Calibration #7: Calibrating the nCG Flow Meter
1. Disconnect the expansion coil from the bottom of the NCG burette. To avoid damaging the expansion coil Loosen
bottom nut on expansion coil and remove top nut.—use two wrenches 10mm and 11mm to
ensure
no
damage to the NCG burette occurs—and swing out of the way.
2. Place the 1 liter draw vessel filled with tap water on top of the Steam QM-3 so as to have good gravity flow.
3. Connect the 6mm tube coming from the 1 liter draw vessel to the bottom of the NCG burette (where the expansion.
coil was connected—use two wrenches 10mm and 11mm to ensure no damage to the NCG burette occurs).
4. Disconnect the 6mm tube coming from P1 where it connects to the top of the NCG burette.
5. Connect the NCG injector assembly tee to the top of NCG burette.
6. Connect the 6mm tube that was disconnected from the top of the NCG burette to the top of injector tee.
7. To avoid damage to P1 by creating a vacuum, always remove the NCG injector syringe before resetting
to
2ml.
8. With the NCG injector syringe disconnected, reset the syringe to 2ml.
9. Connect the NCG injector syringe to the middle of the NCG injector assembly tee with a 6mm tube.
10. Force open the EV1 valve using the pressure calibration menu 152.
11. On the Steam QM-3 display pad, press left and right arrows simultaneously to access the code menu.
12. To access the pressure calibration menu, enter code 152 using the up and down arrows to change numbers, and the
left and right arrows to change the position.

13. To force open the EV1 valve to allow discharge move the arrow to the EV1 line then move the arrow to left of 1 and
press OK.
14. Open the valve on the 1 liter draw vessel to fill NCG burette and allow water to run into the waste container.
15. Close the valve on the 1 litter draw vessel.
16. Close the EV1 valve using menu 152 on the control panel, move the arrow to left of 0 and press OK.
17. To avoid damage to P1 by creating a vacuum, always remove the NCG injector syringe before resetting to 2ml.
