THE BON•O•METER CONCEPT |
 |
The concept of the measurement comes from the |
| |
Bernoulli theorem/principle, commonly used for the
Dp metering flange engineering. ISO 5167 is the
international standard that technically specifies the
application. In a few words a calibrated orifice
assembled in a pipe reduces locally the pressure
of the fluid in such a manner that the local delta
pressure imposed by the orifice, opportunely measured
by means of Dp devices, is related to the
capacity of the fluid flow that passes throughout
the orifice itself. The orifice is integrated in the ball,
so that the ball and the orifice are one piece only. |

THE BON•O•METER ADVANTAGES |
|
The BON•O•METER may be installed as a normal on-off ball valve. |
| |
In case it is required the BON•O•METER gives the chance to collect the relevant process data
(capacity flow, density, temperature, static pressure…) by means of a secondary transmitter
that can be connected with the automatic connections of the valve. |
|
The BON•O•METER gives the chance to perform the process measurement on the valve, |
| |
avoiding the use of other primary metering devices, such as Dp flange, nozzle, Venturi nozzles.
The advantages are: |
|
To save money for the reduction of the number of components in comparison to a standard application |
| |
(Dp flange, pipe length, thermometer well). |
|
To reduce the costs of installation. |
|
To reduce the overall dimensions of the application in comparison with a standard application |
| |
(valve, pipe, thermometer well). |
|
To save money and time by means of the easy interchangeability of the ball/orifice. |

TOPAZ BALL VALVE |
|
TOPAZ ball valve in stainless steel, of solld and advanced design, is backed |
| |
by the twenty-year experience gained by ENOLGAS in production of ball valves. |
|
In order to keep tolerances and material quality constant, investment casting of body and end adapter |
| |
was preferred to forging, with careful subsequent toolings on CNC machines,
which guarantees a high quality standard. |
|
Leading design and accurate machining and finishing of the valves guarantee a perfect tightness |
| |
and lifetime troubleless working operations. |
