Underground Drain Tank - Annular Pressure Measurement

01/05/2009 1:06 PM

1)Ref to attached file for tank no 10 ,with PIT1010 used for Measuring annular presure

between inside & outside tank (double wall ) may i know is dis scheme feasiable

since the vessel is exposed to atmospheric pressure so the pressure will always be greater than 5-10 psig ( 14.7 )and we will always have alarm

note : assuming pressure xr is used for leakge ( rupture of the inside vessel )

Hi josej,

Can you make another, clearer drawing. The picture is blurred and the prints are too small to read. A screen shot is not recommended for such small detail.

regards,

Vulcan
