Abstract
Pressure sensors that may be used in flowrate monitoring or measuring systems, where the pressure sensors may enable simple, low-cost designs that are readily implemented. One example may provide a pressure sensor having a built-in flow path with a dimensional variation. Pressures of a fluid on each side of the dimensional variation may be compared to each other. The measured differential pressure may then be converted to a flowrate through the flow path.
