VA20S Glass rotameter compared with the other domestic products of the same type, it has advantages of
high measuring precision, good interchangeability, multiple connection ways, especially the value of flow
rate of the flowmeter is in millimeter scale mark, which is capable of providing actual flow scale according
to the temperature, pressure, density, and viscosity of different flows, solving the problem of indication
correction. As for the ways of connection, use pipe threaded connection.
