HFVAMT METAL ROTOR FLOWMETER

Writer： admin Time：2021-03-08 18:26 Browse： ℃

1. Introduction:
HFVAMT metal rotor flowmeters are rugged and durable, with an accuracy of 0F 1% for all metal flowmeters. The HFVAMT is made of stainless steel and is used to measure various gases and liquids. HFVAMT can be configured with a variety of linings for corrosive liquid and gas applications. The flow indication is provided by magnetic coupling in which a magnet encapsulated in a float is coupled to a rotatable magnet located at the rear of the indicator to turn the dial indicator mounted on the meter. Optional accessories include 4-20 mA output with HART microprocessor transmitter, with or without alarm and pulse output for tantalization. A variety of mechanical counters are also available.
