This Swing Vane Anemometer helps you ensure the correct operation of air filters and thus helps maintain the standards you require for your cleanroom. It provides an accurate reading (in inches of water column) of pressure differentials across a filter.Fluid Requirements: Uses 0.826 sp. gr. (red, oil). Dec 21, 2018 · The Dwyer 480 Vaneometer anemometer with swing vane indicator measures air velocity from 25 to 400 fpm, and has a built-in spirit level vial to maintain horizontal plane for accurate readings.4.5/5(20).
Vane anemometers. One of the other forms of mechanical velocity anemometer is the vane anemometer. It may be described as a windmill or a propeller anemometer. Unlike the Robinson anemometer, whose axis of rotation is vertical, the vane anemometer must have its axis parallel to the direction of the wind and therefore horizontal. The MODEL 480 Vaneometer™ Swing Vane Anemometer is a durable, economically priced instrument specifically designed to simplify the measurement of low air velocities. It is accurate to ±5% of full scale to 100 FPM and ±10% from 100 FPM to the top of scale. It has a spirit level to ensure accurate readings and the large scales are easy to read and visible from both sides.
Air pressure measured by a tube anemometer can be used to calculate wind data. Laser anemometers use Doppler wave frequency information to determine wind speed and direction. Hot-wire anemometers measure how much wind cools heated wires. Differences Between a Wind Vane and an Anemometer. Different Types of Anemometers. The 480 Vaneometer Swing Vane Anemometer is a durable low-priced instrument specifically designed to simplify the measurement of low air velocities from 25 to 400 feet per minute. OSHA, EPA, and other safety ventilation requirements for spray booths and at fume, smoke, and dust exhaust hoods can now be quickly checked, even by untrained personnel.Price: $39.9.
