6.4 Measurement accuracy
Each flowmeter is standard wet calibrated under reference conditions by direct volume
comparison. The performance of the flowmeter is defined and documented in an individual water
meter calibration certificate.
Reference conditions
• Medium: water
• Temperature: +10...30°C / +50...86°F
• Pressure: 1 bar / 14.5 psi
• Inlet section: ≥ 3 DN
• Outlet section: ≥ 1 DN
• Electrical conductivity: ≥ 300 μS/cm
