A flow nozzle is a flow tube with a smooth entry and a sharp exist. The DP transmitter computes flowrate based on the difference between upstream pressure and downstream pressure. Flow nozzles are mainly used for high-velocity, erosive, non-viscous flows. Flow nozzles are sometimes used as an alternative to orifice plates when erosion or cavitation would damage an orifice plate. They offer excellent long-term accuracy.
