Application of Wireless Pressure Sensors in Water Management: Nexisense 100-1101 Enables Efficient Smart Water Monitoring

With the accelerated advancement of smart water management construction, wireless pressure sensors, thanks to their advantages of no wiring, low power consumption, and remote real-time transmission, are gradually replacing traditional wired solutions and becoming core equipment in scenarios such as urban water supply, wastewater treatment, and pipe network monitoring. This article focuses on exploring the technical characteristics, typical applications, and practical value of the Nexisense 100-1101 wireless pressure sensor in the water sector, providing reference for water industry practitioners.

Introduction: Traditional Pain Points in Water Monitoring and the Wireless Trend

Water management systems feature extensively interconnected pipe networks with numerous nodes, ranging from water sources to end users, involving a large number of pressure monitoring points such as pumping stations, valve chambers, pipe networks, and district metering. Traditional wired pressure sensors face issues including difficult wiring construction, high costs, frequent maintenance, and susceptibility to signal interference — problems that are particularly pronounced in underground pump rooms, remote water sources, and renovation projects of old communities.

In recent years, with the maturity of low-power wide-area network technologies such as NB-IoT and LoRaWAN, wireless pressure sensors have achieved true "install-and-use" capability. The Nexisense 100-1101 series is a typical representative of this trend: it features built-in large-capacity lithium batteries, mature wireless communication, and high protection ratings, enabling long-term stable operation in complex water environments and providing reliable technical support for pipe network digitization, leakage control, and operational optimization.

Core Technical Advantages: Reliable, Stable, Low Maintenance

The Nexisense 100-1101 wireless pressure sensor adopts imported diffused silicon sensing elements combined with digital compensation circuits, achieving high precision (typically ±0.5%FS) and high-stability measurement. The measuring range covers -100kPa to 6MPa, compatible with liquid and gas media, and matched with 304/316L stainless steel process connections, suitable for common water conditions such as clean water, sewage, and circulating water in water applications.

Energy consumption control is the lifeline of wireless devices. This product is equipped with a built-in 8000mAh high-performance lithium battery and, through intelligent sleep and adaptive sampling mechanisms, can support continuous operation for up to several years without external power supply or frequent battery replacement, truly achieving a "maintenance-free" level.

In terms of communication, it supports multiple mainstream protocols including NB-IoT, 4G, and LoRaWAN, with NB-IoT excelling in deep coverage and low power consumption — maintaining stable connections even in underground pipe corridors and under metal manhole covers. Data transmission uses CoAP or MQTT protocols, facilitating seamless integration with smart water platforms and enabling remote parameter configuration, firmware upgrades, and batch management.

The product is equipped with a local LCD/LED display screen, allowing on-site inspection personnel to quickly read current pressure values. The housing adopts 304 stainless steel or aluminum die-casting process, with an IP65 protection rating, supporting moisture-proof, dust-proof, lightning-proof, and anti-electromagnetic interference design. Operating temperature range: -20°C～+60°C, suitable for most water industry field environments.

Core Application Scenarios in the Water Sector

1. Urban Water Supply Pipe Network District Metering & Leakage Control
   In DMA (District Metered Area) management, wireless pressure sensors are installed at key nodes (such as after district valves, main pipes, district endpoints), collecting pressure data in real time. Cloud platform analysis of pressure trends and minimum night flow can effectively locate hidden leakage points and assist in precise leakage reduction.

2. Water Plant & Pumping Station Operation Monitoring
   Points including water plant inlet/outlet pressure, filter before/after differential pressure, dosing pump outlet pressure, etc., can all be equipped with wireless sensors. After real-time data upload, operation and maintenance personnel can view data via mobile phones or computers, avoiding the inefficiency and safety risks of traditional inspections.

3. Wastewater Treatment Process Pressure Monitoring
   Sensors can be deployed at aeration tanks, sludge return pumps, dewatering machine inlet/outlet, etc., to monitor pressure fluctuations, promptly detect blockages, pump failures or valve abnormalities, ensuring continuous and stable process operation.

4. Fire Protection Water System Remote Pressure Monitoring
   High-rise buildings and industrial park fire protection pipe networks require 24-hour pressure maintenance. Wireless pressure sensors installed at fire pump outlets and pipe network endpoints will immediately trigger system alarms if pressure falls below the set value, ensuring reliable fire water sources.

5. Secondary Water Supply (High-level Tank & Pipe Network Monitoring)
   Many residential secondary water supply systems have complex and concealed pipelines. The wireless solution requires no large-scale renovation and enables combined monitoring of tank levels and pipe network pressure, improving water supply stability.

   
   

Deep Integration with Smart Water Management Platforms

Nexisense 100-1101 supports standard protocol docking and can connect to existing SCADA, GIS, and smart water cloud platforms. After cloud processing of collected data, functions such as pressure heat maps, anomaly warnings, historical reports, etc., can be generated. Combined with AI algorithms, it can also achieve pressure anomaly prediction and pipe network health assessment, providing data support for refined water management.

In actual projects, many water companies have reduced pipe network leakage rates by 5%–15% through deploying such sensors, with significantly improved operation and maintenance efficiency and obvious overall economic benefits.

Future Trends: Wireless Monitoring Drives Digital Upgrading of Water Management

With the further popularization of 5G and edge computing, wireless pressure sensors will evolve toward higher precision, longer service life, and edge intelligence. In the future, we may see composite wireless nodes integrating multiple parameters such as flow rate and turbidity, or true zero-maintenance solutions achieved through solar self-powering.

For water companies, adopting mature wireless monitoring technology is no longer merely a nice-to-have, but a necessary means to reduce costs and increase efficiency, ensure water supply safety, and achieve high-quality development.

FAQ: Answers to Common User Questions

Is the signal stable for wireless pressure sensors in underground chambers?
NB-IoT is designed for deep coverage and performs well in most urban underground environments. In actual projects, signal coverage typically exceeds 90%. In weak signal areas, external antennas can be added or the LoRaWAN solution can be selected.

How many years can the battery life reach? What does it actually depend on?
With reasonable sampling intervals (e.g., collecting once every 15–60 minutes and uploading several times per day), it can support more than 3 years. Influencing factors include upload frequency, ambient temperature, and network quality, which can be flexibly optimized through the platform.

Can it connect to existing water SCADA systems?
Yes. It supports integration with mainstream SCADA and GIS systems through MQTT/CoAP protocols or platform data forwarding, achieving data interoperability.
