Flowmeter > MA-900 Series




MA-900 is a metal tube variable area flowmeter designed for the measurement of small flow of liquids and gases. MA-900 covers tough applications with high pressure and temperature which are not suitable for glass tube purgemeters. In addition to local indication version, an alarm output option is available.


Very small flow rate can be covered
Min. 0 - 0.5 L/h [Water] can be measured.

Alarm output option available
In addition to local indication type, alarm output version is also available.

Compact design
Easy installation onto instrument panel!

Safety for high temperature and pressure
All metallic material construction covers tough applications!
