You Should Know About What Are The Benefits of Ultrasonic Anemometer

Before discussing the advantages of ultrasonic anemometer & ultrasonic wind sensor, let’s see what an anemometer is first. An anemometer can be an instrument that measures the air velocity. You can find diverse types of it and among which that the wind cup anemometer is the most commonly found in meteorological stations.

It is mainly made up 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 whole sensing part is installed on a vertical rotating shaft. Under the effect of wind, the wind cup rotates around the shaft at a speed proportional to the wind speed.

The anemometer is mainly using the meter adopts the calorimetric principle to measure the wind speed. The basic principle would be to put a thin metal wire in the fluid and pass the existing to heat the metal wire to make the temperature greater than the temperature of the fluid, therefore the metal The silk anemometer is called “hotline”.

When the fluid flows through the metal wire in the vertical direction, it will require away a part of heat of the metal wire, and the temperature of the metal wire will drop. According to the theory of forced convection heat exchange, it could be derived that there is a relationship between your heat Q lost by the heating wire and the velocity v of the fluid.

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

There are many types of wind speed sensors, which may 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. Weighed against the original wind speed meter, the ultrasonic wind speed sensor has the benefits of good measurement accuracy and multiple functions, and the structure of its probe is relatively simple.

In lots of 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 for example urban environmental monitoring, wind power generation, weather monitoring, bridges and tunnels, marine ships, aviation airports, various fan manufacturing industries, and industries that want exhaust systems. ultrasonic wind sensor
