You Should Know IN WHAT Are The Advantages of Ultrasonic Anemometer

Before discussing the benefits of ultrasonic anemometer & ultrasonic wind sensor, let’s see what an anemometer is first. An anemometer is an instrument that measures the air velocity. There are diverse forms of it and among which that the wind cup anemometer is the most commonly used in meteorological stations.

It is mainly composed of three parabolic cone empty cups fixed on the bracket at 120� one another. The concave surface of the empty cup is all facing one direction. The complete sensing part is installed on a vertical rotating shaft. Under the aftereffect of wind, the wind cup rotates round the shaft at a speed proportional to the wind speed.

The anemometer is mainly based on the meter adopts the calorimetric principle to gauge the wind speed. The basic principle is to put a thin metal wire in the fluid and pass the current to heat the metal wire to help make the temperature greater than the temperature of the fluid, so the metal The silk anemometer is called “hotline”.

Once the fluid flows through the metal wire in the vertical direction, it will require away a part of the heat of the metal wire, and the temperature of the metal wire will drop. Based on the theory of forced convection heat exchange, it really is derived that there is a relationship between the heat Q lost by the heating wire and the velocity v of the fluid.

The wind speed sensor can be an intelligent instrument with convenient use, good performance and high reliability. It is usually widely used to measure wind speed in greenhouses, environmental protection, weather stations and breeding places.

There are many types of wind speed sensors, which can be split into Pitot tube wind speed sensors, propeller wind speed sensors, Hall effect electromagnetic wind speed sensors, hot wire wind speed sensors, and ultrasonic wind speed sensors. Compared with the original wind speed meter, the ultrasonic wind speed sensor has the advantages of good measurement accuracy and multiple functions, and the structure of its probe is not at all hard.

ultrasonic anemometer In many applications, it replaces the original wind speed and direction sensor. People will choose ultrasonic wind speed sensors in some field precision measurement tasks, such as urban environmental monitoring, wind power generation, weather monitoring, bridges and tunnels, marine ships, aviation airports, various fan manufacturing industries, and industries that require exhaust systems.
