Verification / Proof of Nozzle orifice diameter
 
Rosemount Orifice plates of various bore sizes are used to prove the nozzle orifice diameter in a real time setting. An Orifice Flange Union holds orifice plates in place for easy installation.
 
Each orifice plate is inscribed the bore diameter ranging from 12mm to 100mm and other pertinent manufacturer data.
In our spray test set-up, when a pre-set pump pressure flows thru a selected orifice plate of a certain bore size, the flow  meter will register the appropriate flow reading
 
Repeated test of changing the orifice plate of various bore diameter enable accurate flow confirmation.
The accuracy shall be within 0.5% of the actual flow or 0.25% over the flow range.
Nozzles are designed in accordance to ASTM E799-92 (Pre-approved 1998) as per "STANDARD PRACTICE FOR DETERMINING DATA CRITERIA AND PROCESSING FOR LIQUID DROP SIZE ANALYSIS"
