  • Digital Mass Flow Meter

    Digital Mass Flow Meter

    The Digital Mass Flow Meter accurately measures and displays mass flow rate, volumetric flow rate, gas temperature, atmospheric pressure and gas pressure, for both Air and Oxygen. Unlike most flowmeters, the Digital Mass Flow Meter has a touch screen interface, offering immediate customization in seconds.

  • Regulated Proportional Valve

    Regulated Proportional Valve

    This valve dynamically compensates for varying inlet pressures, while still maintaining consistent output flow characteristics. Effective in applications with either fluctuating or oscillating control pressures, the Pressure Compensating Proportional Valve can maintain flow rates with input pressures reaching 250 PSIG.
