I was working on calibrating turbidity transmitters endress+hauser at effluent polishing plant.We calibrated using NTU buffers.What happened is that when we immersed the sensor, everytime we raise and lower the sensor gradually, the reading will vary.my question is that is there any specifications on what is the required distance from the bottom of the container with buffer to the face of the sensor?Is it ok to install the sensor in a medium which has turbulence specially if bubbles are present?
