As a new type of flow measurement instrument, electromagnetic flow meter helps us measure a lot of water, mud and other flows at work. But in practice, many users lose their passwords and have to restore factory settings. For this reason, the editor will share with you an article on the initial password and fault maintenance of the electromagnetic flow meter. I hope it will be helpful to everyone.

Initial password for electromagnetic flow meter:

No matter which level of password is used, the user can view the instrument parameters. However, if the user wants to change the instrument parameters, he must use different levels of passwords.

Level 1 password (factory value 00521): can only be viewed

Level 2 password (factory value 03210): Users can change 1~24 instrument parameters;

Level 3 password (factory value 06108): Users can change 1 to 25 instrument parameters;

Level 4 password (factory value 07206): Users can change 1 to 38 instrument parameters;

Level 5 Password (Super Password)

Passwords for levels 1 to 3 are determined by the user

What level of personnel control.

The super password of electromagnetic flow meter is 19818 It is unique to the manufacturer and can modify the password that ordinary users cannot modify.

The general password is 9194.

If someone sets a password, the solution is to short-circuit the reset jumper on the circuit board, but the consequence is that all passwords are cleared and all parameters are cleared, and a flow meter of this type has many parameters that are necessary, otherwise it will not work properly, including the most basic ones such as pipe wall thickness, material, diameter, medium properties, etc. Use with caution!

How to restore factory settings through panel settings? Why is the measured current 0 mA when the voltage is 24v?

The specific operation process is:

Press and hold ">" for 2.5 seconds to enter the menu. Note that there is A1 in the upper right corner of the screen. That is the page number of the menu. If you do not know English, you can enter the corresponding menu settings according to the menu page number to operate.

There is a voltage of 24V, and the measured current is zero. You have to pay attention to the wiring terminals above. The active output terminal is A+ A
