While horizontal installation with the display facing upward provides optimal accuracy and ease of reading, most small diameter water meters can be installed in vertical or other orientations. However, installation position may slightly affect accuracy at very low flow rates. Always consult the specific product manual for orientation restrictions and any required accuracy adjustments for non-horizontal installations.

Our meters meet Class 2 accuracy standards, providing ±5% accuracy in the low flow zone (Q1 ≤ Q < Q2) and ±2% accuracy in the high flow zone (Q2 ≤ Q ≤ Q4) at water temperatures below 30°C. Multi-jet designs excel at low-flow measurement, maintaining accuracy down to 0.015 m³/h. This ensures fair billing even for minimal consumption scenarios like overnight usage or small fixture operation.
06

Yes, all our water meters comply with NSF/ANSI 61 standards for drinking water system components. Wetted materials use lead free brass with less than 0.25% lead content, meeting Safe Drinking Water Act requirements. We provide full certification documentation and material compliance certificates for customs clearance and regulatory approval in international markets.

Meter sizing depends on expected flow rates rather than pipe diameter alone. Calculate your average and peak flow demands, then select a meter where normal operation falls within the optimal measurement range (Q2 to Q3 zone). Generally, meters should not operate continuously above 70% of maximum flow (Q4) to ensure longevity. Our technical team can assist with sizing calculations based on your specific application parameters, occupancy, and fixture counts.
