Abstract

Optical fiber interference target flowmeter. In this paper theories of the flowmeter and its damper are demonstrated, the structure of the damper is given. Experiments have been done to study the relationship between damping index and clearance, relationship between clearance and viscosity under a fix damping index, relationship between damping index and viscosity under three kinds of clearance. The experimental results showed that the designed damping system could slow down deformation speed of a cantilever used in flowmeter and, furthermore, slow down the drifting speed of interference fringes. This will cut down cost of the interference flowmeter.
