The application of NB-IoT Wireless Smart Instruments in community direct drinking water system remote monitoring projects provides an efficient solution for ensuring safe water supply, stable pipeline operation, and intelligent management.

Direct drinking water, also known as healthy living water, refers to water that is free from contamination and deterioration, meets human physiological needs, contains beneficial mineral elements similar to those required by the human body, and has a mildly alkaline pH value. Long-term consumption of direct drinking water is beneficial to human health. Compared with ordinary drinking water, it has better clarity, improved taste, and lower economic costs, which has led to the rapid development of various direct drinking water projects.

Direct drinking water systems are now widely used in:

• Residential communities

• Schools

• Real estate developments

• Public facilities

• Office buildings

• Hospitals

In most direct drinking water systems, separate water supply networks are adopted to deliver purified drinking water directly to users. This means that municipal tap water is separated into domestic water and drinking water. A dedicated pipeline network is established, and advanced purification processes are applied to deeply treat tap water into high-quality drinking water. The purified water is then delivered to households through food-grade pipelines, achieving separate supply and distribution of drinking water and domestic water.

During the transportation of purified water through pipelines, maintaining proper water pressure is essential. Excessive pressure may cause pipeline damage or leakage, while insufficient pressure may prevent water from reaching users properly. At the same time, water quality must comply with national drinking water standards. Therefore, continuous monitoring of pipeline pressure and water quality is necessary.

Traditionally, most pressure sensors require personnel to check measurement values manually on-site, while water quality testing requires periodic inspections. This approach consumes significant manpower and resources and makes efficient management difficult.

By combining sensor technology with IoT communication technology, remote monitoring of pipeline pressure, water quality, and valve status can be achieved. Through PC software, mobile APPs, and cloud platforms, operators can dynamically monitor the entire water supply system, obtain real-time information about pipeline pressure and water quality, ensure pressure remains within the normal range, and guarantee safe and qualified drinking water delivery to end users.

Toprie NB-IoT Wireless Smart Instruments provide an effective solution for these challenges.

The NB-IoT Wireless Smart Instrument system consists of:

• Wireless pressure and temperature gauges

• Water leakage sensors

• Wireless level sensors

• Water quality monitoring instruments

After installation in the drinking water system, the instruments can continuously monitor parameters such as:

• Pressure

• TDS (Total Dissolved Solids) / water quality

• Liquid level

• Temperature

• Other environmental parameters

The collected data can be transmitted to IoT cloud platforms, including China Telecom IoT Platform, China Mobile OneNET, Huawei IoT Platform, TLINK, and other compatible platforms. Users can access real-time data through computers, mobile phones, or other terminals.

When abnormal conditions occur, the smart instruments can immediately send alarm notifications through multiple channels, including WeChat, SMS, phone calls, and email, allowing maintenance personnel to take timely action.

The instruments are powered by built-in lithium batteries and can operate continuously for more than five years, reducing maintenance costs and eliminating frequent battery replacement.

The NB-IoT Wireless Smart Instrument also supports historical data storage and breakpoint retransmission. If network communication is interrupted unexpectedly, the device automatically stores measurement data locally. After the network connection is restored, historical data will be uploaded to the IoT cloud platform immediately, preventing data loss. The device also supports USB data export, providing dual data storage protection for improved reliability and security.

Designed for demanding industrial environments, the NB-IoT Wireless Smart Instrument can withstand harsh conditions such as:

• Moisture

• Water exposure

• Dust

• Immersion

• Explosion-risk environments

The pressure sensor features excellent temperature stability and long-term stability. With a 200% FS overload pressure design and a corrosion-resistant, impact-resistant 316L stainless steel isolation diaphragm, it can directly measure most types of media.

After Toprie NB-IoT Wireless Smart Instruments are installed in community direct drinking water pipelines, operators can not only view pressure and water quality data directly on the instrument display but also remotely monitor and configure connected devices through the IoT cloud platform, WeChat public accounts, and WeChat mini programs.

Once monitored data exceeds preset limits, the system automatically triggers alarms through configured methods, including:

• WeChat notifications

• SMS

• Voice calls

• Email

This enables operators to continuously monitor pipeline pressure and water quality conditions, preventing problems such as excessive or insufficient pressure and non-compliant water quality. The solution reduces labor and maintenance costs while providing reliable protection for safe, healthy, and qualified direct drinking water supply.
