Model SSL Venturi Classic Flow Meter

The Venturi Model SSL (Classical Venturi Design) is a Hershel/Classical design differential pressure flow device. The Venturi flow meter restricts the flow at its throat, increasing the velocity of the fluid, and measures the pressure difference of the unrestricted flow and restricted flow. The meter's throat can be designed to meet the flow measurement application optimizing the meter's accuracy and permanent pressure loss.
