I assume that element.Next() is blocking on one of the subscriptions.
You could retrieve deliveries from each subscription with a timeout to
read past it. Alternatively you could set up a single queue to receive
all measurements and retrieve messages from it with a single subscription.

The best setup will depend on how frequently measurements are expected,
whether they are correlated, whether other consumers also need to
observe them, and so on. A list of subscriptions is probably not ideal
in most cases.
