4 How to Tube
- 16 -
(6) Determine the inlet for the sample gas, considering the airflow of the sample gas line and the gas
generating process. Also, avoid collecting a gas from the pipe, tank and the bottom of the device.
(7) As a general rule, exhaust should be atmosphere release. When the tip is outside, bend the shape of
the tube into an inverted U to prevent rain from entering the tube. When it returns to the exhaust duct
etc., keep the state within the atmosphere pressure of
±
3 kPa, and the state that pressure fluctuation
is not rapidly changed.
(8) For safety, to provide a flame arrestor for line, install it into each line of the GAS IN and GAS OUT.
CAUTION
FI-815A requires appropriate tubing works (selection of materials and other works) depending on
types of sample gas and installation conditions. For questions about tubing works, please contact
RIKEN KEIKI.
