3�2 Setting Options; Functions And Features; 4�1 Pressure Equipment Directive (Ped); 4�2 Applications - KROHNE AF-E 400 Handbook

3.2 Setting options
• Output functions of OUT1 and OUT2 (temperature or volumetric flow;
switching, pulse, frequency, analogue signal, totaliser function)
• Reversal of the volumetric flow direction, monitoring of the volumetric flow
• Response times for volumetric flow measurement (measured value damping,
start-up delay, low flow cut-off)
• Error behaviour of the outputs
• Standard views of the display (unit of measurement, process values, quantity
meter, refresh rate, rotation, brightness, process value-dependent change of
the colour of the characters)

4 Functions and features

The unit monitors liquid media� It detects flow velocity, volume flow (volumetric
flow quantity/time), consumed quantity and medium temperature�
4.1 Pressure Equipment Directive (PED)
The units comply with the Pressure Equipment Directive and are designed and
manufactured for group 2 fluids according to the sound engineering practice�
Use of group 1 fluids on request�
4.2 Applications
