The setting method of electromagnetic flowmeter empty pipe alarm includes entering the setting interface, enabling the empty pipe alarm function, setting the empty pipe alarm threshold and other steps.
How to set the empty pipe alarm of the electromagnetic flowmeter:
Button description: From left to right are the front, second, third and fourth keys.
Press two keys forward to move the cursor to the left. Press three keys to the front to move the cursor to the right. The second key is the number minus key, and the third key is the number plus key.
1. Press the front and four keys together to display the "Parameter Settings" menu;
2. Press the fourth key to display "0000" or "00000" to set the password. Enter";
3. After setting the password, press the front and fourth keys at the same time to display the "Language" item;
4. Press the third key to scroll down the menu Until the "empty pipe alarm" item appears, there is a prohibition and permission item in the menu;
5. After setting, press and hold the fourth key to exit the menu and return to the normal measurement interface.
The measurement principle of electromagnetic flowmeter is Faraday's law of electromagnetic induction. It is an instrument that measures the flow of conductive fluid based on the electromotive force induced when an external electromagnetic field is applied. The advantage of electromagnetic flowmeter is that the pressure loss is extremely small and can be measured. The measured flow range is large. The ratio of large flow rate to small flow rate is generally more than 20:1. The applicable industrial pipe diameter range is wide, up to 3m. The output signal is linear with the measured flow rate, and the accuracy is high, and the conductivity can be measured. Fluid flow rate of ≥5μs/cm, such as acid, alkali, salt solution, water, sewage, corrosive liquid, mud, mineral pulp, paper pulp, etc. But it cannot measure the flow rate of gas, steam and pure water.
