3.1.4 Connecting the external sample lines
To make external sample inlet connections:
1. Fit a shut-off valve (not supplied) at each sample inlet.
Referring to Fig. 3.4:
2. Connect sample inlet tubing as follows:
a. For
multi-stream
wet-sections
without flowmeters
, connect
1
/
4
in. ID (or equivalent) plastic tubing (1 tube per stream) to
barbed connectors
A
.
b. For
multi-stream
wet-sections
with flowmeters
, connect
3
/
8
in. ID (or equivalent) plastic tubing (1 per stream) to spigot on
flowmeters
B
.
c. For
single-stream
wet-sections
without flowmeter
, connect
1
/
4
in. ID (or equivalent) plastic tubing to barbed connector
C
.
d. For
single-stream
wet-sections
with flowmeter
, connect
3
/
8
in. ID (or equivalent) plastic tubing to spigot on flowmeter
D
.
3. Ensure the wet-section internal sample stream drain tubing and sample outlet tube is routed through the drain outlets at the
base of the wet-section and through the funnel
E
– refer to Fig. 8.5, page 65 (multi-stream) or Fig. 8.7, page 67
(single-stream) for tubing location details at the base of the wet-section enclosure.
4. Connect the flowcell drain tubing (customer-supplied) to the barbed connector at the base of the wet-section
F
.
Note.
Sample inlet tubing to the base of the wet-section is customer-supplied.
Sample inlet tubing must have sufficient wall thickness to withstand the highest sample pressure. Keep tubing lengths
short.
Keep sample drains as short as possible and vertical to enable the sample to drain freely.
Where particulate matter is present (for example, magnetite in boiler samples) it is recommended that a 60 micron sample
filter is fitted to the sample inlet line.
