Product Description
Krohne H250 M40 Metal Variable Area Flowmeter

The H250 M40 is the standard variable area (VA) flowmeter for the process and OEM industry. This device combines mechanical flow measurement of liquids or gases with state-of-the-art communication capabilities. Its modular design allows for electronic modules to be added or replaced at any time without process interruption.

The sturdy all-metal flowmeter is engineered for applications with high pressures (up to 1000 barg / 14500 psig), extreme temperatures (-196 to +400°C), or aggressive media. It supports installation in horizontal or descending pipes and is intrinsically safe and explosion-proof.

Key Features
Simple, low-cost installation without auxiliary power.
Modular scalability from mechanical to fieldbus.
Universal Ex concept: Exi, Exec, Exd and Ext.
Suitable for safety-related SIL2 applications.
CFM application diagnostics for float blocks and pulsation.
Any installation position: vertical upward, horizontal, vertical downward.
