OLR Series 1000 OnLine Rheometer

The OnLine Rheometer (OLR) is designed to continuously measure, plot, and report the rheological properties of drilling, completion, and fracturing fluids in the pipe. The OLR uses a squeezeflow technique; it measures storage and loss moduli by imposing a small cyclic deformation on a liquid sample at a variety of frequencies, from 1-100 Hz. Quality control parameters and user interface are based on ?* (complex viscosity [Pa s]), as measured by the OLR. The response of the liquid is measured and displayed in terms of G' (storage modulus [Pa]), G'' (loss modulus [Pa]), d (phase angle [Degrees]), and n*.
