i2O System
Basic pressure management ‐ PRV
The i2O System. Benefits Variability = 0.5m 13 m Reduction Av P3 = Target P3 + Margin of safety +Variability 33% Reduction Av P3 = 20 + 0 + 0.5 (Assuming AZP = 40m) Av P3 = 20.5 m
i2O System ‐ PRV control components Controller • Measures pressures and flows with high accuracy • Continuous adjustment of i2O APV • GPRS and Bluetooth communication • Low power consumption – 5 year battery life • Robust, waterproof enclosure APV (Advanced Pilot Valve) • Accurate control over 32m range. • Variable speed of adjustment • Reliable • Low power ‐ 100s of adjustments per day P3 Sensor • Measures pressure with high accuracy • GPRS and Bluetooth communication • Low power consumption – 5 year battery life • Robust, waterproof enclosure
