2 Applications That Triggered The Rise Of Coriolis Flow Measurement
Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.
LATEST INSIGHTS ON WASTEWATER

As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.
-
The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.
-
Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.
-
While many scientific and technical reports show that floods are becoming larger and more common, reports underestimate how their frequency is changing. Flood sizes get the spotlight, but governments and experts need to also consider their frequency to address implications overlooked by traditional management methods.
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
