Director of Water Supplies Roger Wong on Thursday said sensors will be installed by 2027 to monitor ... But he said there have been a few water pipe bursts in the district in the past few years ...

The APV DW+ pump’s pulsation-free, low-shear design protects downstream equipment by reducing vibration, noise and pressure surges. In so doing, it maximizes operational efficiency, reduces downtime ...

A micro-displacement sensing head based on two aligned cleaved fibers inserted into an optical fiber ring and interrogated by an optical time-domain reflectometry is presented. The sensor ...

While displacement has almost doubled globally over the last decade, the rate of increase slowed in the second half of 2024. By the end of April 2025, UNHCR estimates that the global number of ...

Abstract: We report results on the response of a family of displacement sensors, which are based on the magnetostrictive delay line (MDL) technique, using current conductors orthogonal to the MDL.

The system supports both autonomous and manual control via a Wi-Fi interface and includes onboard sensing, communication, and navigation capabilities. The project integrates an STM32 microcontroller ...

Using water to displace carbon dioxide adsorbed in coal can prevent coal and gas outbursts. However, the mechanism of continuous water injection replacing adsorbed gases in coal has not been well ...
