Getting closer to final completion

A long road behind and still some ahead, here are some pic of the viscometer in its state of completion.

Now to implement the ModBUS protocol and finish up this project.

Krebs to Poise Formula

Looking for a decent formula on the net for a Krebs to Poise conversion I’m left empty handed. I found a chart that had listed direct numerical conversions.

Here’s the Best Fit value in the Quadratic form ax^2+bx+c=y

y=0.00419037x^2+(-0.306745)x+6.40025
y=poise
x=krebs

It may be somewhat rough, but since KU is a unitless value…

(Update Nov 4, 2013)

Got some info from a fellow in Costa Rica that the formula seems to match more closely to Newtonian Poise. Using this for Thixotropic fluids would most likely be innacurate at best! I would agree since Thixotropic fluids require specific velocity differences to accurately determine viscosity at a value differing from standard measuring techniques.
