Fann VG 600 RPM Fann model 35SA Direct Indicating Viscometers combine accuracy with simplicity of design, and are recommended for evaluating materials that are Bingham plastics.

2018年11月15日 · This document summarizes an experiment testing the rheology of mud samples using a Fann VG-Meter viscometer. The experiment involved mixing water with different amounts of bentonite to create mud samples. The mud samples were tested at 600 and 300 rpm speeds and the dial readings measuring viscosity were recorded.

2019年4月4日 · Fann V-G Meter Also known as direct-indicating viscometer or V-G meter, an instrument used to measure viscosity and gel strength of drilling mud. The direct-indicating viscometer is a rotational cylinder and bob instrument. Two speeds of rotation, 300 and 600 rpm, are available in all instruments, but some are 6- or variable-speed.

The Fann Model 35 Viscometer is widely known as the “Standard of the Industry” for drilling fluid viscosity measurements. The Model 35 Viscometer is a versatile instrument for research or …

2016年1月27日 · Both parameters can be determined from the Fann VG meter. “k” is defined as the viscosity of a fluid at a shear rate of 1 sec-1. When “n” equals 1, the fluid is Newtonian. As the fluid becomes more shear thinning, the “n” value decreases.
