Flow Nozzle

Parsjahd Products - Flow Nozzle

The flow nozzles, more costly than other orifice due to their structure, are suited for determining the flow rates of fluids flowing at high temperature and high pressure.

Under the same measuring conditions, a flow nozzle has a higher mechanical strength, can permit the flow of more than 60 percent grate volume of a fluid, and can measure the flow rates of fluids containing solid particles less disturbed, than an orifice having the same bore.


Thus, they are suited, in addition, for high speed flowing fluids. We can supply not only single flow nozzles, but also flow nozzles having welded short pipes on both their upstream and downstream sides.
