Fecheimer Probe

How can you accurately determine the airflows and velocities in moderately turbulent flow?

  • 304 Stainless Steel Construction

  • Type "K" Thermocouple

  • Measures static pressure, differential pressure and yaw angle

STORM’s Fecheimer probe is ideal for testing in locations with turbulent airflow such as test planes close to fans or internal bracing, bends in the duct work and more. The Fecheimer Probe is a three-hole probe with one impact hole and two static holes. This allows the probe to be null balanced to determine the yaw angle of flow and to correct the velocity head. They are manufactured in 2ft intervals from 6ft to 20ft, however custom sizes are available.

Primary Uses:

  • Measuring and balancing secondary airflow to wind box and burners
  • Measuring primary airflow to each pulverizer
  • Calibrating airflow measuring devices (airfoils, venturis, flow nozzles, etc)
  • Fan testing
