Treatment method for false liquid level phenomenon in side-mounted Magnetic level meter

The side-mounted magnetic level meter product can achieve high sealing, anti-leakage and safe and reliable liquid level measurement under high temperature, high pressure, high viscosity and strong corrosive conditions. The whole process measurement has no blind area, eye-catching display, and intuitive reading. , and the measurement range is large, equipped with liquid level alarm and control switch, can realize the upper and lower limit alarm and control of liquid level or boundary level, and equipped with liquid level transmitter to convert the liquid level boundary signal into two-wire 4~20mADC It can realize long-distance detection, indication, recording and control.

The working principle of the side-mounted Magnetic level meter:

A new type of instrument that uses the magnetic steel in the float to drive the flip of the two-color sheet to indicate the liquid level. The magnetic float in the main body of the side-mounted magnetic flap level gauge moves up and down with the rise and fall of the liquid level, and at the same time drives the two-color sheet in the indicator outside the main body to turn over. . The line between the red and white bands represents the liquid level height. On the left side of the indicator there is a prominent graduated scale. This makes the liquid level indication appear clearer

Like any other instrument, Magnetic level meter will have some kind of situation in use. Today we will talk about what to do when there is a false liquid level?

The side-mounted Magnetic level meter is prone to false liquid levels in long-term use, which brings a lot of trouble to the user. The reasons for the false liquid level of the side-mounted Magnetic level meter are as follows. Several:

1. First make sure that both the liquid and gas phases are open!

2. Use a magnet to sweep the whole process along its surface, and you can realize that it will be corrected.

3. If it is a safe liquid, first let off the liquid phase and perform operation 2;

4. If the vapor pressure of the gas phase is high, close the gas phase valve, press the liquid in the pipe back to the storage tank, and perform the operation 2.

5. The external interference signal is too large, causing the circuit to obtain a false signal, not the actual measured signal;

6. The waveguide wire inside the side-mounted magnetic flap level gauge is faulty, such as looseness, poor sealing, water ingress and rust, etc., resulting in signal distortion;

7. The waveguide wire is not installed correctly, and the signal transmission is distorted;

8. The signal processing circuit is faulty.

The side-mounted Magnetic level meter is suitable for measuring various containers that are not convenient for side-mounted Magnetic level meter, especially for liquid level measurement in underground storage tanks. The side-mounted Magnetic level meter is widely used in industries and departments such as petroleum, chemical industry, metallurgy, electric power, light industry and medicine.
