Solutions to common problems with radar level meter measurements

1. The new level meter installation and commissioning, to ensure the correct installation position, wiring to ensure that the line from the junction is bent downward to prevent water flow into the meter head, the best empty tank when the false echo storage, to determine whether the radar is normal according to the waveform.

2. Some sites need to set a high level, to communicate with the customer to set, and the range of the central control or secondary meter should be consistent with the low level of the table minus the high level.

3. If the site radar has no waveform or the curve is not normal, there is a relatively slow response, and there may be a problem with the site voltage, first determine the site voltage and the output current of the radar.

4. If the radar shows E14, the radar does not range, then you need to determine what the problem is according to the waveform. If there is no signal, there is a possibility that the range is not enough, you can increase the range to observe. If this method does not work, you can try to restart, and if conditions allow, you can also take out the radar to other places to try.

5. Installed in the site with a waveguide tube, the general waveform is messy, you need to set the waveguide tube option, you need to turn the flange until the waveform is better to stop, it is best to learn the false echo when the material is less.

6. With the universal measurement of solid powder site, generally need to adjust the angle, of course, when the material is less good to find a suitable angle fixed to ensure that the maximum signal, the signal of the measured powder to ensure that more than 45dB if the signal is still relatively small or waveform is not good, it may also be the horn mouth dust accumulation.

7. Measure the liquid in the case of less material may appear jump, the value to the empty tank jump, when the radar may be measured to the bottom of the tank, and the signal of the bottom of the tank is greater than the signal of the material level, then you can properly reduce the range to avoid the signal of the bottom of the tank.

8. If the radar is no signal due to water, we need to remove the board to see if there are water droplets, if there is water, you need to wipe the water clean, if it still does not work, you need to remove the horn, wipe the water inside the Teflon tip and sensor

9. Contact radar level meter should first see whether the installation position is correct, whether there is a waveguide tube at the scene, whether the probe has touched other obstacles by waveform judgment, and whether the probe should be more than 20 cm from the bottom of the tank.

10. If the distance is not measured, first look at the waveform, if normal, you can generally adjust the threshold value smaller, preferably not less than 5, you can also enlarge the range appropriately. If the value jumps, it depends on which position to change, if the jump to zero, you can reduce the range appropriately. In addition, the problem of jumping can also be solved by setting false echo learning.

11. Can communicate to determine whether there is a problem with the parameters first, and then determine the problem through the waveform. If the current is relatively small and can not communicate, you can first increase the current by pressing the button to adjust the low level to increase the current and then finally change the parameters back. Some sites can communicate in the central control line cabinet, to communicate can not use their own power. Can not communicate through the key debugging, first to determine whether there is a problem with the parameters, and then look at the signal judgment, if the measurement is accurate and the upper row of the signal is greater than 30 basics there is nothing wrong. If the display E040 is generally a bad circuit board, you need to replace the circuit board.

12. If there is no signal or the signal is very small, there are generally two situations, one is that the rod antenna is not material, so there will be no signal, you can increase the range to 30 centimeters. The second is not connected to the sensor, the waveform baseline at this time will be very high, always measuring the front.
