GAS Tubing
Reference Figure 13 for the instructions below.
1. Cut a 3-4” piece of 3/16 inch tubing for each GAS fitting on every SDM-2009
except the last one.
2. Connect the tubing to the GAS fitting on every SDM-2009 except the last one.
3. Insert the smaller T-fittings into the tubing so that the remaining two ports on
the T-fitting are perpendicular to the GAS fitting.
4. Cut 6-7” pieces of 3/16 inch tubing and connect the T-fittings.
5. Cut one more 6-7” piece of 3/16 inch tubing and connect the GAS fitting of the
last SDM-2009 to the T-fitting from the second to last SDM-2009.
6. Cut 1 piece of 3/16 inch tubing long enough for easy access to the calibration
cylinder and connect it to the T-fitting on the first SDM-2009.
