Hi Marc,

Ok, I think we are good to do the test now.

Hi Marc,

I’m not sure if we can run today. I am not used to changing the regulator so I was trying to coordinate with Chuck. I’ll let you know.

Hi Holly,

Here is a formalized plan for the test. I have verified that all pressure and flow monitoring is up and running.

Regards,
Marc

Hi Holly,

Lets make the pressure range from 0 to 8 psi. I just verified that the regulator output pressure is 8 psi.

Marc

Hi Holly,



The logging is back online. Tomorrow is fine, can you email me before you start the test so I can verify the WEDM/MYA is working before you start.

Hi Marc,



Sounds good-just let me know when you are ready. We could do this tomorrow.

Hi Holly,



I need to coordinate a test with your group. I need to get data on the flow as we change the pressure regulator from 0 to 9 psi in steps. This will help with the development of the overpressure protection setup using the mineral oil bubblers Brad provided.



I am waiting for the network folks to fix an issue with WEDM and MYA, hopefully that will be fixed soon and we can set up  the test.



Basically I need to lower the pressure regulator to 0, record the baseline flow, then change the regulator to 1 psi for a minute, then 2 psi for a minute...all the way to the current setting of 9 psi.



I'll email you when the logging is back online so we can set it up.



Regards,

Marc
