Totalizer Reset Overview
Totalizer Reset is a common operation in the daily maintenance of flowmeters, used to zero the accumulated flow value for segmented measurement or restarting statistics. This article uses Endress+Hauser's Promag 53, Promass 83, and Prosonic 93 as examples to explain the reset process. Before operation, please confirm that the current accumulated value has been recorded to avoid data loss.
Applicable Devices and Prerequisites
Supported Models
- Promag 53: Electromagnetic flowmeter, commonly used for conductive liquid measurement.
- Promass 83: Coriolis mass flowmeter, suitable for high-precision mass flow measurement.
- Prosonic 93: Ultrasonic flowmeter, used for non-conductive liquids or open channel measurement.
Prerequisites
- The device is powered on and in normal measurement mode.
- The user has operator or engineer permissions (some models require a password).
- The current accumulated value has been backed up or recorded.
Totalizer Reset Steps
General Operation Procedure
The following steps apply to the three models mentioned above. Specific menu names may vary slightly; please refer to the actual device display.
- Press the E key to enter the main menu.
- Use the + or - keys to select the "Operation" or "Maintenance" menu.
- Enter the "Totalizer" submenu.
- Select "Reset Totalizer".
- Confirm the reset operation and press the E key to execute.
- The screen displays the totalizer zeroed, and the reset is complete.
Model Differences
| Model | Menu Path | Remarks |
|---|---|---|
| Promag 53 | Main Menu → Operation → Totalizer → Reset | Supports partial reset or full reset |
| Promass 83 | Main Menu → Operation → Totalizer → Reset | Confirm mass flow unit |
| Prosonic 93 | Main Menu → Maintenance → Totalizer → Clear | May require password entry |
Precautions and Common Issues
Precautions
- Always record the current accumulated value before resetting, especially for trade settlement applications.
- Some models support separate reset of partial totalizer and total totalizer; please select according to your needs.
- The reset operation does not affect flowmeter calibration parameters but may affect historical trend records.
Common Issues
- Value not zeroed after reset? Check whether the correct totalizer channel is selected, or try powering off and on again.
- Cannot enter reset menu? Confirm user permissions and enter the engineer password if necessary.
- Abnormal measurement after reset? Check sensor signals and recalibrate if necessary.
Correctly performing totalizer reset ensures the flowmeter continues to provide accurate accumulated data. If complex issues arise, it is recommended to contact the manufacturer's technical support.
