Metal Tube Type Variable Area Flowmeter AM9000 Series

The AM9000 series metal tube variable area flowmeters have the unified face-to-face dimension 250mm.
Having developed the current well-accepted AM7000 series, the AM9000 has a compact and unified construction which makes piping design simpler and saves installation space, leading to a low engineering cost.
In addition to highly reliable mechanical local indicator, a variety of standard-equipped functions such as electric transmission, local flow integration and integrated flow transmission by pulse, alarm, and digital communication of these data can meet your various requirements.
The AM9000 covers liquid, gas and steam measurement in various fields.
Full line-up to meet all possible requirements !!

All the necessary functions required for variable area flowmeter, local indication, electric transmitters, local flow integration, PROFIBUS PA & HART communication, integrator with scaled pulse output and alarm are now available from one line.

Compact design

Smaller and lighter…To suit modern needs.
Unified face-to-face dimension 250 mm makes piping design easier.

Wide pressure range

150 lbs and 300 lbs rating are available as standard and higher pressure versions are also available as option.
