The most common unit of air velocity or distance travelled per unit of time is feet per minute (FPM). The amount of air that flows past a point in a duct during a given unit of time is calculated by multiplying air velocity by the area of the duct.
The usual unit of volume flow measurement is cubic feet per minute (CFM). The following techniques are the most popular and straightforward ways to gauge, estimate, and set airflow: Vane Rotating Anemometer (Measurement, mid airflow range) Drop in pressure across the drier evaporator coil (estimate) technique of total external static pressure (estimate)
The Global Airflow Measuring System market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The Next Generation Outdoor Airflow Measuring System, model OAM II, is made available by Air Monitor. Air Monitor will be able to strengthen their position as the industry pioneer in precise and trustworthy outdoor airflow measurement thanks to the improvements made to the OAM II.
Some notable features include: True Dual Channel – increased flow ranges and additional I/O to handle two entirely separate systems; All Single Channel units now have what used to be the Extended Flow Range.
To support all configurations, new model codification. Accurate flow measurement is made possible by the OAM II airflow measuring device in difficult outdoor air applications as well as other airflow applications with constrained straight ducts.
The system consists of an exclusive uni-sensor airflow sensor from AMC and a customised multifunction transmitter with precise ultra-low differential pressure transducers.
Native BACnet® or MODBUS® and four analogue outputs are offered as standard. Flow, temperature, velocity, dP, absolute pressure, and operational status are among the data that are displayed.
The OAM II has been specifically designed to tackle the difficulties present in existing outdoor air measurement techniques:, The effects of short, straight duct runs, which are common in outdoor air applications, are minimised by measurements over a fixed entrance.
The impacts of condensing moisture, variable directional wind loads, and gusts are all considerably diminished by the uni-sensor. The accuracy and performance of other technologies will be severely hampered by moisture and particulate contamination.
