Overview

 

The small water meter is an advanced residential ultrasonic water meter manufactured by Viewshine. It employs cutting-edge technology to measure water flow by utilizing non-contact ultrasonic signals. This measurement method ensures high accuracy and a wide measurement range. With the absence of mechanical transmission mechanisms, the water meter minimizes pressure loss, leading to a longer lifespan and enhanced reliability. Leveraging ultrasonic technology, it can detect the lowest flow rate of 2L/h, providing customers with an optimal solution for non-revenue water management.

 

Main Features

 

1. Expanded Dynamic Range: With R400/R250 options, the water meter covers a wider dynamic range, allowing accurate measurement across various flow rates.

2. U0/D0 Compatibility: The water meter seamlessly integrates U0/D0 functionality, ensuring precise metering without the need for additional components.

3. Lowest Flow Rate Detection: Capable of detecting flow rates as low as 2L/h, enabling accurate measurement even for minimal water usage.

4. Impurity and Magnetic Field Resistance: The water meter remains unaffected by impurities or magnetic fields, guaranteeing reliable measurements regardless of water quality or external factors.

5. Extended Lifespan: Designed for long-term use, the water meter boasts a lifespan of 12+ years, reducing the frequency of replacements and enhancing overall reliability.

6. Versatile Installation: The water meter offers both vertical and horizontal installation options, accommodating diverse plumbing configurations.

7. LCD Display: Equipped with an LCD display, the water meter presents clear and easily readable information, enabling real-time monitoring of water usage.

8. IP68 Protection: Featuring an IP68 protection rating, the water meter is highly resistant to dust and environmental factors, ensuring reliable performance in challenging conditions.

 

Main Functions

 

1. Accurate Metering: Precise and reliable measurement.

2. Comprehensive Data Recording: Capturing essential data.

3. Convenient Local Optical Port: Easy access to meter parameters and readings.
