  • Air usage data increases company profit - Case Study

    A large American container company required mass flow meters on their air compressor lines to help evaluate the efficiency of blow mold machines in their plant. The manufacturer melts PET chips and extrudes them through blow mold machines to produce plastic bottles for the beverage industry. Plant engineers need data on compressed air usage to help them reduce utility and production costs. Four ...

  • Soil Air Permeability: Threshold Gradient and Anisotropy

    In this study, a triaxial confinement chamber and mass flow meter were used to measure the air permeability of compacted clayey sand specimens. Specimens were extracted at different angles with respect to the vertical direction to measure the anisotropy. The soil was compacted at high water contents below the optimum.At lower gradients, deviations from Darcy´s law were observed. Threshold ...

  • Facility reduces process downtime – Case Study

    A facilities subcontractor for Boeing required meters to monitor the make-up air mass flow rate into a painting facility. The make-up fans ensure compliance with OSHA and Boeing air quality standards by reducing contamination and airborne particles that result from over-spray. The Boeing standard dictates a minimum airflow of 125 SFPM to the paint booths. Should the airflow drop below this ...

  • Thermal Mass Flow Meters Improve Efficiency in Wastewater Treatment Plants

    Every municipality throughout the country has a wastewater treatment plant to safely treat water that enters back into our environment. This doesn’t mean they are immune to problems. One of the biggest problems for US wastewater treatment plants is the aging infrastructure with an estimated 180 billion dollars needed to repair many wastewater plants. A close second is the energy needed to ...
