Air Velocity Meter Anemometer Calibration

Air Velocity Meter Anemometer Calibration Lab Services

Quick-Quote-ButtonCalibration capabilities include thermal anemometer and vane anemometer.

Our GDJ 360 Benchtop Wind Tunnel is designed to give a highly uniform flow rate with our test section being over 152mm with a variable adjustable speed from 0 to 6,000 FPM. Each measurement is directly compared against our ISO: 17025 calibrated anemometers.  We know how critical your air velocity and wind speed equipment is to your work, we turn around your anemometers in 7-10 days. Our calibrations stand up to any quality audit or customer inspection and are NIST-traceable.

Thermal Anemometer Calibration

Thermal anemometer or "hot-wire" anemometer calibaration measures the flow speed by a small probe inserted in the flow. The sensitive element of the probe is a small wire about 1 mm wide and a few thousands of an inch thick that is heated at a constant temperature of about 200 Celsius.

Vane Anemometer Calibration

Wind Vane Anemometers are further inspected for physical defects such as burs, cracks or chips in the vane blade. Upon completion of testing, all data is then recorded and compared to manufacturer specifications or client requested specifications.

Alternate Terms for Anemometers

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

 

What is an Anemometer?

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.

 

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.

 

What is the significance of a built-in IR thermometer?

Having an IR thermometer as part of an Anemometer offers the user several important benefits:

  • Two tools in one
  • Save time and cost
  • Check for hot spots in duct work, electrical panels, and wiring conduits

 

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
