Level transmitter calibration can be tricky but luckily, it’s also unnecessary most of the time. You rarely need to calibrate level transmitters in the field. When the companies build these devices, they use a verification and calibration device to fake various distances and conditions. This way, they see how the device behaves and if it reads the distances and conditions correctly, it can be considered calibrated.

Once we had a customer insist that all his field devices needed calibration. We found him a calibrated electronic measuring tape to compare with the radar in the workshop, he played with that for a while, and everybody went home happy.
