Electromagnetic flowmeter reading zero how to adjust?

Case introduction

1. Zeroing method of electromagnetic flowmeter

Electromagnetic flowmeter is a commonly used flow measurement equipment. In order to ensure the measurement accuracy, the electromagnetic flowmeter needs to be reset to zero. The following will introduce two methods of manual zeroing and automatic zeroing.

Manual zeroing method:

1. Press the "CLEAR" or "ZERO" button on the meter head.

2. Wait for the electromagnetic flowmeter indicator light to turn green or the display to return to zero, which means the zeroing is successful.

Notes:

1. When performing manual zeroing, it is necessary to ensure that there is no fluid flow in the pipe to avoid affecting the zeroing effect.

2. Do not operate other buttons before zeroing is completed.

Auto-zero method:

1. Enter the menu interface and select the "Auto-zero" function.

2. Wait for the indicator light to turn green or the operation display to return to zero, which means the automatic zero return is successful.

Notes:

1. Automatic zeroing must be performed within the specified measurement range, otherwise the zeroing effect may be affected.

2. If you encounter zeroing failure, please try to reset to zero manually.

2. Operation skills

1. Before performing the zeroing operation, it is necessary to ensure that the operating voltage of the electromagnetic flowmeter is stable to avoid measurement errors.

2. Manual zeroing requires pressing the button and waiting for the indicator light to turn green. Only in this way can the successful zeroing be guaranteed.

3. Automatic zeroing needs to be performed within the specified measurement range, otherwise it will affect the zeroing effect.

3. Summary

The above are the detailed methods and precautions for zeroing the electromagnetic flowmeter. Correct zeroing operation can ensure the measurement accuracy of the electromagnetic flowmeter. Appropriate operating skills can improve the efficiency of zeroing, allowing the electromagnetic flowmeter to better serve production practice.
