Why does Endress+Hauser Micropilot FMR52 display a level when the tank is empty?
If the Endress+Hauser Radar displays a level when the tank is empty, it's likely due to an interference echo. Perform a mapping over the entire measuring range when the tank is empty by using the Confirm distance parameter.
What to do if Endress+Hauser Radar measured value is incorrect?
If the measured value of your Endress+Hauser Radar is incorrect, here are a few things you can check: * If the measured distance matches the real distance, there may be a calibration error. Check and adjust the Empty calibration parameter, Full calibration parameter and linearization if necessary. * For measurements in bypasses or stilling well, ensure the correct tank type is selected and the tube diameter parameter is correct. Select 'Bypass / pipe' for the tank type and enter the correct diameter in the Tube diameter parameter. * Enter the correct value in the Level correction parameter. * If the measured distance does not match the real distance, there may be an interference echo. Carry out tank mapping.
Why there is no change of measured value on filling / emptying with Endress+Hauser Micropilot FMR52?
If there's no change in the measured value during filling or emptying with your Endress+Hauser Radar, it's likely due to: * Interference echo from installations, nozzle, or build-up on the antenna. To resolve this: * Carry out tank mapping. * Clean the antenna if necessary. * Select a better mounting position if needed.
What to do if Endress+Hauser Radar measured value jumps sporadically to a higher level?
If the measured value jumps sporadically to a higher level when the surface is not calm (e.g., during filling, emptying, or when an agitator is running) with your Endress+Hauser Radar, it's likely because the signal is weakened by the rough surface, making interference echoes stronger. Here are some steps to take: * Carry out tank mapping. * Select 'Process vessel with agitator' for the Tank type. * Increase the integration time. * Optimize the antenna orientation. * Select a better mounting position and/or larger antenna if necessary.
How to fix error message F941 or S941 "Echo lost" on Endress+Hauser Micropilot FMR52?
The error message F941 or S941 "Echo lost" on your Endress+Hauser Radar indicates that the level echo is too weak or suppressed. To resolve this: * Check the Medium group parameter. If necessary, select a more detailed setting in the Medium property parameter. * Optimize the alignment of the antenna. If necessary, select a better installation position and/or larger antenna. * If the level echo is suppressed, delete the mapping and record it again.
Why Endress+Hauser Micropilot FMR52 device measures incorrectly?
If your Endress+Hauser Radar device is measuring incorrectly, it may be due to a parametrization error. Check and adjust the parameterization.
Why does the measured value jump sporadically on Endress+Hauser Micropilot FMR52?
If the surface is not calm and the measured value jumps sporadically to a higher level on your Endress+Hauser Radar, the signal is weakened by the rough surface. Perform tank mapping and select the tank type as 'Process vessel with agitator'. Increase the integration time and optimize the antenna orientation. Selecting a better mounting position or a larger antenna may also help.
Why is the measured value incorrect on my Endress+Hauser Micropilot FMR52 Radar?
If the measured value on your Endress+Hauser Radar is incorrect, check and adjust the Empty calibration parameter and the Full calibration parameter. If necessary, check and adjust linearization. For measurements in bypasses or stilling wells, select the correct Tank type (Bypass / pipe) and enter the correct diameter in the Tube diameter parameter. You may also need to enter the correct value in the Level correction parameter.
What to do if Endress+Hauser Radar device does not respond?
If the Endress+Hauser Radar device does not respond, ensure that the supply voltage matches the value indicated on the nameplate by connecting the correct voltage. Also, check and correct the polarity if it's wrong. Finally, ensure proper electrical contact between the cables and terminals.
What to do if "Communication error" is indicated on the Endress+Hauser Micropilot FMR52 display?
If a "Communication error" is indicated on the display of your Endress+Hauser Radar when starting the device or connecting the display, it could be due to: * Electromagnetic interference. Check the grounding of the device. * A broken display cable or display plug. Exchange the display.
