|
|
|
|
### 5. Low Flow Cut Off
|

|
|
|-----------|---------------|-------------------|--------|
|
|
| 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
|
|

|
|
|
|
### 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 |
|
|

|
|
|
|
## 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.
