+/- 0.25% Always Calibrated
Highest Accuracy / Repeatability
- Line size: 4 to 28 inches
- Head loss (permanent pressure loss) in % of Differential: 60% to 85% (18% to 25% with optional outlet diffuser cone), Beta Dependent
- Recommended Application, THROAT Reynolds Number: Greater than 500,000
The ASME PTC-6 Throat Tap Flow Nozzle provides the highest possible dP device accuracy and precision which is needed for the testing of steam turbine efficiency as prescribed in the ASME PTC-6 2004 Performance Test Code. The PTC-6 Flow Nozzle is supplied complete with integrated up/down pipe spools, a flow conditioner and with an optional nozzle outlet diffuser cone for considerably reduced pressure loss.
All PTC-6 Flow Nozzles supplied by Primary Flow Signal are guaranteed to meet the strict laboratory calibration criteria required to maintain the uncertainty needed for turbine performance testing.
