Air Velocity

Keeping air flows at the desired level is crucial in many applications, especially in air conditioning, heating, and ventilating.

Air velocity (distance travelled per unit of time) is usually expressed in meters per second (m/s) or feet per minute (f.p.m.). Air volume can be determined by multiplying air velocity by the cross section area of a duct. This is usually measured in cubic meters per hour (m3/h) or cubic feet per minute (c.f.m.).

Sigma offers a variety of digital indicators and controlers to interface with the available sensors.
