*Specifications are subject to change without prior notice.

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.

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!
