Do you have any length of hose attached to the output port of the meter?

It's about a foot maybe a bit less. The fact that the reading is
very repeatable ( meter same quantity into each wing and glider
balances) suggests to me that the metering vane is always fully
immersed in the flow. If that is the case then why would the output
hose length matter?
