Promag 10 Totalizer Reset to Zero Overview
Promag 10 is an electromagnetic flowmeter launched by Endress+Hauser, widely used for flow measurement in water treatment, chemical, food, and other industries. The totalizer is used to count the total flow over a period of time. When a process batch ends or remeasurement is required, the totalizer value needs to be reset to zero.
The reset operation can be completed through the on-site display panel without additional tools, but attention must be paid to permissions and operation confirmation to avoid data loss caused by accidental zeroing.
Preparation Before Reset
Confirm Operation Permissions
- Confirm whether the current user level allows modification of the totalizer value; usually it is necessary to enter the Expert menu or input an unlock code.
- Record the current totalizer value; if necessary, take a photo or write it down for later verification.
Confirm Process Status
- Ensure that the reset will not affect ongoing batch measurement or trade settlement.
- If the instrument is connected to a control system, notify the central control personnel in advance.
