R160 water meters are designed for high accuracy across a wide flow range. However, many R160 water meters lose accuracy over time due to design choices that prioritize initial sensitivity. To improve the small flow sensitivity (Q1), manufacturers often use an extremely thin transmission shaft inside the meter mechanism.

This thin shaft reduces friction but wears out faster, especially when water contains impurities or particles. As the shaft wears, the clearance between the shaft and its bearing increases, causing wobbling or misalignment. This leads to uneven rotor rotation and significant measurement errors.

As a result, many R160 water meters can no longer maintain the R160 accuracy class and degrade to below R100 after 1–2 years, failing long-term durability and accuracy standards.

To avoid this issue, choose durable R160 water meters with robust transmission shafts that have passed rigorous European MID certification tests.
