About the Daniel Flow Nozzle
First patended in 1979, the flow nozzle is a highly, versatile flow meter that blends the simplicity of an orifice plate with the hydrodynamics of the venturi tube. Similar to the orifice meter, the flow nozzle has a short length that allows the meter to be installed in between flanges. However unlike the sharp edge of an orifice plate, the flow nozzle has a gradual, sloping profile that is similar in function to a venturi tube. This unique combination lends itself highly useful in high temperature, high pressure systems where high velocity fluids need to be measured. Flow nozzles are commonly used in power plants, refineries and processing facilities.
Depending on system requirements, Daniel offers flow nozzles in the following configurations: flanged, tapped, weld-in, and holding ring.
