GFM84 series intelligent LCD metal tube rotor flowmeter

GFM84 series intelligent LCD metal tube rotor flowmeter

Overview

GFM84系列Intelligent metal tube float flowmeter is a commonly used variable area flow measurement instrument in industrial automation detection processes. It has the characteristics of small size, large detection range, and easy use, and can be used to measure the flow rate of liquids, gases, and vapors. Caliber fromDN15～DN200, accuracy1.5Grade, particularly suitable for flow measurement of low flow rate and small flow rate media, as well as flow measurement of high temperature, high pressure media, opaque and corrosive media.

application

For many years, metal tube float flowmeters have been widely used for flow measurement of liquid, gas, and steam media in industries such as petrochemicals, steel, electricity, metallurgy, light industry, food, pharmaceuticals, and water treatment due to their excellent performance and good cost-effectiveness.
