Preso AHL – Annular Hot Tap

Preso’s patented elliptical design outperforms and provides greater accuracy than traditional differential pressure flow measurement devices. This differential pressure flow meter is designed with a series of ports facing the upstream velocity pressures, as well as flow sensing ports strategically located ahead of the trailing edge flow separation.

Product Features:

• -Hot-tap model installs without system shutdown
• -Single point pipe entry for DP, temperature and static pressure
• -Pipe Sizes: 2 to 72 inches (50 to 1829 mm)
• -Pressure: 800 PSI (5515 kPa) maximum
• -No dampening software required
• -Lowest pressure loss in industry (typically 3% of DP in a 12 line) due to its patented aerodynamic profile
• -Optional NIST traceable calibration
