F-5400 Series Thermal Mass Flow Meter

         ONICON’s F-5000 Series Thermal Mass Flow Meters provide accurate mass flow measurement of natural
gas, compressed air and other industrial gases. The proprietary sensor design measures mass flow directly and does not require additional pressure or temperature compensation to deliver accurate flow rate and total data.
          The F-5400 is available as an inline or an insertion style meter without a LCD display. This version of the meter is provided with a 4-20 mA analog output and pulse output.

APPLICATIONS

Accurate sub-metering of natural gas & propane for:
        •Tenant space usage
        •Boiler efficiency
        •Campus monitoring
Also ideal for monitoring:
       •Compressed Air
       •Medical gases
       •Other industrial gases
