The Sauermann Si-K85 (28112) Square Air Flow Cone is an essential instrument for direct measurement of air flow within ventilation and air conditioning systems. This instrument can be used with the 100 mm diameter vane anemometers from class 110, 210, and 310 portable instruments, such as the LV 110, LV 130, VT 210, MP 210, or AMI 310 anemometer.

Measurement Principle

The Si-K25 cone has a built-in honeycomb air flow straightener that reduces turbulence and enables more accurate air flow measurements. This instrument is designed for accurate measurements of both straight and turbulent air flow on all major ventilation grilles and plate outlets, including multi-directional ones. This cone features a compact unibody design with no parts to assemble, making it easy to handle, especially in tight spaces.

Integrated Flow Straightener

To ensure even more reliable measurements, the Si-K25 cone incorporates a honeycomb structure that reduces turbulence and produces a laminar flow suitable for vane anemometers on all types of vents. Operation of the instrument is simple and involves placement of the user's vane probe on the cone. Once adjusted, the user can place the cone on the air vent and obtain accurate measurements via their anemometer.
