Volume flow, duct

9.4.2
Use this application to measure the volume flow in a ventilation system duct.
There are various options for this, which differ mainly in terms of the measuring
range and the required probes:
• Thermal flow velocity probes for low flow velocities
• 16 mm vane probe for medium flow velocities
• Pitot tube for measurements at high velocities and in heavily contaminated
flows with a high particle content
