Flowmeter > M-900 Series





M-900 is a series of Metal Tube Variable Area Flowmeters designed for small flow.
M-900 covers high temperature and pressure applications which are not acceptable glass tube Purgemeter.
In addition to local flow rate indication by a scale and a pointer, alarm contact or electric analog output is available.
For low pressure gas, less than 0.29 MPa, a damper can be equipped with.


Full line-up to cover possible requirements
Indication, alarm as well as analog output!

Compact Design
Suitable for panel mount. Also suitable for small size process lines!

Suitable for High temperature and pressure
Safety due to metal tube construction

Wide material selection
Besides standard stainless steel version, special metallic material such as MA276, Titanium are available.

Recommended Applications

· Small size industrial process lines
· Assembling onto Analyzers and other devices
· High press. purging
· Others
