How to Calculate Flow Rate

The flow rate can be determined from the sensor’s output voltage using the following formula:
$text{Flow Rate} = frac{(text{VOUT} - 1 text{V})}{4 text{V}} times text{Full Range Flow Rate}$
Example Calculation:
For a CAFS5032AV sensor with a full range flow rate of 1000 SLPM, if the output voltage is 2.5V, the instantaneous flow rate can be calculated as:
$text{Flow Rate} = frac{(2.5V - 1V)}{4V} times 1000 text{SLPM} = 375 text{SLPM}$
