Model VISSL Venturi Classical, Insert Flow Meter

 

Model VISSL Venturi Classical, Insert Flow Meter

Model VISSL Venturi Classical, Insert Flow Meter

 

The Venturi Model VISSL (Insert Type Classical Venturi Design) is a Hershel/Classical design differential pressure flow device. The insertion style meter adds only the thickness of the meter center flange to the overall length of the pipe.  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.
