雅安DN15-DN20 Ultrasonic Cold Water Meter

Key Features: 1. Ultra-low power consumption with a built-in lithium battery offering over 8 years of continuous operation. 2. Wide flow range ratio, reaching up to 400:1 for maximum flexibility. 3. Extremely low start-up flow rate, enabling "drip irrigation-style" metering. 4. Supports both forward and reverse metering modes. 5. Equipped with an external SIM card slot for easy SIM replacement and installation. 6. Features advanced self-protection mechanisms to effectively safeguard the valve; the valve body delivers robust performance, ensuring safe valve control even under high-flow conditions. 7. Rapid measurement capability—up to 4 readings per second. 8. Can be installed either horizontally or vertically. 9. Self-diagnostic functions include: flow sensor failure alerts, over-range measurement warnings, and low-battery voltage notifications.
