AIRFLOW in physics, laminar flow is the movement of fluids (liquids or gases) in which the fluid travels smoothly or in regular paths, in contrast to turbulent flow, in which the fluid undergoes irregular fluctuations and mixing. Velocity of flow of liquids and gases is determined with pitot tubes and flow probes by dynamic pressure. Simple physical principles are employed. Vane anemometers already record the slightest airflow.
Precision ball bearings and light metals provide for low starting values and high dynamics of the rotors. The blades of LAMBRECHT's anemometers are very carefully and evenly counterbalanced against the rotation level. The number of revolutions is therefore proportional to fluid velocity in axial direction. Hence, the result is very reliable.
Flow measurement takes place wherever movement of liquid or gaseous media influences processes and system securities, e.g. in underground mining, in tunnels, pipelines, or chimneys, as well as in workshops and drying plants, air conditioning, and clean room technology.
