Piston prover technology for measuring gas flow rates have evolved over the last twenty years. The latest high-speed clearance piston prover featuring a horizontal piston design, as has been introduced in the Bios/DryCal ML OneTM, can measure corrosive gases and automatically apply compressibility factor correction for non-ideal gases.
The horizontal design, while more complex than previous vertical tube designs, allows for faster measurement speed with reduced dynamic pressure changes that can introduce measurement uncertainty. Additionally, this technology is engineered from corrosive resistant materials allowing many corrosive gases to be measured.
By engineering a piston prover with corrosive resistant material, non-inert gases can now be measured where previously measurement could only be done with great difficulty or with less accurate measurement technologies.
Ed Morrell, Director of Engineering, will detail this technology as he presents this topic at the Measurement Science Conference for 2013 held in Anaheim, California at the Disney Convention Center March 18 through the 22nd. Mesa Laboratories will be exhibiting under Bios International at booth 61. Please feel free to swing by and ask us as many questions as you would like. We will also be displaying our ML Series gas flow calibrators and we look forward to seeing our professional partners at MSC!
