PCE-VA 20-SET is a multifunction air flow meter with capture hoods for assessing and balancing heating, ventilation and air conditioning or cooling (HVAC) systems. This combined hygrometer-anemometer-thermometer possesses a 10 cm / " diameter fan impeller and a bright backlit LCD.
Sensirion's inspiratory flow sensors are typically used inside the ventilator to measure the individual air/O 2 /heliox gas lines as well as the total flow of the mixed gas before delivery to the patient. Our sensor platform includes sensors for flow measurement at ambient pressures (SFM3xxx series) and sensors for placement on the high-pressure side upstream of the proportional valves (SFM4xxx).

About Anemometers & Airflow Meters. An extremely common tool for use by HVAC professionals, anemometers are designed to calculate the overall speed of wind passing through a specific area. They are most commonly associated with testing air conditioning and ventilation systems for correct airflow in order to ensure comfortable environments.
Display temperature and airflow or temperature and relative humidity simultaneously. Measure wind velocity from to 20m/s (80 to 4000 ft/min), relative humidity from 0 to 100% RH. Used to calculate air, dew point, wet bulb and wind chill temperature across a range of -20 to 60°C (-4 to 140°F).
Ventilation and air-conditioning equipment, also known as air-handling units, exchanges the used room air with fresh air from the outside. Rooms are thus adequately ventilated and the air quality is improved.

Follow the horizontal axis across to 3 and go down until you hit the diagonal line, which brings you to -21. Then do the same for 1m in distance. This will give you a value of -11. -11 subtracted from -21 = -10. Subtract -10 from the 1m value (40) = 30 dB (A) at 3m from the fan. If you have the dB value then use this graph to find the dB (A) at ...
Air flow measurement – ventilation. Ventilation is important for maintaining safe operations underground. Correct levels of ventilation must be ensured at all times. Therefore, the supply and exhaust air flows must be measured regularly. Based on the ultrasonic measurement principles, the FLOWSIC200 and the intrinsically safe FLOWSIC60 (Ex ia ...
Precise calculation is tricky. A general example: In a 25 by 40-meter workshop with a ceiling height of six meters, there are five welding stations. A technical workshop ventilation system should be designed to achieve a volume flow of at least 30,000 m³/h – that’s an air exchange rate of five. This means that the total air volume of the ...
Air flow sensors are suitable for the measurement and control of air flows in ventilation and air-conditioning systems. The air flow calculation is made using the ventilator constant (K factor). For operation in ventilation pipes and ducts, air flow sensors are available with special measuring probes.

Figure 1 shows the schematic construction of a ventilator with the typical air flow/sensor positions. Technical challenges. The complex breathing circuits have a wide range of composition variability due to the different types of tubing, humidifiers, filters and adapters used. This often results in leaks and imperfections, which is why the inspiratory flow rate (I) sometimes differs ...
With the A2G-25, air flows up to 200,000 m3/h and differential pressures up to 7,000 Pa can be measured. Description The model A2G-25 air flow meter is used for measuring air flows of gaseous media in ventilation and air-conditioning applications. The air flow is measured by determining the differential pressure and multiplying it with the K ...
· Airflow is the volume of air moved by a fan per unit of time, usually expressed in cubic feet per minute (cfm) or meters cubed per second (m³/s). For general ventilation, airflow can be calculated by: Area method; Air change method; Occupancy method; Heat removal method; Area Method . Derives the ventilation rate from the area of the space (in square feet) to be ventilated multiplied by the ...
· 【Airflow CFM Meter】BT-846A wind speed gauge measures Wind flow range: CFM 0-999900 ft3/min, Resolution: , Air flow area : ft2. You can just set the cross sectional area of the register or vent, the air volume will display in CFM/ CMM synchronously during the air flowing measurement.
The model A2G-25 air flow meter is used for measuring air flows of gaseous media in ventilation and air-conditioning applications. The air flow is measured by determining the differential pressure and multiplying it with the K factor.
For more than half a century, we have earned a reputation for quality airflow measurement instruments. It began in 1955, when a single airflow measurement and fan design expert founded Airflow Developments Limited. The company was hailed as innovative and easy to use.
