Does anyone know why Europa HQ have not been answering the phone for the last two weeks?

By proper differential pressure I assume you meant on one side there
will be the fluid pressure, and on the other side there will be tank
air pressure. I gathered from Paul's email that he did exactly this by
running the tank vent line to the sensor, but still sees a lag during
climbs and descents. This is most likely due to the large tank volume
and the small diameter of the vent tube. So it would matter exactly
where the vent line is teed off to go to the sensor. Closer to the
tank is better. In any case, this delay is likely to be
inconsequential because most of the spam cans I fly are only required
to have a reliable level indicator when the tank is really empty.

Hi David
Karen is away on holiday, she is back to work on Monday 2nd December.
I believe if it was urgent people could phone the aircraft team in norwich on [url=tel:01603%20262301]tel:01603262301[/url]
Was advertised on europa webpage and in any email correspondence that came from Karen.
Kind regards
Donald

Thanks Donald, I will have a look in my loft when I get home, I think I have an old answering machine that you can record a message on, and send it to Mr Swift. It would be a pleasure to give something back to the mothership
