The Guda radar level gauge always shows the full scale
Thread Content
This level gauge has been in use since I arrived here, and it has been very stable; however, a few days ago it suddenly showed 9.80 meters. The full-scale range is set at 10 meters, and the liquid being measured is hydrochloric acid. There was also no code indicating that no echo could be received; regardless of the distance, whether it was close or far, the range display remained unchanged at all. Only after turning off the power supply and then turning it on again. There will be a normal liquid level display for about 10 seconds, after which the level keeps rising until it reaches the full scale. What could be the cause of this, and can it be fixed?
To perform interference suppression, when you turn off the power everything works normally; that is the initial value after the meter restarts.
If possible, try replacing the circuit boards (it may be several boards; first turn off the power and remove them once, and if that doesn’t work, replace the signal board). Alternatively, contacting the manufacturer’s technical staff can help identify the cause more quickly.
The reason? Intermittent neuropathy, madness – it finally breaks out. There’s no end to the dissatisfaction… Once it starts, the condition becomes severe, and even turning off the power and restarting doesn’t help. . . . Do you know why he’s unsatisfied and causing trouble for you? I guess it’s Radar Ray the madman; he wants a girlfriend to kiss. . . You can find another idiot for him to hook up with. . . . . It is said that that certain person’s mother hasn’t had any episodes of madness since giving birth to him. . .
God, I knew you hated radars and ultrasonic waves the most.
It’s possible that the circuit board is damaged; does the gauge display E14 or E13? It’s best to take a photo of the echo curve for inspection. Additionally, radar level gauges actually have a diagnostic period of around 30 seconds when powered off and restarted; the current usually rises from 3mA to around 27mA. After the diagnosis is complete, it’s normal for the current to stabilize at 4-20mA. So the values you mentioned during the power-off restart are accurate, while the inaccurate values that appear later may also be due to a misunderstanding
