Inline Flow Meters for Data Center Cooling: A Complete Engineering Guide to Technology Selection, Sizing, and PUE Optimization
Data centers consumed an estimated 4.4 % of total U.S. electricity in 2024, with cooling infrastructure responsible for 30–50 % of that draw (LBNL 2024 U.S. Data Center Energy Usage Report — PDF). The global flow-meter market itself reached USD 11.44 billion in 2025 and is forecast to hit USD 12.14 billion in 2026 (Fortune […]
How to Install, Calibrate, and Read a Rotameter for Accurate Flow Measurement
A rotameter — also known as a variable area flow meter — is one of the most widely deployed flow measurement instruments in industrial history. First patented in 1908 by Karl Küppers in Germany, the rotameter has survived over a century of technological disruption precisely because its operating principle requires no external power, no electronics, […]
