Berthold LB444
For continuous measurement of liquid or bulk density, the LB 444 system uses proven 2-wire technology for installations requiring a non-intrusive, non-contacting measurement.
With the source and detector clamped on the exterior of the pipeline, vessel, or chute, the system does not contact the process and therefore offers an advantage when measuring materials which cause erosion, plugging, and coating. The LB 444 allows for easy calibration and configuration through the local display, making it ideal for installations where the control system is not HART or FOUNDATION Fieldbus compatible.
