Thermal vs. laminar differential pressure mass flow measurement technology When choosing mass flow measurement technology, there are many important factors to consider, including: Accuracy Pressure and flow limits Repeatability Response speed Turndown ratio Gas or liquid compatibility Cost Two common types of mass flow measurement technology include laminar differential pressure and thermal. While thermal technology […]
Clamp-on flow meters and Alicat portable flow meters A key benefit of portable flow meters is their ability to measure flow without needing to be built into your process. Here we analyze two portable flow meter technologies: the commonly used ultrasonic clamp-on flow meter and the Alicat portable differential pressure-based mass flow meter. We will […]
Flow instruments for low-flow liquid applications There is a wide range of flow technologies available for measurement and control in low-flow liquid applications, from mass flow and differential pressure to velocity flow and positive displacement. Here we analyze some of the most popular low-flow liquid flow solutions and evaluate use cases of each. Skip ahead […]
Rotameters vs Alicat flow meters for bioprocessing Any bioprocess needs flow meters to feed bioreactors, drive filtration and chromatography, and monitor critical process parameters. Here we provide a comparison of the operating principles and key features of two flow meter technologies: rotameters and Alicat mass flow meters. We then provide recommended use cases for each […]
