Prowirl 200 Fixed Compensation Setup Overview
Prowirl 200 is a high-performance vortex flowmeter launched by Endress+Hauser and is widely used in industrial process measurement. Fixed compensation is a method of compensating for the influence of temperature or pressure changes on flow measurement by manually entering fixed values when the medium's operating conditions are stable. Correctly setting fixed compensation can improve measurement accuracy, especially in applications with small operating condition fluctuations.
Fixed Compensation Setup Steps
Preparation
- Confirm that the flowmeter is correctly installed and powered on.
- Obtain fixed compensation values such as the medium temperature and pressure.
- Prepare operating tools: a handheld communicator or commissioning software (such as FieldCare).
Operating Steps
- Enter the setup menu: access the main menu through the local display or a commissioning tool.
- Select Setup → Compensation → Fixed compensation.
- Select the compensation mode according to the medium type (temperature compensation or pressure compensation).
- Enter the fixed temperature or pressure value and confirm that the unit is correct.
- Save the settings and exit, then check whether the measured value is stable.
Parameter Description
| Parameter | Description | Typical Value |
|---|---|---|
| Compensation mode | Select fixed temperature or fixed pressure | Fixed temperature |
| Fixed value | Manually entered compensation value | 20°C |
| Unit | Temperature or pressure unit | °C / bar |
Precautions and Best Practices
- Fixed compensation is only suitable for occasions with stable operating conditions. If the operating conditions fluctuate greatly, it is recommended to use dynamic compensation.
- Ensure that the entered values are accurate. Incorrect compensation will cause measurement errors.
- Calibrate the compensation values regularly to avoid accuracy degradation caused by changes in operating conditions.
- Refer to the Prowirl 200 manual for detailed parameters and fault codes.
