Standard orifice plate and ISA1932 nozzle |
The standard orifice plate has the merits of high measuring assuracy,wide application range and lower price,etc.Its pressure methods have "corner","flange" and "D-D/2"
ISA1932 nozzle has the merits of high measuring accuracy,small press loss and long life,etc.Its pressure method has "corner joint pressure"
1 The corner orifice plate and the ISA1932 nozzle component are widely use for the flow measurement,the flow control and the flow adjustment of vatious amboceptors in the industries of electric power,metallurgy,textile and light,etc. |
