Attention :
When reading the diagram, operating cubic meters must be applied. The
pressure loss as read must be multiplied with the absolute pressure in bar
(excess pressure +1). This is to take the density fluctuations in to considerations.
THE PRESSURE DROP MUST NOT EXCEED 10 mbar. |
|
Example :
Excess Gas Rresssure: 4 bar , Operating Flow Rate 150 M³/hr of Natural Gas.
Filter chosen from the diagram : DN 65, the pressure drop read is 1.5 mbar. REAL PRESSURE DROP : 5 X 1.5 mbar =7.5 mbar. The real pressure drop is less than 10 millibar, therefore, correct size filter has been chosen. |
