Technical Specification


A Hot-Wire anemometer is an instrument for measuring fluid velocity, whether it be of gases or fluids, hot wire or hot film, Hot-Wire Anemometers measure fluid speed using a delicate probe made of thin tungsten/platinum wire, or a thin metallic film. This probe is heated to a temperature higher than average temperature of the fluid. Using sophisticated circuitry, the anemometer stabilizes and maintains the probe temperature at a constant level throughout the measurement. Since the fluid flowing past the probe has a lower temperature than the probe, the film/wire is constantly being cooled by the fluid flow. The higher the velocity, the faster the rate of cooling.
Since the anemometer must maintain the probe temperature at a constant level, it is therefore sensitive to the rate at which it is being cooled, i.e., the fluid velocity. This velocity is translated to a continuously changing voltage which has a nonlinear relationship with the flowing fluid. This voltage then undergoes signal conditioning, to filter out noise and improve the Signal/Noise ratio.
After proper calibration of the probe channels, it is possible to measure fluid velocities with an accuracy of 0.05% or greater, depending upon the measurement range and the quality of the calibration. The response time between measurement and instrument output is very short in comparison with other methods of fluid flow measurement and can reach a minimum of 1/2 microsecond.
The AN-1003 Anemometry system measures at that speed up to 10 channels simultaneously!
The AN-1003 Hot-Wire Anemometer can measure fluid velocities from 0 and up to supersonic speeds. In addition to these inherent qualities of the basic AN-1003 system, there are 14 extra options which can be added to any number of channels. These expand the capabilities of the system, allowing it to make professional-standard measurements in different kinds of fluids.

Another advantage of the AN-1003 is its modularity: channels can be removed or interchanged without disturbing other channels already calibrated for different experiments.

The AN-1003 is being used today at a large number of leading research institutes and universities throughout the world, where, for a number of years, it has proved its value as a reliable and accurate instrument, and has become a valuable research tool for scientists and engineers. Part of the AN-1003's success is due to its user-oriented design, making the system easy and straightforward to use by inexperienced students and professional researchers alike. We hope that you become part of this expanding group of satisfied AN-1003 users.
