1. What type of interface is marked with SWG on the flowmeter?
The SWG interface marked on the flowmeter is a sleeve type fluid connection interface with dimensions defined by the Standard Wire Gauge (SWG) in the United States, used to adapt to fluid transport pipes of corresponding wire gauge specifications.
1. Core Definition and Source 1 SWG was originally a standard system used in the United States to standardize metal wire, pipe diameter, and wall thickness. Nowadays, it is directly used in the field of fluid connections to label pipe specifications that are compatible with interfaces. The most commonly used type of interface is the double trap clamp type connection structure, which achieves leak free sealing by locking the pipe. It is one of the common interface forms for industrial instruments such as flow meters and pressure gauges.
II. Common Application Scenarios 1 This type of equipment is commonly found in high-precision laboratory flow meters and small industrial process flow meters. These devices require pipes that are compatible with globally recognized specifications, and the SWG standard has strong universality. In some technical documents, interfaces marked with SWG are also directly referred to as "SWG sleeve interfaces" to distinguish between metric (mm), Wanglingbi British BSP threaded interfaces, and other types of instrument interfaces.
III. Selection Precautions 1 It is necessary to clarify the actual pipe parameters corresponding to the SWG number, for example, the outer diameter of the stainless steel pipe corresponding to SWG 10 is about 3.41mm, and the wall thickness is 0.46mm, to avoid mixing with metric pipe sizes. 2. It is necessary to match the pressure and
