E+H guided wave radar

First, determine whether the power supply is functioning properly; check if the isolation device between the instrument and the controller is working correctly. Then, verify whether the radar level gauge is in an alarm state – for example, check if the sensor is contaminated

It depends on what type of medium you have; in the areas where there is a high level of dust, this situation occurs frequently!

OP, considering the medium being measured (since it is a liquid), it’s not interference. If it is interference, the liquid level will fluctuate. There are probably two possibilities: the guide rod of the level gauge has hit the bottom ； The parameters of the level gauge have changed.

Reply to 2# hhidb: None of the above situations apply, but thank you.....

Reply to 2# hhidb: For every such thing, it’s great; it’s been written down

Errors occur only when external interference is present. 1. Check whether the power supply is functioning properly. 2. Determine if there is any external interference. 3. You can try turning off the power and then reconnecting the instrument

It is recommended to use the level gauges produced by our factory – they can effectively handle dust and mist, serving as a perfect replacement for radar and ultrasonic level gauges; QQ164000461

Set the lower limit for the empty mark and the upper limit for the full mark; it’s best to set them slightly above his measured values

1. Try turning the power off and on again. 2 If it is still abnormal, clean the guide rope. 3. If nothing else works, just use a laptop to connect and view the waveform chart..

Your description is not clear, so I will provide answers for two possible scenarios for now: 1. If the value displayed on-site is not 0 but the output is 0, it is recommended to open the cover of the device. There are two test terminals next to the output terminals; by connecting the two probes of a multimeter directly to these test terminals, you can measure the output current without having to insert the probes into the output circuit. If the output is 4mA or 0mA, it is likely that the internal electronic components are damaged. It is suggested that you try replacing the faulty component with one from the same model to determine which board is defective. 2. Both the on-site value and the output value are 0; it is recommended that you check the application software, clean the waveguide cable, etc., select \"slow change\" as the tank type, and try recalibrating it. Also, I really despise those who criticize that ad; the person is just asking for technical advice, and you go and tell them to use yours instead. It’s absolutely detestable!
