ABB FPD550 Compact Averaging Pitot Flowmeter

The ABB FPD550  PitoMaster is an averaging pitot tube-based flowmeter designed to greatly simplify specification, installation and commissioning

PitoMaster is a one-piece flowmeter assembly with the following features:

  • Averaging Pitot tube assembly with choice of pipe sizes from DN100 to DN 600 (4 to 24 in.)
  • Threaded or flanged pipe connection
  • Integral 3-valve instrument manifold (optional 5-valve manifold available
  • Integral DP or multivariable transmitter, factory-fitted to manifold
  • Optional integral mineral-insulated temperature element for corrected volume / mass calculations; optional integral temperature transmitter
  • Integral DP or multivariable transmitter, factory fitted to manifold
  • Fully leak tested
  • New "through-the-glass" (TTG) keypad technology enables configuration without the need to remove the transmitter cover in hazardous areas.
  • Factory configuration saves the user time during commissioning and ensures that the flowmeter output span truly matches that of the application  flowrate.

Dual averaging feature
- gives improved accuracy with asymmetric flow profie
Factory acceptance report
- supplied with report detailing results of critical inspection checks, plus certification data


PitoMaster avoids many of the difficulties involved in the sizing, selection, procurement, installation and commissioning of conventional DP flowmeter installations

  • With all the major components in one assembly, PitoMaster eliminates the problems of sourcing multiple components. It provides large savings in cost and time due to the simplicity of purchasing, design and installation.
  • Integral transmitter and manifold with compact tapping connections eliminates the need to run and connect impulse piping and offers:
    -guaranteed accuracy of positioning and installation of the tapping points
    -Integral transmitter and manifold with compact tapping connections eliminates the need to run and connect impulse piping and offers:
    -reduced possibility of impulse line blockage — reduced number of potential leakage points
    -The assembly is pressure-tested in the factory, ensuring the connections between the tapping points and the transmitter are completely free of leaks.
    -The 'Plugged Impulse Line Detection' (PILD) feature generates a warning via HART communication if either or both of the impulse lines become fully or partially obstructed (for example, by foreign material or ice). The meter can also be configured to drive the analog output signal to the 'Alarm current'.
