Kaidi KD FVA Metal Tube Float Flow Meter Exia II CT4 for electric power
F V A metal tube float flow meter adopts variable area measurement principle. It has the characteristics of solid and reliable structure, wide temperature range, high precision, low price, and can be used for flow measurement in a variety of occasions. It can be widely used for liquid and gas flow measurement in national defense, chemical industry, petroleum, metallurgy, electric power, environmental protection, medicine and light industry.
①Suitable for small pipe diameter and low flow rate
②The requirements for the downstream straight pipe section are not high
③There is a wide flow range of 10:1
④The intelligent indicator has LCD liquid crystal display, which can display instantaneous and cumulative flow, and can also output pulses and output alarms.
⑤There are various forms such as in-situ type, remote transmission type, jacket type, explosion-proof, corrosion-resistant, etc.
