发明名称 Friction flowmeter
摘要 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.
