Mass Flow Online B.V. articles
Measuring gas flow shouldn`t be complicated. That`s why we`ve developed the FLEXI-FLOW™ Compact series. A range of smart thermal mass flow meters designed to make your work easier, faster, and more accurate. Six models are now available in our web shop with shipment within 2 business days when in stock. Whether you`re running experiments in a university lab, developing fuel cells, or managing biotech processes, these meters deliver the flexibility and precision you need.
As artificial intelligence workloads continue to grow, high-performance chips such as the NVIDIA H100 and Blackwell architectures are pushing thermal limits with a thermal design power (TDP) of 700W or more. Effective cooling has become one of the most critical design factors for engineers in data center infrastructure and high-performance computing (HPC) systems.
What is an inline thermal mass flow sensor for gases and how does it work?
A thermal flow sensor uses the thermal properties of gases to measure their mass flow rate. To this end, heat is introduced into the flowing gas, and the (temperature) sensor measures how much heat is absorbed by the gas.
A traditional way of accurately measuring low gas flow rates is to use a mass flow meter with the
The ranges of thermal mass flow meters for gases are specified in such units as ln/min, sccm or m3n/h.
These units look like volumetric units, but in truth they are expressions of Mass Flow. What is the story behind this?
The accuracy (really inaccuracy) of mass flow instruments is specified in one of two ways, either accuracy as a percentage of full scale (% FS), or accuracy as a percentage of reading (% RD).
Thermal mass flow sensor for gases - inline principle
A thermal flow sensor uses the thermal properties of gases to measure their mass flow rate. To this end, heat is introduced into the flowing gas, and the (temperature) sensor measures how much heat is absorbed by the gas.
What is accuracy of a mass flow meter, what is repeatability of a mass flow meter, and what difference does the difference make?
Flow measurement is used to accumulate a fixed volume of fluid and count the number of times the volume is filled to measure the flowrate. Vortex meters are The Karman Vortex Flow principle is based on a law that was theoretically proven by Theodore von Karman in 1912. He stated that there is a proportional relation between the flow velocity of a fluid and the vortex generation frequency. Thus measuring flow is made possible through detecting the number or pulse of votices that are created wh
In recent years, a lot of research has been done into if Hydrogen (H2) could be a successor to fossil fuel and if it could be stored for generating electricity. With the new European green deal made by the European Commission for making Europe climate neutral in 2050, here will be more investment made in Hydrogen research to reach that target.
World-wide 1.5 million babies are born every week, over the last hundred years the human population has grown from fewer than two billion to over seven-and-a-half billion people. Aside from this people live longer due to better nutrition and healthcare and the average age of populations worl-wide is increasing. This means our planet has to feed over four times as many mouths as it had to a century ago and the world population is still growing.
