controlling mass flow rate

controlling mass flow rate

(OP)
Hello is there any way that we can control mass flow rate of air coming with varying temperature? If there was a temperature range of -20 to +100 C I'm puzzled on how we can meaure flow rate with a varying density of air.  Is there such a device that can measure it, say with a known CFM?  Thanks

RE: controlling mass flow rate

The Mass Air Flow (MAF)sensor on your car does this.

Many companies make mass flow controllers where a flow meter is connected to a servo valve and can provide a constant flow of gas.
