The Flowtech VA20s series of glass tube rotameter is an integrated product by glass tube, SS304 float with SS304 thread connection. It has an advantage of high measuring precision, good interchangeability, wide measuring range especially the scale mark in milimeter. It is capable of providing actual flow scale according to temperature, pressure, density and viscosity of different flows, solving the problem of indication correction.
