      Nel Hydrogen switches to mass flow meters for more accurate flow verification on high-tech PEM electrolysers

      Nel Hydrogen switches to mass flow meters for more accurate flow verification on high-tech PEM electrolysers Hydrogen, the most abundant, energy-dense element in our universe, is a highly desirable energy source. Unfortunately, most hydrogen production utilizes natural gas and releases harmful greenhouse gases into the atmosphere. In an effort to improve the sustainability of hydrogen, […]

      Understanding Alicat calibration and accuracy specifications

      Understanding Alicat calibration and accuracy specifications Each device that goes through an Alicat calibration comes with a NIST-traceable Certificate of Calibration. This guarantees that the device’s calibration can be traced back to primary SI standards such as mass and pressure. As a result, an Alicat device will output mass flow rates that fall within the […]

      Validating, verifying, and calibrating flows

      Validating, verifying, and calibrating flows Validation, verification, and calibration all share the common goal of ensuring a process is working as intended. Here, we discuss these three interrelated but distinct processes and detail how to go about validating, verifying, or calibrating your system. At a basic level, the three terms may be defined as follows: […]
