Thermo Anemometers

Triplett offer a variety of thermos anemometers for sale. They measure air velocity, air temperature, relative humidity, dew point, and so on. They are useful for crucial indoor as well as outdoor applications such as wind power monitoring, sailing, vehicle aerodynamics, and so on. They come with an LCD display and a protective housing. Most models have an automatic power off feature and are water resistant. Their air velocity range depends on the distance covered. The accuracy rate for most models is around ±3%.

Anemometers are devices which measure wind pressure, flow rate, and so on in feet per minute (FPM). This is done with the help of a magnetic sensor. Thermo anemometers measure the amount of heat displaced from the object or area.

Know More About Triplett Anemometers

What is Anemometers?

Anemometers measure the speed (velocity) of moving air. Thermo-Anemometers also measure temperature by way of a thermometer located in the Anemometer sensor. The measurement units for Anemometers include: Feet per minute (ft/min), meters per second (m/s), kilometers per hour (km/hr), miles per hour (mph), nautical miles per hour (knots), and Beauforts.

Anemometers are used to measure various parameters related to wind pressure, temperature, wind chill, and so on. They measure the speed (velocity) of moving air. We offer these anemometers with digital measurement feature. They are compact and handy devices and some models are called pocket anemometer. In indoor areas, it is used in HVAC systems, exhaust systems, duct airflow, and so on. Outdoor, they are used in various segments such as atmospheric wind measurement, weather stations, and so on. Thermal anemometers have a wire element heated to some specific temperature. They have advanced features and functionalities such as an LCD display, data logging ability, and so on.

What are the alternate Terms for Anemometers?

  • Air Flow Meters
  • Air Velocity or Wind-speed Meters
  • Wind cups or weathervanes

How does an Anemometer measure moving air?

Anemometers measure moving air with a rotary sensor which acts very much like a weathervane and can be likened to the blades of a fan. The vane freely rotates in response to air flow and as the air moves through the vane the blades turn in proportion to the speed of the air.

What is CFM / CMM?

Cubic Feet per Minute (CFM) or Cubic Meters per Minute (CMM) are units of measure for Air Volume measurements. This is a measurement of the quantity of moving air through an air duct, passageway, or enclosure. In order to accomplish this, the area of the duct must be measured. The area value (in ft2 or m2) is entered by the user by push button or keypad into the meter and an air velocity measurement is taken. The meter then calculates the CFM or CMM automatically.

Built-in non-contact IR Thermometer, Used in HVAC applications measuring airflow from heating vents.

What are the Typical Anemometer Applications?

  • Air duct measurements
  • Positive pressure tests in clean rooms
  • Fume hood testing and verification
  • Automobile engines analysis
  • Automobile passenger compartment tests
  • Ionizer flow output monitoring
  • Ventilation system inspection

How do thermal anemometers work?

Thermal anemometers mostly function automatically and digitally. It works on how the electrical resistance of a metal wire impact the air flow and velocity. When the air flows over this device, it has a cooling effect. This is called as constant temperature anemometer, wherein the cooling effect of the current is balanced by the current flowing through the metallic wire. The value obtained is saved into the device memory and later used for research and analysis.

What units do anemometers measure?

The measurement units for anemometers are feet per minute (ft./min), meters per second (m/s), kilometers per hour (km/hour), miles per hour (mph), nautical miles per hour (knots), and Beauforts. This depends on the area or part under consideration and also the height above sea level.

How does an anemometer measure CFM?

CFM stands for Cubic Feet Per Minute. This is a unit commonly used for airflow based machines such as HVAC systems, compressors, and so on. This is an important aspect in deciding size and ventilation of such equipment. It gives a volumetric flow rate value of air moving in and out of a particular space. To measure CFM, the area in square feet needs to be considered. Measure the velocity at various points such as corners, ducts, and so on. Find out the average velocity in Feet per Minute (FPM). Multiply the value in FPM by the area where measurements are conducted. This is some portion of the total area. This will give you the airflow value in CFM.
