Recently, I received a particularly heartwarming message: the Wutong Water Management Office has received a banner! The banner reads: “Diligent and Responsible, Thoughtful Reminders, Reducing Losses, Warming Hearts.” What kind of story lies behind this mutual effort? Let’s take a look together~ Smart water meters send alerts at night, making hidden leaks impossible to hide. … Read more
Introduction: The Development of Smart Water Meters and the Importance of Pressure Sensing In modern cities, with the growth of population and the acceleration of urbanization, the scale of water supply systems is becoming increasingly large, and the distribution of pipelines is complex. Traditional management methods face issues such as data fragmentation, delayed responses, and … Read more
Is Propylene (C₃H₆) Leak Always Hard to Detect? ‘Olfaction’ Upgrade Plan for Old Petrochemical Plants 01 Why Are Trace Propylene (C₃H₆) Leaks Always Missed? In an ethylene plant area, an operator noticed a slight leak at the seal of a propylene compressor, but the handheld detector showed “0ppm”. It only alarmed when the concentration rose … Read more
