### 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.
