Electromagnetic flowmeter empty pipe alarm how to set?

When the electromagnetic flowmeter is in the setting state (for how to enter the setting state, please refer to the above operations, use the ▲ or ▼ keys to scroll up and down the screen to search until the empty pipe alarm introduction appears on the screen, press the right button to confirm and enter the empty pipe Alarm permission settings, use the ▲ key to select the introduction and prohibition options, press the right key to confirm, use the ▲ key to select the empty traffic alarm threshold setting, press the right key to confirm, enter the empty traffic alarm threshold setting, enter the empty traffic alarm value, press the right button to confirm, press the ▲ button to select the empty pipe range correction setting, press the right button to confirm and enter the empty pipe range correction setting, enter the empty pipe range correction value, press the right button to confirm and return. If left on for 3 seconds, it will return directly to the display state. If you want to continue setting other parameters, press the ▲ key.

Note:

1. When the instrument detects the empty pipe status, it will return to the display state. Setting the empty pipe alarm to allow will set all the instrument output and display to 0;

2. The empty pipe alarm threshold setting is to select the empty pipe alarm sensitivity range. The *threshold can be set to 999.9% if it exceeds the The value means empty pipe;

3. Empty pipe range correction is used to measure relative conductivity. When the sensor is filled with liquid, the correction coefficient makes the conductivity ratio a certain value. The value range is 0~3.999 For example, if the measured liquid is water, its conductivity is about 100us/cm. The correction coefficient can be set to 1 for empty pipe alarm or the value can be set to 999.9%; when the measured liquid is acid, alkali and salt, its conductivity is greater than 100us. The /cm correction coefficient can be set to Xiaogan 1. The empty pipe alarm threshold is set to less than 999.9%. When the conductivity of the measured liquid is less than the conductivity of dry water, the correction coefficient can be set to be greater than 1. The empty pipe alarm threshold is set to Xiaogan 999.9%. ; In this way, false alarms will not occur. If false alarms occur, you can refer to the above to reset the correction coefficient and empty pipe alarm threshold;

4. Alarm prompt: The split electromagnetic flowmeter uses an empty pipe in the middle of the display screen. The word "Integrated" is represented by ! in the upper right corner of the display.

5. If the empty pipe range correction value and the empty pipe alarm threshold are not clear* select the empty pipe alarm to turn off.
