Collector at 200°F before I removed the flowmeter. The leak at the flow meter after purging yeaterday has not created a problem yet. Why is temperature so high? Well.... Flow is OK, 1.

Water Propylene Glycol was leaking out of the glass to brass area. If I pushed on the glass with my finger the leak would increase.
