Instalatpo de annubar

(OP)
E possibel instalar um annubar para liquidos na parte superior da linha de processo. O erro acrescentado e tolerável?

RE: Instalatpo de annubar


Google translate:

"And Annubars possibel to install a liquid at the top of the process line. The error added and tolerable?"

Better to install at the bottom as advised by the manufacture, to avoid uncertainties.

or by Google:

Melhor para instalar na parte inferior como recomendado pelo fabricante, para evitar qualquer dúvida.

Voids
Air or gas entrapped in liquid-sensing lines can cause false pressure readings, sluggish response, and extraneous noise as a result of acoustic resonances. For example, in differential-pressure measurements, an air pocket on the low-pressure side can cause the pressure indication to be higher than normal. It can also add a delay in the transmission of the pressure information. Purging air from voids is difficult. Though one would expect air pockets to dissolve in the liquid under the high pressures common in industrial pressure measurements, the problem of voids persists.

RE: Instalatpo de annubar

It is possible to modify a pitot tube so it can be installed from the top.

Entrained air will travel upwards, if the sensing ports go down first then up air will not enter.

Of course this is not an off the shelf solution.
