The urban water supply system needs to rely on modern computer communication technology and sensing technology to monitor the pressure and flow information of water pipelines and urban water supply pipelines; Timely detection of pipeline faults, improvement of maintenance efficiency, reduction of losses, guarantee of water supply and delivery quality, achieve scientific warning, reduce costs, and improve efficiency. Install pressure sensors and other equipment at positions such as valves in urban water supply pipelines. The pressure sensors will set certain range parameters. Once the water pressure increases or decreases, maintenance personnel can promptly handle it to avoid accidents.

The shell of the pressure sensor is made of stainless steel material, which can measure liquids or gases compatible with the contact material. The range of the pressure sensor is between -100kPa to 0-100MPa, and the range can be set according to specific circumstances. The output signals of pressure sensors come in various forms such as current, voltage, and RS485, and there are also multiple forms of power supply voltage to choose from. The accuracy level is one of the most important parameters for pressure sensors, divided into 0.1% FS, 0.25% FS, 0.5% FS, and 1% FS. The accuracy level has a significant impact on the price and can be purchased according to specific budgets. Pressure sensors have the characteristics of high accuracy, good stability, fast response speed, and impact resistance, which meet the application in urban water supply pipeline systems. When installing pressure sensors, a pressure cut-off valve should be installed between the pressure sensor and the medium to facilitate maintenance and prevent blockage of the pressure tap from affecting measurement accuracy.
