The Diagnostics Results are represented as 3 Points and a Box. If the points remain in the box, this ensures good flow measurement.
  • A Downstream Pressure Tap Allows 3 DP's to be Read.
  • The Pressure Field Through the Meter is Monitored.
  • The Diagnostic System Multiplies the Meters Capability.
  • 3 DP's are Compared to Assure Correct Meter Operation.
  • A Simple Live Diagnostics Plot is Shown in the Control Room.

Cone Flow Meter Problems that Produce a Warning with Diagnostics Include:

  1. Incorrect Inlet or Cone Diameter Keypad Entry.
  2. Two-Phase Flow.
  3. Debris Trapped at the Cone.
  4. Contamination Build-Up Through the Meter.
  5. Blocked Impulse Lines.
  6. Saturated or Drifting DP Transmitter.
  7. Incorrect Discharge Coefficient Keypad Entry.
  8. Incorrectly Spanned DP Transmitter.
  9. DP Below DP Transmitter Range.
  10. Damaged Cone Element. etc.

DP Diagnostics Can Retrofit a Diagnostic System to an Existing 3rd Party Cone Flow Meter if a Downstream Tap is Supplied and the Meter can be Made Available for Calibration.
