3 Inline refractometer sensor
3.1 Mounting the sensor
The sensor mounting location should be chosen with care to ensure reliable readings
from the process.
3.1.1 Choosing sensor mounting location
The mounting location needs to be such that sediments or gas bubbles cannot accu-
mulate by the sensor. Good flow velocity is essential in keeping the prism clean.
Important: If the process pipe vibrates, support the pipe. A vibrating pipe might dam-
age the in-line sensor mounted on it.
The sensor cover should not be exposed to high temperature radiation. In most cases,
draft and natural convection provide sufficient air cooling if the air gets to flow freely
around the sensor head.
