Flow Nozzle
About Flow Nozzle
The form of a flow nozzle is not prone
to solid particles or bubbles of gas in a flowing fluid sticking in
the flow restriction, and so in this respect it is superior to the
orifice plate. Its useful working life is also greater because it does
not get worn away in the same way as an orifice plate. These factors
give the instrument a greater measurement accuracy. However, as the
engineering effort involved in fabricating a flow nozzle is greater
than that required to make an orifice plate, the instrument is
somewhat more expensive. In terms of the permanent pressure loss
imposed on the measured system, the flow nozzle is very similar to the
orifice plate. A typical application of the flow nozzle is in
measurement of steam flow.
