      Make an anemometer. Cup anemometers are relatively easy to make and are often used as an elementary school science project. This allows children to get an opportunity to learn about measuring wind speed by making their own device. To make an anemometer, you will need plastic cups, straws, a pencil, tape, and a push pin. Position the straws in the shape of a cross and tape the middle. 68%(22). • Install the anemometer in a location where wind flow is unob-structed by trees and nearby buildings. • For the most accurate readings, the anemometer should be mount-ed at least 4 feet ( m) above the roof line. • You may do this by mounting the anemometer on a television antenna mast, wooden post, or File Size: 1MB.

It was one of the methods Wurts spent a lot of time analyzing. "My first attempts at this gave me readings that I knew were off by 3 degrees to 5 degrees," he said. "I was surprised because this was such a common method for taking pipe temperatures.

    An anemometer is an instrument used to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind. To determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow. For example, a 20 mm elbow offers the same resistance to flow as a 20 mm pipe m long. Figure shows the equivalent pipe lengths for the fittings in the example in figure (g) Effective pipe length. The effective pipe length is the sum of the measured pipe length (d) and the equivalent pipe lengths for fittings (e) and draw-offs (f).File Size: KB.

METHOD FACTORS FOR ANEMOMETER MEASUREMENT AT PIPE OUTLETS By F. Garcia1 and J. Cervik* ABSTRACT Gob holes are routinely used by the mining industry to vent methane from gobs and to prevent it from entering the mine ventilation system.

In some cases, flows from gob holes are measured by centering an anemom-File Size: 1MB. Additional Physical Format: Online version: Garcia, F. (Fred).

These measurements are erroneous and tend to be high by as much as 30 pct. The Bureau of Mines determined method factors (correction factors) for anemometer measurements taken in this manner.

The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in first known description of an anemometer was given by Leon Battista Alberti in Get this from a library.

Methods factors for anemometer readings at tubing inlets. [Robert A Haney; Thomas C Hlavsa; United States. Mining Enforcement and Safety Administration.] -- Describes how accurate air velocity measurements have been obtained by applying a methods factor to vane anemometer readings at the inlet of an exhaust tubing installation.

An anemometer is an instrument used to measure the speed or velocity of air (gases) either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind.

To determine the air velocity, anemometers detect change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow. Air Quantity Measurement 2 Vane anemometers, smoke tubes and a Kurtz hot wire anemometer will be used to make veloc-ity measurements at the previously designated ventilation stations.

The majority of the measure-ments will be made with the vane anemometer utilizing a File Size: 52KB. method should have a thorough knowledge of at least the following additional test methods: Method 1, Method 2. Scope and Application This method is applicable for the determination of gas flow rates in pipes and small ducts, either in-line or at exhaust positions, within the temperature range of 0.

Readings of airflow measurement are in actual feet of air, meaning the measurement is taken at the height where the anemometer is located.

This measurement results in actual feet per minute. Anemometers are placed on the roofs of houses or on top of towers that can be 20 to 50 feet tall. High elevations may give higher wind-speed readings. Here is sketch diagram shows the arrangement of a hot wire anemometer used for the measurement fitted with a wheatstone bridge.

LASER DOPPLER ANEMOMETER AND ITS APPLICATIONS []. It is a very advanced type of anemometer offers the advantage that they do not disturb the flow during the measurement is a optical type of flow meter and it can also visualise fluid as lase.

The Anemometer can be used in combination with various pitot pipes what makes the instrument very useful in air flow measurements of industrial plants.

Add actual pipe size and in each section. Use tabulated data or a diagrams. The anemometer, an instrument found in most weather stations, detects patterns and changes in wind behavior. Due to ever-changing wind currents, anemometers are essential in predicting daily weather forecasts and notifications.

The anemometer family has many branches that use different kinds of technology to determine. The Airflow Instruments Rotating Vanes LCA is a hand held digital Rotating Vane Anemometer used for air velocity and volumetric flow measurements.

PRODUCT DETAILS. An anemometer is an instrument used to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind.

To determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the on: Connecticut Ave, Suite 5N01, CTNorwalk.where V is the wind speed, f is the anemometer's rotation frequency output, and A (slope) and B (offset) are the calibration coefficients.

This linear equation, which correlates the wind speed and the anemometer's output frequency [], must be defined by means of a calibration process [9, 25–27] and was quite early defined for the Robinson-type anemometer [].Cited by: testo vane anemometer for measuring air flow velocity, volume flow and temperature.

Attachable measurement funnels make this ideal for measuring volume flow at ventilation outlets. Also suitable for swirl outlets: thanks to the flow straightener, precise measurements can also be taken at swirl outletsLocation: Plot No.
