OUTLINE

M-900 series MICRO FLOWMETER is a metal tube

variable area flowmeter for small flow measurement.

All metallic construction covers even high temperature

and high pressure applications.

Thanks to compact design, M-900 is suitable for

assembling onto various devices. It also covers small

sized industrial processes.

M-900 series MICRO FLOWMETER has been used for

nuclear power plants for long time and HPGSL certified

version is also available.

In addition to local indication, alarm output and

pneumatic transmission types are ready to meet your

requirements of remote monitoring and control.

industrial processes

M-900 Series

MICRO FLOWMETER

OPERATING PRINCIPLE

The flow path has a tapered part. A float in which a

magnet is moulded is located in the tapered tube. The

fluid is introduced from the bottom end of flowmeter

and goes through the tube upward.

Because of the differential pressure produced by the

float and tapered tube, the float is pushed upward

and stops at a position where the weight of float and

the differential pressure balance. Thus, the position

of float corresponds to the flow rate. The moulded

magnet in the float attracts the pointer, and the pointer

indicates the flow rate on the scale plate.

The inside of the tube and indication mechanism are

totally isolated by magnetic coupling.
