NOTE
Mass Flow Meter
Removing the mass flow meter
1. Remove the top cover from the analyzer.
2. Remove the cover for the oven assembly. Facing the front of the
Model 3050-RM analyzer, the mass flow meter is the small black box
on the left-hand side of the sample oven (Figure 8-2).
3. Disconnect the 1/16 inch fittings on all four sample tubes, which are
located on the bracket in the center of the sample oven (Figure 8-1).
4. Remove the four nuts that secure the sample manifold plate (the
square aluminum mounting plate, located in the front section of the
oven), and gently lift the manifold out of the oven.
All of the wiring connections should still be intact at this time; you
will need to rest the sample manifold plate on top of the analyzer to
remove the flow meter.
5. Disconnect the cable from the flowmeter (Figure 8-4).
6. Disconnect the 1/16 inch tubing connections at both ends of the flow
meter (Figure 8-4).
7. From the bottom side of the sample manifold plate, remove the screws
securing the flowmeter (Figure 8-4). Remove the old flow meter, and
set it aside.
Installing the mass flow meter
1. Attach the new flow meter to the sample manifold plate.
2. Reconnect the 1/16 inch fittings to the inlet and outlet of the new flow
meter.
3. Reconnect the cable to the flow meter.
4. Place the sample manifold plate back in the oven and secure with the
four mounting screws.
