Abstract
A flowmeter is provided that comprises a leadframe assembly () and a body () disposed at least partially around the leadframe assembly (). The body () has a flow passage therethrough that comprises a first channel () having a first port (), a second channel () having a second port (), and a flow altering element () disposed within the second channel (). First and second pressure sensors (and) are disposed within the body () and coupled to the leadframe assembly () for measuring a first pressure within the first channel () and a second pressure within the second channel (), respectively. An integrated circuit (), which is coupled to the leadframe assembly (), to the first pressure sensor (), and to the second pressure sensor (), is configured to determine the rate of flow through the flow passage from the first pressure and the second pressure.
