (Q1 inclusive to Q2 exclusive): Maximum permissible error ±5%

High flow zone (Q2 inclusive to Q4 exclusive): Maximum permissible error ±2% This stable accuracy helps reduce water leakage detection errors and improves billing fairness for water utilities.
