Tokyo Keiso MA-900 Micro Flowmeter

Made in Japan

Manufacturer: Tokyo Keiso

Model: MA-900

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 purge meters. In addition to local indication version, an alarm output option is available.

Features

  • 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!
