Functions And Features; Function; 4�1 Processing Of The Measured Signals; 4�2 Volumetric Flow Monitoring - IFM Electronic efector 300 SU9004 Operating Instructions Manual

3 Functions and features
The unit monitors liquids�
It detects the 2 process categories volumetric flow and medium temperature�
Applications:
• Water
• Glycol solutions
• Oils (viscosity: ≤ 68 mm²/s at 40°C)
Selection of the medium to be monitored → 9�4�8�
4 Function
4.1 Processing of the measured signals
• The unit displays the current process values�
• It generates 2 output signals according to the parameter setting�
- OUT1: analogue signal for temperature�
- OUT2: analogue signal for volumetric flow�
4.2 Volumetric flow monitoring
The flow rate is monitored by an ultrasonic meter, the measured signals by the
electronics�
• An analogue signal proportional to the volumetric flow (4���20 mA) is provided
on output 2� For the analogue functions → 4�4�
4.3 Monitoring of temperatures
• An analogue signal proportional to the temperature (4���20 mA) is provided on
output 1� For the analogue functions → 4�4�
4.4 Volumetric flow or temperature monitoring / analogue

function

• The analogue start point [ASP] determines at which measured value the output
signal is 4 mA�
• The analogue end point [AEP] determines at which measured value the output
signal is 20 mA�
Minimum distance between [ASP] and [AEP] = 20 % of the final value of the
measuring range�
