The Accusonic Model 7915 Cavitation Monitoring System (CMS) monitors the cavitation that occurs on the surface of turbine runner blades
The Accusonic Model 7915 Cavitation Monitoring System (CMS) monitors the cavitation that occurs on the surface of turbine runner blades. The system is used to:
  • Avoid excessive cavitation
  • Reduce erosion damage
  • Identify best operating zones
  • Indicate cumulative damage
  • Improve unit performance
  • Determine optimum cam position

When permanently installed, the system continuously measures the relative magnitude of the cavitation levels to allow the user to optimize unit operation and to log cavitation levels on specific units to predict maintenance schedules.
The sensor is non-intrusive and can be installed without taking the unit out of service.

A red-yellow-green bar chart display of current cavitation levels of each unit are displayed for the operator. An accumulated cavitation value, representing relative erosion since the last repair work, is also displayed and recorded.
Selectable screens display:

    Current unit operation and accumulated cavitation
    Historical trend data
    Individual unit cavitation characteristics (cavitation vs. power)

The 7915 can be used in a portable mode to map the cavitation characteristics of several units in order to define operating regions that will minimize cavitation and unit damage.
The system may also be used in fish mortality studies to help quantify the effects of cavitation on fish.
