Description

Technical Field

[0001] The utility model relates to the technical field of air pressure measurement, in particular to a flow stabilizer used for air pressure measurement. Background Art

[0002] In the field of central air conditioning, to measure the pressure of the measured space, the other end of a transparent hose connected to a pressure measuring instrument is typically inserted directly into the cabinet panel, or a pipe connector is used to connect the pressure for measurement. When the airflow in the measured space fluctuates, especially when the airflow is highly turbulent, the large inner diameter of the transparent hose or pipe connector will cause the instrument reading to have a wide range and inaccurate readings. This will affect the frequency of component replacement (such as air filters) and result in wasteful resources. Therefore, we propose a flow stabilizer for air pressure measurement.
