Orifice and Orifice assemblies

Spraytech Systems orifice plate is a device used for measuring flow rate. Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the it. It uses the same principle, namely Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the velocity increases, the pressure decreases and vice versa.

Spraytech Systems Orifice Performance :
Principally, Spraytech Systems orifice plate is a precision instrument. In best circumstances, the inaccuracy of Orifice plates can possibly fall in the range of 0.75-1.5%. However, there are numerous error causing conditions which can terribly affect the accuracy of Spraytech Systems Orifice plate.

Following factors are used to judge the performance of Spraytech Systems Orifice plate :

• 1. Precision in the bore calculations
• 2. Quality of the installation
• 3. Condition of the plate itself
• 4. Orifice area ratio
• 5. Physical properties of the fluid flow under measurement, refer the free length table mentioned below
