Inert Gas Supply Valve Configuration Option 1
Filling the inert gas supply tank with inert gas supply tank isolation valve C open also pre-charges the LS-14.
Figure 11: Inert Gas Supply Valve Configuration Option 1
17.
Connect an appropriate customer-supplied nitrogen or other inert gas supply container to inert gas supply tank fill valve
B located between the valve on the inert gas supply tank (valve A) and the isolation valve (valve C) (
Figure 11 ).
18.
Open valves A and C, and then slowly open valve B ( Figure 11 ).
19.
Allow the inert gas supply tank to fill.
20.
While filling the inert gas supply tank, refer to the pre-charge side pressure gauge to monitor the pressure of the tank
(
Figure 4 ).
21.
If the product side pressure gauge shows pressure, open purge/return valve D to lower the piston and relieve pressure
within the LS-14 (
Figure 4 ).
22.
Fill the inert gas supply tank until the pre-charge side pressure gauge reads 50–100 psig above pipeline operating
pressure, not to exceed the maximum allowable operating pressure of the LS-14.
23.
Once full, close valve B and disconnect the customer-supplied inert gas supply container. Valves A and C must remain
open (
Figure 11 ).
24.
Plug the port of valve B by wrapping the threads of a male hex plug with PTFE tape and screwing it into the port of
valve B (
Figure 11 ). Valve B must remain plugged at all times except when adding inert gas to the inert gas supply tank.
25.
Check all connections between the inert gas supply tank and the receiver cylinder for leaks. Repair as necessary.
26.
If the LS-14 will use pneumatics for mixer actuation, proceed to step 37. If the LS-14 will use hydraulics for mixer
actuation, proceed to
Section 2.3, Preparing for Sampling .
