Krohne, a German manufacturer and global supplier of process instrumentation, presents the AF-E 400 ultra-compact electromagnetic flow meter, specially designed for applications in tight spaces.
It can be placed on the cooling lines of welding equipment, on folding machines and robots or on chemical dosing skids, and meets the requirements of heating and cooling applications, construction of washing or dosing machines, CVC applications, as well as utilities and industrial automation. , in all process industries.
"After analyzing the limitations of this segment, Krohne has developed this ultra-compact economic flow meter to be the best in its class in terms of temperature range, accuracy, load loss and flow scale,"the company said.
The AF-E 400 features a stainless steel case and is suitable for liquids up to a temperature of 90 degrees Celsius, allowing it to be used continuously on very demanding heating and cooling water applications.
Reducing the probe's round bore makes the flow meter more resistant in terms of pressure hold and provides high accuracy over a wide range of pressure and temperature.
In addition, it has a high flow ratio without the risk of cavitation. The built-in temperature measurement eliminates the need for an additional probe, minimizing stitching on the pipes and allowing for more data from the process.
The AF-E 400 also has complete self-diagnosis features: the flow meter continuously monitors several critical aspects, including a drop in power voltage, incorrect settings, flow scale overruns or short circuits on one of the exits. Namur NE107 warning messages alert the user via the rotating color display or communication outlets.
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 couplings caused by the overlays of magnetic fields of nearby devices. It can be installed in series or in parallel, up to a distance of 2 mm from another instrument, without interference.
The rated sensor sizes range from DN6 to DN25 for speeds of up to 150 l/min as standard and up to 500 l/min on demand. Exit options 4... 20 mA, pulses, frequency, threshold, IO-Link or Modbus, provide operators with a lot of measurement and application data, for a more "smart" factory automation. The AF-E 400 is dispatched within 48 hours.
