Hi All!

In the wonderful world of pressure sensors there are basically 3 types. Absolute, Gage, and Differential. All are easy to understand as to what they do and what they measure. The question is when you are using a differential sensor from what I understand you have two different pressures being applied to a single membrane thus one pressure is subtracted from the other. Thus your sensor is providing only one pressure measurement number? If this is true then how can you convert this one pressure number into speed? Inquiring minds wish to know. Thanks, Ed
