Abstract:
A transmitter for producing signals indicative of a flow in a pipe, the transmitter comprising:first and second ports for fluidly connecting the transmitter to a first location and a second location in the flow that are separated by a pipe section having a substantially constant cross-sectional area between the two locations the first port and second port being separate from each other such that flow is prevented from moving between the first port and the second port within the transmitter;a pressure sensor, fluidly coupled to the first and second ports, adapted to provide a sensor output in response to a pressure at the first port and a pressure at the second port; anda circuit, coupled to the pressure sensor, for receiving the sensor output and for providing at least one digital value that is related to the flow and is a function of the pressure at the first port and the pressure at the second port.
