Key Configuration Differences

1. Measurement Units

Parameter	Factory Values	Water System Values	Impact
Volume flow unit	l/h	l/min	Higher precision for real-time process control
Volume unit	dm³	l	More practical unit for process monitoring
Mass flow unit	kg/h	kg/min	Consistent with volume flow time units

2. Communication and Fieldbus

Parameter	Factory Values	Water System Values	Impact
Device address	126	20	Specific address in PROFIBUS network
Status PROFIBUS Master Config	Not active	Active	Confirmation of active communication with PLC
PROFIBUS baudrate	Not available	1.5 MBaud	Specified communication speed

3. Analog Output Configuration

Parameter	Factory Values	Water System Values	Impact
0/4 mA value (Output 1)	0.000 l/h	0.000 l/min	Adjusted to system units
20 mA value (Output 1)	18000.00 l/h	200.000 l/min	Range adjusted for water dosing (18000 l/h = 300 l/min)
100% bargraph value 1	18000.00 l/h	200.0000 l/min	Display range consistent with operational range

4. Pulse Output Configuration

Parameter	Factory Values	Water System Values	Impact
Value per pulse	2.5000 dm³	1.5000 l	Adjusted for more precise totalizing

5. Low Flow Cut Off

Parameter	Factory Values	Water System Values	Impact
On value low flow cutoff	300.0000 l/h	3.0000 l/min	Adjusted to eliminate noise readings when idle (300 l/h = 5 l/min)
Off value low flow cutoff	50%	50%	No change

6. Totalizer Configuration

Parameter	Factory Values	Water System Values	Impact
Unit totalizer 1	m³	l	More practical unit for process monitoring
Unit totalizer 2	m³	l	More practical unit for process monitoring
Unit totalizer 3	m³	l	More practical unit for process monitoring

7. Calibration and Adjustments

Parameter	Factory Values	Water System Values	Impact
Calibration factor	0.7688	0.7688	No change
Zero point	5e-01	5e-01	No change
Calibration date/time	16.01.25 18:29	16.01.25 18:29	Same calibration

Signal Processing Parameters

The signal processing configuration remains unchanged between factory settings and the Water system configuration:

• Flow damping: 4 (filter application)
• Filter options: Binomial
• Median filter depth: 1
• Response time 95%: 0.5 s

These settings provide optimal noise filtering while maintaining good response characteristics.

Recommendations

1. Flow range validation: Verify that the configured range of 0-200 l/min is appropriate for all operating conditions of the Water system.

2. System integration verification: Confirm that the PROFIBUS address (20) is correctly recognized by the control system.

3. Pulse output monitoring: Since the pulse output is configured to 1.5 liters per pulse, ensure that any connected systems correctly interpret this value for accurate totalization.

4. Document future calibrations: Maintain records of any additional adjustments made to the instrument.

Conclusions

The Promag 500DP configuration for the Water system has been specifically adapted to:

1. Work with more appropriate units for the process (l/min instead of l/h)
2. Establish measurement ranges appropriate for water dosing (200 l/min)
3. Configure pulse output with an appropriate value per pulse for accurate totalization
4. Set up PROFIBUS communication with the appropriate address for the system

These changes optimize the flowmeter's performance for its specific application in the water dosing process. The signal processing parameters provide a good balance between noise filtering and response time, which is important for accurate measurements in water applications.
