When the instrument go through the insulating tube (φ62), the centralizer and collecting umbrella are closed. Centralizer controls collecting umbrella open. When the instrument reaches the test section – oil layer casing (φ160), the centralizer is open, as well as collecting umbrella.The fluid is forced to flow into flowmeter under the control of collecting umbrella, then the high-temperature steam entirely adhere to the meter,which improves steam flow measurement accuracy.

Structure:centralizer +collecting umbrella + turbine flowmeter

5-10 times higher resolution of steam absorption cross section
