Platon Averaging Pitot Tube: Flo-Bar

TT Electronics. 

Platon Averaging Pitot

Tube: Flo-Bar

DS1710

READOUT OPTIONS

Differential Pressure

Transmitter

The most frequently used

measurement system with a

Flo-Bar flow sensor is a

conventional DP transmitter,

either mounted directly on

the Flo-Bar manifold, or

separately mounted and

connected to the Flo-Bar via

impulse tubes.

Micro-Bar Electronics

For dry gas flow

measurement the Micro-Bar

low range differential

pressure transmitter and

alarm, is specifically

designed for flow display on

Flo-Bar installations. This

provides 4-20mA and

totaliser pulse outputs.

Ask for Data Sheet DS 1720.

Flow DP Gauge

Differential pressure

indicators can be installed

to monitor the Flo-Bar

generated DP, giving a

simple visual indication of

flow rate.

INSTALLATION INFORMATION

The installation of a Flo-Bar is straightforward, but must follow the normal rules stated for Orifice Plate or similar DP devices in BS EN ISO

5167. In general this means siting the Averaging Pitot Tube at least 7 diameters downstream of a single bend, and 3 diameters upstream

of a similar obstruction.

On horizontal pipes, the positioning of the Pitot Tube must not allow condensation in gas flow lines, or air bubbles in liquid flows, to col

lect in the head. So for gas flow measurement, for example, the Flo-Bar head must be above the pipeline, to allow any liquids to drain

away.

Flo Bar units can be installed in horizontal, vertical or angled pipelines: the position across the pipe diameter and the alignment of the

pressure ports must be maintained within 3o for the quoted accuracy to be achieved.

More information is provided in the Flo-Bar operation and maintenance manual (OMM1035), available on request.
