VELOCICALC

®

Rotating Vane Anemometer

Model 5725

The VELOCICALC 5725 is a high performance, yet simple to use,

rotating vane anemometer. High accuracy and reliability make

the V

ELOCICALC 5725 the professional’s ideal tool for measuring

unevenly distributed or fluctuating flows through heating and

cooling coils, diffusers, grilles, and filters.

It accurately measures air velocity and temperature, calculates

flow rate, performs averaging, and can determine minimum

and maximum readings. Using sweep mode you can quickly

provide one averaged reading of velocity or volume over a large

measurement area. The large vane head automatically

averages velocity and volume readings. The V

ELOCICALC 5725

includes variable time constant, sampling and statistics

functions and data logging capability.

Aircone Flow Hoods

Aircone Flow Hoods are a fast and accurate method of

maximizing the usefulness of your 4-inch (100-mm) rotating

vane anemometers. For a modest investment, you can

enhance the capability of your rotating vane, turning it into an

air volume flow balancing tool.

Features and Benefits



Rectangular and circular cones available



Measures volumetric flow at grilles, diffusers, and linears



Reads air volume quickly and accurately



Excellent choice for small grilles

TSI Aircone Flow Kit (p/n 801749) includes one each:

Rectangular 11.2 in. x 9.2 in. (285 mm x 235 mm)
Round 7.1 in. (180 mm) diameter
