Process anemometer

ThermoAir6/64 with omnidirectional sensor (top) and unidirectional sensor (bottom).

Voltage output 0 ... 1.0 V or current output 4 ... 20 mA available.

The parameter air-flow velocity is related to the unlimited flow; in the case we measure the volume flow in a closed pipe we can measure the volumetric flow rate ΔV/Δt or the mass flow rate Δm/Δt if the cross-section of the pipe is known.
