    Inline measurement is usually done with a density transmitter such as a vibrating tube or Coriolis based sensor installed in a recirculation line with stable flow. The signal is temperature compensated and trended against batch targets to detect dilution errors, air entrainment, or bitumen content drift. Installation quality matters, avoiding bubbles, ensuring full pipe, and providing steady flow. Operators typically validate inline readings with periodic lab checks using hydrometers or pycnometers. Inline density is best used as a consistency indicator, not a full replacement for residue tests.
