Accuracy and Characteristics

Very High Accuracy with the Ellipse
The Ellipse offers NIST traceable accuracy for each application of compensated mass flow measurements and rate of flow measurements. The wide 17:1 turndown range offers a linearized curve programmed into the multi-variable transmitter or the Preso MFC computer.

Characteristics:

• NIST traceable calibration
• Accuracy ±0.75% or better
• Repeatability. ±0.1% of readings
• Turndown ratio: 17:1 (K vs Re#)
• Direct transmitter mount with multi-variable technology
• True static pressure measurement
• Single point pipe entry for: DP, temperature and static pressure
• Airfoil characteristics offer very low permanent pressure loss and eliminate noise transmission
• Typical: 3% of DP in a 12" (300 mm) line - the lowest in the industry
• Reduced pumping costs
• Easy to install
• Maintenance free and self cleaning
• Less affected by upstream piping
• No dampening software required
• Hot tap models can be installed without system shut-down
