Treatment of false liquid level in side-mounted magnetic level meter
Treatment of false liquid level in side-mounted magnetic level meter can achieve high sealing, anti leakage and safe and reliable liquid level measurement under high temperature, high pressure, high viscosity and strong corrosion conditions. There is no blind area in the whole process of measurement, the display is eye-catching, the reading is intuitive, and the measurement range is large. Equipped with liquid level alarm and control switch, it can realize the upper and lower limit alarm and control of liquid level or boundary, Equipped with a liquid level transmitter, the liquid level boundary signal can be converted into a two-wire 4~20madc standard signal to realize remote detection, indication, recording and control.
Working principle of side mounted magnetic level meter:
A new type of instrument that uses the magnetic steel in the float to drive the turning of the two-color sheet to indicate the liquid level. The magnetic float in the main body of the side mounted magnetic flap liquid level gauge moves up and down with the rise and fall of the liquid level, and drives the two-color flakes in the indicator outside the main body to turn over. When there is a liquid level, it turns red, and when there is no liquid level, it turns white. The boundary between the red and white bands represents the liquid level. A striking scale is provided on the left side of the indicator. So as to make the liquid level indication more clear
The magnetic flap is the same as any other instrument. There will be some situations in use. Today we will talk about what to do when there is a false liquid level?
The side mounted magnetic flap liquid level gauge is prone to false liquid level in long-term use, which brings several troubles to users. The reasons for the false liquid level of the side mounted magnetic flap liquid level gauge are as follows:
1. First, make sure that the liquid phase and gas phase are connected!
2. Use a magnet to sweep the whole process along its surface, and you will realize that it will be corrected.
3. If it is a safe liquid, first discharge the liquid phase and execute operation 2;
4. If the vapor pressure of the gas phase is large, close the gas phase valve, press the liquid in the pipe back to the storage tank, and execute operation 2.
5. The external interference signal is too large, causing the circuit to get 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 inflow and rust, resulting in signal distortion;
7. Incorrect installation of waveguide wire and distorted signal transmission;
8. Signal processing circuit failure.
The side mounted magnetic level meter is suitable for measuring all kinds of containers that are not convenient to install the liquid level gauge on the side, especially the liquid level measurement in the underground storage tank. The side mounted magnetic flap level gauge is widely used in petroleum, chemical industry, metallurgy, electric power, light industry, medicine and other industries and departments.
