KROHNE Cologne Rotameter H250 Metal Tube Float
The H 250 is a modular metal tube rotameter with an all-metal structure, with no magnetic hysteresis, no transmission mechanism, and field-installable gas damping device. Based on modular design, remote signal output, switch signal output, cumulative amount display, HART protocol execution, Profibus-PA bus, all can be installed and used immediately according to user needs. High temperature and high pressure design, selection of anti-corrosion materials, and X-ray flaw detection can ensure that the product is suitable for any field needs. According to the measurement environment, it can be installed vertically or horizontally, and can be connected by flange or screw.
The production and application experience since 1990 provides you with the perfect service. H250 has been widely used in the measurement and process control of liquid, gas and steam media in petroleum, chemical, metallurgy, electric power, food, pharmaceutical, paper and other industries
