Zusammenfassung: | A sensing apparatus in the present disclosure is configured to measure magnetic flux of a magnetic field generated by a magnetic source and flowing through a sample slurry to determine magnetic permeability of the sample slurry. The sensing apparatus comprises a magnetic sensor inside a sensor housing that measures magnetic flux through a sensor housing made of a ferromagnetic material. The magnetic sensor sends measurements of the magnetic flux to a computing device that determines the presence of cementing fluids in the slurry based on the magnetic flux measurements. |
