Platon Averaging Pitot

Tube: Flo-Bar

DS1710

FLOW RANGES AND MODELS

Flo-Bar Averaging Pitot Tubes are available in three versions,

suitable for different pipe size ranges and flow conditions.

Model PPA uses a 13mm diameter tube and is suitable for

small sized pipes, ducts and ventilation systems. The standard

PPB Flo-Bar is 25mm diameter, covering the mid range of

pipe sizes. Larger ducts such as chimneys or trunk liquid

mains would use the 60mm diameter PPC unit. The graph

shows the maximum water flow rates measurable for the

three Flo-Bar models, for increasing pipe size.

MODELS AVAILABLE

Flo-Bar models are available with different types of pipe installation fittings. The simplest approach is to use a

compression fitting screwed into the pipeline. Alternatively, the Flo-Bar can be supplied flanged. Roxspur can supply the

weld boss or flanged standoff. Where the installation requires the Flo-Bar to be retracted under line pressure, for pipe

cleaning etc, valved retraction headwork options are available, subject to line pressure limitations. For pipe sizes 2" and

below, in line Pitot pipe sections are available. For more complex pipe or duct configurations, multiple Pitot arrays with

flow straighteners are available.

All the above models have the standard options of integral three valve manifolds or alternative impulse line connections.
