Overview
The digital water flow meter provided by Viewshine introduces an advanced residential ultrasonic water meter that integrates state-of-the-art technology. It utilizes a non-contact measurement principle by transmitting and receiving ultrasonic signals to calculate water flow. This measurement method ensures high precision and a wide measurement range. In contrast to conventional mechanical meters, the absence of mechanical transmission mechanisms minimizes pressure loss, resulting in an extended lifespan and improved reliability. By employing ultrasonic technology, the meter can accurately detect flow rates as low as 2L/h, making it an ideal solution for addressing concerns related to non-revenue water.
Main Features
1. Extensive Dynamic Range Options: The meter is available in R400 and R250 variants, providing a broad range of measurement capabilities.
2. U0/D0 Compatibility: The water meter seamlessly integrates with U0/D0 functionality, enabling accurate metering without the need for extended pipes.
3. Detection of Lowest Flow Rates: The meter is capable of accurately detecting flow rates as low as 2L/h, ensuring precise measurement even for minimal water usage scenarios.
4. Unaffected by Impurities and Magnetic Fields: The meter remains impervious to the impact of impurities or magnetic fields present in the water supply, guaranteeing accurate measurements regardless of water quality or external influences.
5. Extended Lifespan: Designed for long-term use, the meter has a projected lifespan of 12 years or more, minimizing the need for frequent replacements and enhancing overall reliability.
6. Versatile Installation: The meter offers flexible installation options, accommodating both vertical and horizontal orientations to suit various plumbing configurations and providing ease of installation.
7. Clear LCD Display: Equipped with an LCD display, the meter presents information in a clear and easily readable manner. Users can effortlessly monitor real-time water usage data and access meter parameters for efficient management.
8. Robust IP68 Protection: With an IP68 protection rating, the meter demonstrates exceptional resistance to dust and environmental factors. This robust protection ensures reliable performance, even in challenging conditions, ensuring accurate measurements and prolonged functionality.
