  2. Seal Leakage Measurements

  3. Seal Location

  4. Seal Leakage Vent Line

  5. Seal Leakage is a Problem Elsewhere

  6. Lost Dollars

  7. Flow Sensing via Flow Column • Works well when measuring dry clean gas • Low cost easy to understand Flow

  8. Flow Sensing via Turbine Flow Meter • Multiply the velocity times the cross sectional area of the turbine provides the volumetric flow rate Excellent measurement accuracy for clean gases! Moving parts subject to wear Drag, a particular problem at low flows Buildup caused by oily gas which erode the accuracy

  9. Flow Sensing via Thermo Mass Flow Technology

  10. Number of Leaking Cylinders in a Station No. of engines x No. of cylinders = 24 leaking seals

  11. Package Vent Leakage Meters Flow Flow: 0.2 to 10 SCFM Input Power: 9 V rechargeable batt. Operating Temp: 40 to 120 F Class 1 Div.II rated pending Option Output: 4 to 20 mA Model 8510-002 Flow: 0.2 to 10 SCFM Input Power: 24 Vdc Operating Temp: 40 to 120 F Output: 4 to 20 mA Class 1 Div.I rated Option: remote meter Flow Model 8520-002
