    摘要: A pressure sensing chamber having a tubing extension with a reduced diameter portion extending through the chamber. The tubing contains a plurality of ports so as to allow the purging of air from the chamber, but the ports are sized so that bubbles entering the tubing cannot easily flow into the chamber. The reduced diameter portion creates a pressure differential between the holes. This differential pressure creates flow through the chamber under high liquid flow and turbulent liquid flow events.
