Application of Nexisense Pressure Sensors in Urban Water Supply Pipelines: Real-Time Monitoring to Ensure Water Supply Safety and Efficiency

Urban water supply systems are a core component of public infrastructure, relying on modern sensing and communication technologies to monitor pipeline pressure and flow in real time. Pressure sensors capture abnormal fluctuations to provide early warnings of pipe bursts or leaks, preventing water resource waste and supply interruptions. Nexisense pressure sensors are widely used in this field due to their reliable performance, supporting scientific management and cost optimization.

Definition and Function of Pressure Sensors

A pressure sensor is a device that converts medium pressure into a standard electrical signal. In urban water supply pipelines, it primarily monitors water pressure fluctuations to ensure stable system operation. Threshold parameters are set so that once the pressure exceeds the allowable range, an alarm is triggered, enabling maintenance personnel to respond quickly and prevent escalation of incidents.

Nexisense products are compatible with liquid media and support remote signal transmission, facilitating the digital transformation of pipeline networks.

Working Principle Analysis

Nexisense pressure sensors are based on diffused silicon or ceramic sensing element principles. Pipeline water pressure acts on an isolation diaphragm, causing deformation of the sensitive element and generating an electrical signal. After amplification and compensation by internal circuitry, current, voltage, or RS485 signals are output. These signals are connected to the monitoring center to enable remote data analysis and automatic regulation.

This principle provides fast response and is well suited to the dynamic environment of water supply systems.

Internal Structure Analysis

The housing is made of stainless steel, offering corrosion resistance and compatibility with water media. The core structure includes a sensitive diaphragm, a signal processing module, and a terminal box. The diaphragm comes into direct contact with the water flow, while the module performs linearization and temperature compensation.

With a high protection rating and multiple interface options, the sensor is easy to integrate into pipeline systems.

Key Advantages

High accuracy (0.1% FS to 1% FS), excellent stability, fast response, and strong impact resistance. These characteristics ensure reliable data in complex urban pipeline networks and reduce false alarms.

A wide measurement range (-100 kPa to 100 MPa) and multiple output options make integration with existing systems easy. Users can select accuracy levels based on budget to balance cost and performance.

Application Scenarios in Urban Water Supply Pipelines

Sensors are installed at valves, pump stations, and branch nodes to monitor changes in water supply pressure. Abnormally high pressure may indicate blockages, while low pressure often suggests leakage.

Combined with flow sensors, they form a pipeline health diagnostic system. Real-time data supports scientific dispatching, optimizes pressure distribution, reduces energy consumption, and lowers the risk of pipe bursts. In the renovation of aging pipeline networks, these sensors help detect hidden risks early and extend infrastructure service life.

Measurement Methods and Installation Standards

Measurement typically adopts a direct-contact, gauge pressure mode. A pressure shut-off valve is installed between the sensor and the medium to facilitate maintenance and prevent blockage.

The installation location should be a point with representative pressure, avoiding interference from elbows. Threaded connections ensure reliable sealing. Flexible power supply options are available, and outputs are connected to SCADA systems to enable threshold alarms.

Maintenance and Service Guidelines

Regularly inspect and clean the pressure tapping port to prevent blockage by sediment. Calibrate accuracy annually and verify threshold settings. In corrosive environments, promptly rinse the diaphragm.

Store in a dry, moisture-proof environment and protect against vibration during transport. Proper maintenance reduces failure rates and ensures long-term accuracy.

Technical Specifications Overview

Additional Optimization Recommendations

Implement multi-point distributed monitoring to create a pipeline pressure map. Integrate with GIS systems to visualize fault location. Wireless options support remote access for isolated pipeline sections.
