  • Gas Flow Systems for Medical Devices
    Gas flow systems serve myriad purposes around the world. They are used to calibrate gas chromatographs (GC) in laboratory and analytical facilities and have been widely employed in the mixing, blending, and delivery of appropriate medical gas mixtures. Ground-breaking clinical research
  • 5 Best Practices for Calibrating Your Flow Meter
    A flow meter is a special device that measures the amount of gas or quantity of liquid or its flow rate moving through the pipe. Too little or too much gas or liquid flowing through the pipe may result in the malfunctioning of the machine
  • The Challenges of Measuring Flare Gas
    for this associated gas from day 1. This of course requires a flow meter calibrated to measure the flow rate of the flare gas. Virtually all current flow measurement technology requires a known composition for calibration. This presents a "chicken or egg" problem, since the composition may not be known
  • An Engineer's Guide to Selecting a Flow Restrictor
    A flow restrictor is any device that restricts or limits the flow of a fluid --generally a liquid or a gas. Such devices may also be referred to as flow limiters. Calibrated orifices are one example of flow restrictors. They are used in systems we encounter daily. For example, they control how fast
  • Adding Relative Humidity to Trace Concentration Gas Standards In a Permeation System (.pdf)
    Gas sensor sensitivity levels have increased in equipment where atmospheric conditions, such as relative humidity, directly affect test results. Calibrating for changes in relative humidity in trace level gas concentrations has generated the need for effectively adding relative humidity
  • LDE/LME Series - superior immunity to dust
    In this application note LDE/LME differential pressure sensors from First Sensor are experimentally compared to other sensors which use the same (thermal-anemometer-based, non-membrane) sensing principle, where differential pressure is inferred from a gas flow through the sensor. With dust
  • LDE/LME Series - superior immunity to humidity
    In this application note LDE/LME differential pressure sensors from First Sensor are experimentally compared to other sensors which use the same (thermal-anemometer-based, non-membrane) sensing principle, where differential pressure is inferred from a gas flow through the sensor. In high-humidity
  • Bringing Energy Efficiency and Cost Savings to Veteran's Facilities
    cost saving in energy over the long haul. What kind of data do facilities managers need to make these critical energy saving decisions?. The Best Place To Start-Ask the Right Questions. A great place to start is by getting accurate "flow energy" measurements of the methane/natural gas, water
