    摘要: Disclosed is an apparatus for measuring a fluid flow through a pipe of a semiconductor manufacturing device, in particular a coater or a bonder. The apparatus includes a sealing structure arranged in the pipe, a flow structure having a fluid inlet arranged upstream of the sealing structure and a fluid outlet arranged downstream of the sealing structure, a first chamber arranged in the pipe upstream of the sealing structure, and a second chamber arranged in the pipe downstream of the sealing structure, and a measuring device, wherein the measuring device is adapted to measure a first fluid pressure in the first chamber and a second fluid pressure in the second chamber, wherein the measuring device is configured to determine the fluid flow based on the first and second fluid pressure.
