Description

Metal tube rotameter with stable structure

Technical Field

The utility model relates to the technical field of rotameters, in particular to a metal tube rotameter with a stable structure.

Background

Rotameters measure fluid flow according to the throttling principle, but they change the flow area of the fluid to keep the differential pressure across the rotor constant, so are also known as variable flow area constant differential pressure meters, also known as float meters.

In actual measurement, customers often reflect that the instrument is blocked, the reasons are many, most of the reasons are flow impact through investigation, the valve opening is too large, the impact is likely to cause blocking or component damage, the instrument cannot be measured normally, the service life of the instrument is influenced, normal production work is achieved, and the traditional damping system can reduce the impact but has limited release degree and cannot meet the field requirement. In view of this, we propose a metal tube rotameter having a stable structure.
