STEAM FLOW DETECTION
Steam flow detection is normally accomplished through the use of a steam flow
nozzle.

DESCRIBE density compensation of a steam flow
instrument to include the reason density compensation
is required and the parameters used.
The flow nozzle is commonly used for the measurement of steam flow and other high velocity
fluid flow measurements where erosion may occur. It is capable of measuring approximately
60% higher flow rates than an orifice plate with the same diameter. This is due to the
streamlined contour of the throat, which is a distinct advantage for the measurement of high
velocity fluids. The flow nozzle requires less straight run piping than an orifice plate. However,
the pressure drop is about the same for both. A typical flow nozzle is shown in Figure 8.
