DP Flometer Works but Unstable

I note that this is a continuation of a previous thead,

http://cr4.globalspec.com/thread/102442/DP-Flowmeter-Works-Unstable

with zero feedback from the OP, which is usually a red flag to not bother, but I'm feeling charitable today so I'll give it one more spin.

1) Are there two condensate/seal pots hidden under the insulation, about where the arrow is located?

2) Are the condensate/seal pots higher in elevation in than the pipes taps, similar to the respective elevations of the condensate pot and taps in this diagram?

3) Condensate/seal pots need to drop the temperature of the steam and allow it to condense to water, that's their purpose. Insulating them keeps the condensate (under pressure) nearer its flash point temperature. Why are the condensate/seal pots insulated?

4) Why do you say, "too much water come out from Trinsmitter" when you drain the impulse line? How much is too much? 3cc's? 800L?

5) > "its reading is rising then becomes zero at last Negative"

Please provide examples: the values, the numbers as they rise, then become zero then negative and over what period time?Is there a trend chart from the DCS that shows this ? What criteria are you using for the correct amount of water?

Is the decline from some rising maximum to zero a straight drop to zero?

6) Out of curiosity, are there root valves at the taps?
