The causes and solutions of the failure of the magnetic flap level gauge to make your data more accurate

I think many people say that level gauges are now playing an important role in many aspects. There are also various types of tuning fork vibration type, magnetic levitation type, pressure type, ultrasonic, sound wave, magnetic flap, radar and so on. Today, the editor will introduce the causes and solutions of a hydraulic machine called a magnetic baggage measuring instrument. If you are interested, let’s take a look.Magnetic plate level gaugeExplain the cause and solution of the malfunction of the magnetic baggage measuring instrument1. Failure phenomenon: The field instrument has no display, and the transmitter output is a constant current value; the field instrument displays normal, but the output of the transmitter is fixed at about 2.1mA, or the output is unstable.Reason analysis: The level gauge with the above failure phenomenon is normal at one time. It may be caused by incomplete storage of the instrument during construction, and no protective measures after installation and installation, resulting in damage to parts of the circuit board with poor insulation.Solution: Replace the display board or expansion board, re-enter the human parameters, and perform linear adjustment.2. Failure phenomenon: The field instrument display is consistent with the output of the transmitter, but the instrument failure is not good; and the range fluctuates greatly, the output is unstable, and the linearity is poor.Cause analysis: collision in transportation, force error in installation, and external force on the torsion tube after installation.Solution: When the torsion is damaged, replace the torsion tube, re-enter the human parameters, and adjust to linear; In addition, a float hook is severely bent and deformed, and it is normal after recalibration.3. Trouble phenomenon: E2 and E3 error codes are displayed, and sometimes the output of the transmitter will rebound sharply.Reason analysis: due to the long interval between meter installation and dosing, the meter is not well sealed, and the meter is affected by humidity, rain and blisters for a long time. For the meter with this kind of failure phenomenon, after opening the meter cover, most of the cavity walls are Droplets or aluminum rustSolution: Replace the angle converter, re-enter the human parameters, and perform linear adjustment.Magnetic plate level gauge4. Trouble phenomenon: The output and indication are incorrect. According to different manuals, the zero point and range cannot be adjusted.Reason analysis: due to installation and careless adjustmentSolution: Perform linear adjustment again.5. Failure phenomenon: the model is inconsistent, the accuracy of the instrument is reduced, and the transmitter of the measurement interface is designed based on liquid level measurement.Reason analysis: the supplier’s juice production error.Solution: Replace the float, re-enter the human parameters, and perform linear adjustment.6. Trouble phenomenon: The instrument cannot accurately indicate the liquid level, and the output of the instrument changes slowly with the liquid level.Reason analysis: the steam of organic materials condenses and crystallizes or becomes thicker at the connecting rod mechanism of the instrument and the upper and lower limit blocks.Solution: Put the steam pipeline into the ventilation port, clean it with steam regularly, and heat the steam for the instrument box.Magnetic plate level gaugeI have read the introduction of the editor above. You should already know what kind of malfunctions will happen to the magnetic water level gauge, but don’t worry too much. These faults have been solved very effectively. Of course, a better way is to choose products that are very guaranteed in terms of performance, but Hokkoda’s instruments are the best choice for everyone. The instruments they produce can avoid these failures very well, so if you have a demand , I believe the brand recommended by the editor is absolute
