Air Mass Flow Meter and Compressed Air Flow Meters | Sage ...

Dry air consists of nitrogen (78%), oxygen (21%), argon (>1%), and trace amounts of carbon dioxide, methane, hydrogen, helium, and neon. While most mass flow meters measure the flow rate at the actual conditions where the measurement is taking place, the general practice relates the flow rate to STP conditions, requiring knowing the air’s pressure and temperature at the measurement point.

Air flow sensors and air flow meters - Product overview ...

Air flow sensors and volume flow meters are suitable for measuring and controlling volume flows in ventilation and air conditioning systems. Volume flow sensors measure the total pressure, the static pressure of the air flow and the average air velocity. Even very low air velocities of up to m/s can be measured by a special shape of the sensor. In combination with the PID controller type ...

Air Flow, Air Systems, Pressure, and Fan Performance

This curve shows the relationship between the air flow rate and the pressure of an air system. Complex systems with branches and junctions, duct size changes, and other variations can be broken into sections or sub-systems. Each section or sub-system has its own system curve. See the diagram below for an illustration of this concept. Fan Laws. Use the Fan Laws along a system curve. If you ...
