<p>PURPOSE:To obtain an air quantity measuring machine which has a simple constitution and is compact and inexpensive for measuring the quantity of system cooling air. CONSTITUTION:This air quantity measuring sensor is provided with an opening 13 that can be brought into close contact with the front face panel 8 of an ad-on system 1 which is an object to be measured and a speed sensor 11 installed to an opening 14 which is faced to the opening 13 and has a fixed cross-sectional area for measuring the speed of air (fluid) passing through an air channel 10 and the opening 14. The quantity of the air can be accurately obtained by performing conversion on the basis of the fixed cross-sectional area of the opening 14 and the value of the speed sensor 11.</p> |
