Su's funnel viscometer ZLN-1A

1、 Overview

ZLN type Su style funnel viscometer is used to determine the relative viscosity of drilling fluid (compared with water). It is widely used in petroleum, geological exploration and other departments, especially in field drilling sites, as a simple instrument for daily measurement of drilling fluid viscosity. Due to the significant influence of colloid fraction and specific gravity on the measured data, this instrument cannot be directly compared with the data measured by rotational viscometers, static shear forces, and rheometers.
