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.
