Itabar 150546740 Flow Sensor

Itabar 150546740 Averaging Pitot Tube Flow Sensor

The Itabar 150546740 Flow Sensor is a heavy-duty, averaging pitot tube differential pressure sensor designed by Intra-Automation for continuous volumetric and mass flow rate measurement in high-pressure steam, gas, and liquid pipelines. Engineered with a proprietary sensor profile, the 150546740 samples dynamic and static pressure across multiple port locations in the pipe cross-section to deliver averaged, highly accurate differential pressure signals even under turbulent or non-symmetrical flow profiles.

Constructed for high-stress marine and heavy industrial environments, this unit is engineered to withstand working pressures up to 420 Bar (6092 PSI) at 38°C and continuous operating temperatures up to 232°C (450°F). By inducing minimal permanent pressure drop compared to conventional orifice plates or Venturi tubes, the Itabar 150546740 minimizes pumping energy loss across high-pressure boiler feed, hydraulic, steam distribution, and fuel oil transfer lines.

Model Details

• Manufacturer: Intra-Automation GmbH / Itabar
• Model Series: Itabar Dynamic Pressure Insertion Sensor
• Manufacturer Part Number (MPN): 150546740
• Sensor Type: Multi-Point Averaging Pitot Tube Differential Pressure Sensor

Key Features

1. Extreme Pressure Rating: Verified nominal pressure rating of 420 Bar (6092 PSI) at 38°C (100°F) for deep-water marine systems and high-pressure hydraulic header lines.
2. Elevated Temperature Tolerance: Continuous process temperature rating up to 232°C (450°F), preventing seal degradation and structural fatigue in superheated steam and thermal fluid piping.
3. Multi-Point Averaging Profile: Utilizes internal averaging chambers across four upstream impact ports and downstream static ports to eliminate velocity profile skew without requiring excessive straight pipe runs.
4. Low Permanent Pressure Loss: Aerodynamic profile shape minimizes system head loss, reducing fuel and electrical consumption on high-capacity boiler feed pumps and turbine supply lines.
5. Solid Stainless Steel Construction: Heavy-wall stainless steel body provides superior resistance to cavitation erosion, thermal shock, and aggressive marine or chemical fluids.

Applications

• Marine Engine Room Auxiliary Systems: Main boiler steam supply headers, exhaust gas scrubbing water monitoring, heavy fuel oil (HFO) transfer, and high-pressure ballast flow lines.
• Power Generation & Offshore: Superheated steam lines, feedwater pump output monitoring, high-pressure natural gas metering, and condensate return lines.
• Chemical & Heavy Industry: High-pressure hydraulic circuits, compressed air header distribution, thermal oil circulation, and high-velocity process gas lines.

Frequently Asked Questions

What is the maximum operating pressure for the Itabar 150546740 Flow Sensor?

The Itabar 150546740 is rated for a maximum operating pressure of 420 Bar at 38°C (6092 PSI at 100°F), making it suitable for ultra-high-pressure hydraulic systems, boiler feed lines, and offshore gas processing.

How does an averaging pitot tube like the Itabar 150546740 differ from a standard orifice plate?

Unlike orifice plates, which create significant flow restriction and high unrecoverable pressure loss, the Itabar 150546740 uses an aerodynamic averaging rod inserted across the pipe diameter. It measures dynamic and static pressure across multiple points with minimal permanent pressure loss, reducing system pumping power requirements.

Can the Itabar 150546740 be used for superheated steam applications?

Yes, the Itabar 150546740 features a continuous temperature rating up to 232°C (450°F) and all-stainless steel construction, making it ideal for superheated steam, saturated steam, and hot thermal oil lines.
