OUTLINE

The AM3000 series micro flowmeter is a metal tube flowmeter

for small flow measurement. The all-metal construction ensures

precise measurement even in high-temperature and high-pressure

services.

Thanks to its compact design, the AM3000 is suitable for assembling

onto various devices. It can also be used for small-bore industrial

processes.

As outputs, current output and current output with HARTR

communication are available.

Local indication, pneumatic output, and alarm output functions

are available in the M-900 series.

AM3000 Series

MICRO FLOWMETER

OPERATING PRINCIPLE

The flow path has a tapered part. A float containing a magnet is

located in the tapered tube. Fluid flows from the bottom of the

flowmeter and goes upward through the tube. The differential

pressure produced by the float and the tapered tube pushes the

float upward, and the float stops when the weight of the float

and the differential pressure balance. In other words, the position

of the float corresponds to the flow rate. The movement of the

magnet in the float is detected by the magnetic coupling, which

converts it into the movement of the pointer.
