Direct routing of sample lines is also recommended.
If the large process pipes are horizontal, taps should be in-
serted vertically in the middle of the pipe to avoid pulling
sediment from the bottom or air bubbles from the top of
the pipe into the sample line.
A 1/2” BSP sample input fitting allows direct connection to
the optional input filter.
Sample line pressure should be between 0.07 and 4 bar (1
and 57.2 psig) with an ideal pressure of 0.7 bar (10 psig).
Drain Line Installation
The drain hose fitting is a 20 mm (3/4”) hose barb on the
bottom of the instrument enclosure. An air gap between the
end of the drain hose and the drain is recommended to prevent
any back flow into the instrument in the event of drain block-
age.
