Krohne AF-E 400 compact electromagnetic flowmeter

Monday, 13 September, 2021 | Supplied by: KROHNE Australia Pty Ltd


Krohne has introduced the AF-E 400 ultracompact electromagnetic flowmeter for utilities and industrial automation applications. It is designed to fit in applications with little installation space available, such as in cooling lines of welding equipment, bending machines and robots, or on chemical dosing skids.

The product features a stainless steel housing and is suitable for continuous use at 90°C liquid temperature, allowing for operation in demanding cooling and hot water applications. The round bore reduction of the sensor makes the flowmeter resilient in terms of increased pressure, which should enable high accuracy over a wide pressure and temperature range and a high turndown ratio without risk of cavitation. The integrated temperature measurement eliminates the need for an additional sensor.

With built-in self-diagnostics, the meter continuously monitors several critical aspects including low supply voltage, incorrect parameterisation, flow range exceedance or short circuit on any of its outputs. Warning messages according to NAMUR NE107 alert the user via the rotatable full-colour display or the communication outputs.

Due to the special design of its magnetic circuit, field strength and electronics, the unit is immune to crosstalk caused by magnetic field overlap with adjacent devices, and can be installed in series or in parallel up to a distance of 2 mm from device to device without interference.

The product supports flow rates up to 150 L/min as standard and up to 500 L/min on request. Output options include 4-20 mA, pulse, frequency, switch, IO-link or Modbus.
