digital air flow meter

A digital air flow meter refers to a flow meter that can accurately measure air or compressed air inline. Industrial Digital air flow meters can be divided into mass flow meters or volume flow meters.

What Is Digital Air Flow Meters?

The digital air flow meter is also a digital gas flow meter. The digital air flow meter can measure and display parameters such as mass flow, volume flow, gas temperature, atmospheric pressure and gas pressure of air or other gases. Such as argon, hydrogen, nitrogen, etc.

A digital air flow meter is different from a mechanical gas flow meter. The first is because of the local digital display. For example, a vortex flowmeter, or a handheld gas mass flowmeter. The parameters of the gas pipeline can be displayed locally. The second is because of the signal output. Mechanical gas flow meters cannot support signal output. But digital air flow meter generally supports signal output. Convenient for monitoring system or control system management. Such as 4-20mA, RS485 and so on.

CFM is a common imperial flow unit, cubic feet per minute.
For a certain volume of air flow passing in a unit time, m3/h air volume unit is generally used in China. Other countries also use the British air volume unit cfm (cubic foot per minute). That is ft3/min cubic feet/minute,
1CFM=28.316846592 L/MIN=0.028316847 m3/min

CFM traffic is divided into SCFM and ACFM.

LPM is liter/minute.

Liter/minute to Cubic Meter/hour Conversion Table

Liter/minute [L/min]Cubic Meter/hour [m^3/h]
0.01 L/min0.0006 m^3/h
0.1 L/min0.006 m^3/h
1 L/min0.06 m^3/h
2 L/min0.12 m^3/h
3 L/min0.18 m^3/h
5 L/min0.3 m^3/h
10 L/min0.6 m^3/h
20 L/min1.2 m^3/h
50 L/min3 m^3/h
100 L/min6 m^3/h
1000 L/min60 m^3/h

How to Convert Liter/minute to Cubic Meter/hour?

1 L/min = 0.06 m^3/h
1 m^3/h = 16.6666666667 L/min

Example: convert 15 L/min to m^3/h:
15 L/min = 15 × 0.06 m^3/h = 0.9 m^3/h
