Patent Number: 6,253,624

Title: Friction flowmeter

Abstract: A pressure transmitter produces signals indicative of a flow in a pipe. The transmitter has a pressure sensor that is fluidly coupled to two ports in the pipe, and the pipe has a substantially constant cross-section between the two ports. Aspects of the invention include a circuit coupled to the pressure sensor that produces a digital value related to the fluid flow as a function of the pressure difference between the two ports.
