Krohne, German manufacturer and global supplier of process instrumentation, presents the ultra-compact AF-E 400 electromagnetic flowmeter, specially designed for applications in confined spaces.
In particular, it can be placed on welding equipment cooling lines, on bending machines and robots, or on chemical dosing skids, and meets the requirements of heating and cooling applications, washing or dosing machine construction, HVAC applications, as well as utilities and industrial automation, in all process industries.
"After analyzing the limitations of this segment, Krohne developed this ultra-compact economy flowmeter to be the best in its class in terms of temperature range, accuracy, pressure drop and flow scale."the company says.
The AF-E 400 features a stainless steel housing and is suitable for liquids up to +90°C, enabling it to be used continuously on highly demanding heating and cooling water applications.
The reduction of the round probe bore makes the flowmeter more resistant to pressure and offers high accuracy over a wide pressure and temperature range.
What's more, it offers a high flow ratio without the risk of cavitation. Integrated temperature measurement eliminates the need for an additional probe, minimizing the need for pipe tapping and enabling more process data to be obtained.
The AF-E 400 also features comprehensive self-diagnostic functions: the flowmeter continuously monitors a number of critical aspects, including a drop in supply voltage, incorrect parameter settings, flow overshoots or short-circuits on any of the outputs. Warning messages according to Namur NE107 alert the user via the rotating color display or communication outputs.
Thanks to the special design of its magnetic circuit, the strength of its magnetic field and its electronics, the AF-E 400 is insensitive to parasitic coupling caused by superimposed magnetic fields from nearby devices. It can be installed in series or in parallel, up to a distance of 2 mm from another instrument, without interference.
Nominal probe sizes range from DN6 to DN25 for flows up to 150 l/min as standard, and up to 500 l/min on request. Output options of 4...20 mA, pulse, frequency, threshold, IO-Link or Modbus, provide operators with a wealth of measurement and application data, for "smarter" plant automation. The AF-E 400 is shipped within 48 hours.
