Multi Jet Non-valve Smart Water Meter

Robust Mechanical Design

The ZYLXSG-B-1 is based on a multi-jet design, which channels water through multiple inlets to drive the impeller. This method reduces the effect of turbulence, ensures stability in measurement, and maintains sensitivity even to low water flow. Unlike traditional valve-controlled meters, this model operates entirely on water flow without an internal valve, delivering low pressure loss and an extended service life. By eliminating the need for an external power supply, the meter is highly suitable for residential and rural applications where consistent and long-term operation is critical.

Intelligent Features with IoT Integration

Although fundamentally a mechanical water meter, the ZYLXSG-B-1 incorporates a variety of smart features that align with the growing needs of smart city infrastructure and data-driven utilities. Its core functions include:

• Real-time flow metering supported by a Hall counter system for precise measurements.

• Long-term data storage capability hourly records for 90 days, daily records for 180 days, and monthly records for one year.

• Automatic daily reporting with details such as cumulative consumption, battery status, and signal strength.

• Multiple communication technologies, including NB-IoT, GPRS, LoRaWAN, and RS485, offering flexibility across different network environments.

• LED indicators and a digital display that show consumption data, device ID, communication errors, battery level, and other operational states.

• Low power consumption design enabling up to six years of battery life, which significantly reduces maintenance costs.

Technical Performance and Standards

The water meter complies with international standards GB/T 778.1~5-2018 (equivalent to ISO 4064), ensuring reliable measurement characteristics, installation requirements, and testing procedures. Additionally, JJG 162-2019 verification regulations specify that the device maintains a maximum error margin of ±2% at nominal flow rates and ±5% at minimum flow rates.

The ZYLXSG-B-1 is available in several diameters DN15, DN20, and DN25 with corresponding common flow rates of 2.5 m³/h, 4 m³/h, and 6.3 m³/h. With a high range ratio (Q3/Q1 = 80), the device guarantees wide-range measurement accuracy. Its design also supports peak working pressures of 1.6 MPa and provides IP65 protection grade against dust and water, making it durable in a variety of environmental conditions.

Screen and User Interface

The smart water meter is equipped with a low-power digital display that continuously shows current readings, remaining battery power, and network status. Users can manually trigger screen changes or reporting events via button presses or magnetic triggers. The screen design supports multiple pages, including cumulative flow, device ID, communication error codes, and LoRaWAN-specific parameters such as DevAddr and RSSI/SNR. This makes the interface intuitive and user-friendly for both end-users and service technicians.

Installation Guidelines and Reliability

To ensure long-term accuracy and performance, Zhongyi Smart provides comprehensive installation guidelines. The water meter should not be installed in sealed environments where wireless communication signals could be obstructed. It must also be protected from direct sunlight, freezing, and flooding. Before installation, pipelines should be cleaned to remove debris that could damage the impeller or sensors.

Additional recommendations include installing bleeder valves to prevent air from entering the system, ensuring proper alignment of inlet and outlet connections, and minimizing elbows or valves in the pipeline above the meter. These practices help maintain measurement accuracy and extend the device’s lifespan.

Common Problems and Solutions

Like all connected devices, smart water meters may face connectivity or operational issues. The manual outlines common scenarios such as NB-IoT or LoRaWAN connection failures, incorrect installation direction, or leaks caused by missing seals. For each problem, specific troubleshooting steps are provided, enabling users or technicians to quickly diagnose and resolve issues without disrupting service.

After-sales Service and Warranty

The ZYLXSG-B-1 comes with a one-year warranty, with options to extend coverage for up to nine years at additional cost. The warranty excludes damages caused by tampering, exposure to extreme conditions, improper installation, or use of the wrong product model. Zhongyi Smart offers comprehensive after-sales service through multiple communication channels, including email, WeChat, WhatsApp, and Skype, ensuring that customers worldwide receive prompt and reliable support.
