Description

The HOBO CDI-5200 / CDI-5400 Compressed Air Flow Meters adds the ability for the user to measure compressed air. These measures flow by maintaining one probe warmer than the other. It calculates the mass velocity from the amount of heat required, and then calculates the flow on the basis of pipe area. Two sizes are available to fit 1 inch steel pipes and 2 inch steel pipes.
