Product Introduction

💡

H250 M40 Rotameter: The standard variable area (VA) flowmeter for the process and OEM industry. It combines mechanical flow measurement of liquids or gases with state-of-the-art communication capabilities. The device is modularly extendable, allowing modules to be added or replaced without process interruption.

The sturdy all-metal flowmeter can be used in applications with high pressures (up to 1000 barg), extreme temperatures (-196 to +400°C), or aggressive media. It allows installation in horizontal or descending pipes up to DN150. Special hygienic versions are also available. The H250 M40 is intrinsically safe and explosion-proof.
